In projection technology, sensations are extremely rare. But the event that occurred at the end of last year fully deserved such a definition. The professional division of Sony presented its latest development in Moscow - the ultra-short throw projector VPL-GTZ1.

The ability to work at a minimum distance from the screen itself is no longer exclusive - such devices have been produced for several years and are widely used in the field of education, since they allow the teacher to be in close proximity to the image without casting a shadow on it. What is fundamentally new and very significant is that the new product from Sony has a physical resolution of 4K, and that it uses laser LEDs as a light source. Judging by the technical characteristics, the potential of the model goes far beyond the sphere of education or business, however, it was impossible to evaluate the real image quality in the presentation conditions, so I reserved my opinion until a closer and more direct acquaintance. Suitable conditions for this were created in the showroom of the Digital Systems Group of Companies in Moscow.

WITH A SCREEN DIAGONAL OF 147” AND A MAXIMUM SHORT FOCUS LENS, THE DISTANCE BETWEEN THE WALL AND THE REAR EDGE OF THE PROJECTOR IS ONLY 17 CM, THE DISTANCE TO THE FRONT EDGE IS 70 CM.

I have written more than once: the smaller the distance between the projector and the screen, the more stringent the requirements for the reflective surface and the accuracy of the installation of the device. But even with a perfectly flat and smooth screen, the main problem of such installations remains - the large difference in the distance that the rays of light have to overcome when forming the lower and upper parts of the picture and the sharp angle of incidence of the rays on the surface at the farthest area of ​​the screen. Because of this, the uniformity of illumination suffers (when the projector is installed on the floor, the lower part of the image turns out to be brighter than the upper), strong geometric distortions occur and clarity decreases, since the image-forming points at acute angles of incidence are stretched vertically and acquire an elliptical shape. Naturally, all these distortions must be compensated. The easiest way is in the digital path, as for example, this was done in a projector, but there, due to correction, the displayed video resolution was reduced, which had a very detrimental effect on the quality of the picture. Another method, more correct, but technically complex, is transformation in the optical path, which is what was implemented in the VPL-GTZ1. Naturally, the design turned out to be extremely complex, quite large and heavy - the solid dimensions, weight and price of the projector are largely due to the optical path (the lens is only a small, visible part of it). There were some sacrifices: we had to abandon the image shift function - if you need to raise it, the manufacturer advises using a special podium (stand). The device we tested was installed on a custom-made cabinet. Ceiling placement is also possible - if you are sure that your ceiling will withstand 55 kg, not counting the suspension.

To be honest, I don’t know if it’s possible in principle to create such a projector with a lamp as a light source. Theoretically, this is probably possible, but it would be too bulky and heavy, since it would have to be an effective cooling system and also provide for the possibility of replacing the lamp. The laser also has serious qualitative advantages: coherence, minimal beam divergence, and its light is quite easy to control. Other equally important advantages: high stability compared to lamps, long service life, quick readiness for work (about 12 seconds versus 60 for lamp-based projectors). Of course, at the current stage of technology development, such a light source is not cheap, although I doubt that its share in the final cost of the VPL-GTZ1 is very large.

THE SMALLER THE DISTANCE BETWEEN THE PROJECTOR AND THE SCREEN, THE MORE STRICT THE REQUIREMENTS ARE FOR THE REFLECTIVE SURFACE AND THE ACCURACY OF THE DEVICE INSTALLATION.

Be that as it may, this projector has crossed the line to which even small price deviations greatly affect sales volumes - it has entered a segment where capabilities, exclusivity and quality of work are decisive. Such equipment is purchased by people who know exactly why they need it and why it cannot be replaced by another, more affordable one. Functionality here is determined solely by expediency and technological capabilities, and not by strict cost limits. For example, the VPL-GTZ1 has an automatic calibration function: the device is capable of correcting deviations in the color balance that arise during operation. I don’t think that this opportunity was cheaper than periodic hardware calibration by a visiting specialist, but it is still more convenient: you do not need to invite a stranger and allocate your precious time for this.

Readers are probably already waiting for me to answer the question: is the use of this projector justified in a traditional home theater? Below I will tell you how it shows, and in comparison with a “regular” projector, but for now I will express my thoughts about possible options for its use.

Back in January 2014, the company presented the Lifespace UX concept at CES in Las Vegas (in the very first photo). This life style system, in addition to the ultra-short throw projector, should also include acoustics, electronic components and lighting elements made in the same style. In fact, this is an active decorative element that can decorate the interior with incredibly realistic paintings, as well as be an alternative to flat-panel TVs, which are stuck in their height at a diagonal of 85 - 90”*. The projection module of this system is VPL-GTZ1, but only in a light design.

*The record for LCD TVs made from a single panel belongs to the LG 105UC9 model with a diagonal of 105”. The largest “plasma” is the 152-inch Panasonic TH-152UX1. True, the mass of this monster is 577 kg, and the power consumption is 2.62 kW. Against this background, the VPL-GTZ1 with its maximum diagonal of 147” looks extremely light (55 kg) and economical (520 W).

Our hero in his business dark gray “suit” does not look so glamorous. I think its main area of ​​application is high-quality projection in places where the audience is not seated, but moves freely around the room. These can be elite nightclubs, dance halls, art galleries, as well as control centers and control rooms, where for certain reasons it is undesirable to use traditional video walls made up of smaller LCD panels. If necessary, you can put several of these projectors in a row and get an image of double or triple the width.

In principle, no one forbids using the VPL-GTZ1 in a home theater, although this option still seems too wasteful to me, since the largest part of the device’s cost is due to its ability to be installed in close proximity to the screen. It seems to me that in home cinema you can do without this. Nevertheless, let's consider this use case - not in terms of expediency, but from the point of view of image quality.

Usually I have to unpack and install the projectors myself, which are tested in our editorial office, but this time all this trouble was taken on by the specialists of Digital Systems. I know that the process was quite long and difficult. The most difficult thing is to orient the device as accurately as possible relative to the reflective surface and then correct geometric distortions - they arise even with a minimal deviation from the optimal position. Fortunately, a test grid is displayed on the screen, from which everything is immediately visible. In fact, absolute accuracy is not needed - small deviations from the ideal geometry not only on films, but even on presentation materials with text and tables are not noticeable. The difference in illumination of the lower and upper parts of the screen is also completely invisible, and this despite the fact that the room in which we tested the projector was completely darkened. Although the projector is designed to operate in dim ambient light, and the manufacturer recommends that the illumination in the center of the screen should not exceed 1.2 lux, at the very top - 0.6 lux and at the bottom - 4.5 lux. In the area of ​​the spectator's seat it can reach 80 lux. Approximately the same difference in illumination is achieved when conventional ceiling lamps are located in the central part of the room.

With a screen diagonal of 147" and the shortest possible lens focus, the distance between the wall and the rear edge of the projector is only 17 cm, the distance to the front edge is 70 cm. No one forbids moving the projector close to the wall, but the image diagonal will decrease to 106" (2 .69 m).

Even in the immediate vicinity of the screen, pixelation is absolutely indistinguishable: the picture looks completely smooth and uniform, like in analog cinema, only sharper.

A Sony FMP-X10 player was used as a 4K source; Blu-ray discs were viewed on a Cambridge Audio Azur 761BD player. The difference between the 4K demo material and the Full HD films was striking, but not so much in the clarity of the picture, but in its realism. For example, the clarity of 4K concert recordings was far from maximal due to the shooting conditions themselves, but the image still looked more authentic than 1080p, and therefore more impressive. I think it's not a matter of increased resolution, but a larger amount of information. In the days of analogue recording, a similar effect was observed as the area of ​​the magnetic media increased: 2-track tape recorders always sounded noticeably better than 4-track tape recorders at the same recording speed.

IF NECESSARY, YOU CAN PUT SEVERAL OF THESE PROJECTORS IN A ROW AND GET AN IMAGE OF DOUBLE OR TRIPLE THE WIDTH.

Perhaps this is the only ultra-short throw projector that I have ever seen on which even a spoiled viewer like me can enjoy watching movies without any reservations. Except for one thing: if for some specific reason it is necessary to use a device of this particular type. If nothing prevents you from installing a traditional cinema system, which can be placed on the ceiling or a special stand and does not impose any special requirements on the screen, then personally I would choose this boring and traditional option. I was convinced of this by looking after the VPL-GTZ1 at a top-end projector with a physical resolution of 4K -. A device with the same SXRD matrices, but with a conventional optical path, performed subjectively better. And this is not surprising: the closer the focal length of the lens is to normal, the better the picture. Although the feeling that you are at the forefront of technological development has, of course, disappeared.

Sony VPL-GTZ1

A unique combination of ultra-short focus and high image quality.

— High requirements for the screen: it must be of constant tension; the use of rollable sheets is not recommended.

Due to its price, this projector is hardly suitable for a home theater - even a top-end 4K Sony projector with normal optics will cost half as much. In this case, the image quality will definitely be better. However, in situations where spectators must move freely around the hall, the VPL-GTZ1 is absolutely indispensable.

When choosing a projector for your home, you will definitely have to decide whether you will use it only in a dark room (“home theater”), or whether you would prefer not to give up the opportunity to watch something (say football or a TV series) in the light. If so, then when choosing a projector you will probably consider its maximum brightness and, crucially, color quality at high brightness (since the more accurate the projector's color mode, the lower its brightness).

Such bright projectors that can work in an ordinary living room are often referred to on foreign websites as “home entertainment” projectors, that is, “projectors for home entertainment.” They are also often referred to as "TV replacements", although manufacturers themselves tend not to use these terms so as not to discourage those who would like to use the same models in a dark room, where they will provide the best picture quality. That’s why I was surprised that on Epson’s English-language websites about the model Epson EH-LS100 It is referred to as a “home entertainment” projector, and the device itself is constantly directly compared to a TV. Did they really decide to make a projector designed specifically for illuminated rooms?

Yes, this is exactly the case. Generally speaking, Epson home projectors, thanks to their three-matrix 3LCD technology, have long demonstrated the ability to achieve high brightness in combination with color rendition acceptable for a lit room (“color brightness” and all that...). This advantage made it possible to make universal home projectors that were not afraid of moderate lighting, although in the dark they showed themselves differently in terms of contrast, depending on the model. However, there has not yet been a projector that was initially conceived as a replacement for a TV and was designed for use in a bright room. But now such a model exists. We are, of course, talking about the hero of this review - the EH-LS100. Since I have already become familiar with this projector, first of all I will tell you how I see the thought process of its creators, or rather, what priorities they set for themselves (and successfully embodied in this model).

1. Do you think I'll start with brightness? But no.

The Epson website says: " Long-lasting light source: watch your favorite content for 10 years*
*5 hours a day, lamp in eco mode"

As you can imagine, we can say what we want, but a true “TV replacement” involves using the projector intensively, and not just watching one movie once a week.

The resource of the EH-LS100 laser light source is estimated at 20,000 hours and 30,000 hours in economy mode. More importantly, the Moscow representative office of the company told me that the warranty period for this model is 5 years of operation or 12,000 hours (whichever comes first is correct). THIS really sounds like a TV replacement approach. At least for me, this would be a serious argument that would alleviate a number of concerns.

2. The procedure for installing a projector is similar to the procedure for installing a TV: you place it on a low cabinet in front of a white wall or screen. If the cabinet has wheels, it can be moved freely.

As in the case of a TV, there are no restrictions in terms of freedom of movement in the room - it is impossible to get into a beam of light, and the audience seats can be located even close to the screen. All restrictions on the minimum room size are also lifted. Although note that I didn't say the projector itself was easy to carry - it's quite heavy (11kg), but it's still noticeably easier than carrying a 40-inch TV.

3. High brightness.

Looking at this projector, I was immediately reminded of the “Life Space UX” concept from Sony. As part of this concept, they are demonstrating a 4K projector with 2000 lumens of brightness (such as the LSPX-W1S), which projects directly onto the wall in a lit room. If you don't take into account 4K and HDR, then I have no doubt that the Epson EH-LS100 can easily surpass this $50,000 model in terms of picture richness simply because of the higher brightness, which plays a decisive role in the light. Of course, we are only talking about the advantage of the EH-LS100 in a lit room.

The point here is not only that the brightness of the EH-LS100 is two times higher than that of its analogues I have seen. The point is also that the brightest mode of the projector (“Dynamic”) turned out to be almost the most accurate of all the similar “Dynamic” modes I have seen on other projectors. This means that maximum brightness can and should be used when watching movies (unlike the vast majority of other models).

4. TV versus projector.

Since the “TV vs projector” debate has long been resolved, the projector buyer knows that he is paying for a large picture (100, 120, 130 inches or more), but loses in contrast, since the screen or wall is initially white, unlike the black TV screen. In this regard, the projector has the only chance to compensate for the lack of black - by increasing the brightness.

When I watched the night chase in The Dark Knight on the EH-LS100, my eyes tuned in to the bright light from explosions and city lights, perceiving the background as black. A contrast effect was created in the illuminated room and the film looked very beautiful. It was at that moment that I realized that the EH-LS100 had passed the test - it really is pleasing to the eye and you want to have it in your home. With light scenes everything is even more excellent, but with very dark scenes a problem will inevitably arise - to paraphrase the phrase of a famous politician, we can say that “it is useless to look for a black cat in a lighted room, especially if it is white.”

Note. By the way, there is another additional way to significantly improve the contrast in a lit room - use special screens that block background light. At least, the manufacturer has successfully used such screens at exhibitions, although they are usually not cheap.

5. Rainbow. Speaking about three-matrix projectors, I simply must note the absence of the “rainbow effect,” that is, a colored trail that occurs when the eye suddenly moves across the screen. Some people don’t care, while others perceive the absence of the “rainbow effect” as a sign of a higher quality image. The EH-LS100, of course, does not and cannot have a “rainbow”.

So we get a projector that has everything you need to replace your TV. I would like to immediately talk more specifically about its characteristics.

Brightness and Contrast

As a result of measuring the brightness (luminous flux) using the ANSI method, I got the following values ​​for each color rendering mode:

The data is given for various lamp modes: “normal”, “quiet/quiet” and “extended/long-lasting”.

It's worth noting that there is a particular problem when using ANSI with ultra short throw projectors: the sensor must be positioned perpendicular to the surface of the screen and the light from the projector hits the sensor at a very sharp angle, so the end result is slightly less than what the projector actually emits. If you tilt the EH-LS100 forward towards the screen so that the light hits the light meter sensor at a right angle, the maximum brightness will be higher (up to 7420 lumens, according to my data).

This clearly shows us what kind of “beast” is hidden under the hood of the EH-LS100. Of course, the picture of this projector looks brighter than the usual 3000 lumen models.

Brightness uniformity across the screen (9 points) is 68%. The top left corner was the least bright. If we exclude it, then the next dimmest part of the screen gives an illumination of 79% of the brightest. This is a very good level of uniformity for a short throw projector and is on par with many mainstream home projectors in the lower price range.

But the contrast of the EH-LS100 is low - 400:1 in the “Dynamic” mode and about 300:1 in other modes (the “full on/off” method, automatic iris off).

I said "Auto Iris" but instead, in very dark scenes the light output is controlled by the light source, just like laser projectors do. With “dynamic contrast” enabled, in “Dynamic” mode, when displaying a black screen, the projector completely turns off the light, making the screen perfectly black. In other modes, the light flux is partially blocked, and the dynamic contrast is 1400:1 (Game mode) - 1500:1 (all others). However, the problem with this projector's dynamic contrast is that it only works in very dark scenes and doesn't work in "dark enough" scenes where it could also provide a noticeable benefit and lower black levels. Traditionally, set dynamic contrast to a sharper or smoother mode, or turn it off.

As for contrast, even in a dimly lit room, a dark gray frame around the image will be noticeable, and horizontal stripes will differ from the color of the screen when viewing widescreen material. In the dark, you have no choice but to switch the projector to economy mode, still remaining at a higher brightness level than necessary. Well, black, obviously, will not correspond to the level that is expected from home theater projectors in this price group. But when you turn on the light, you realize that all these are little things when you see the bright picture of the EH-LS100. Translated into the language of motorists, the T-90 tank should not be directly compared with Lamborghini sports cars - you feel the pleasure of driving a tank when you stop feeling the difference, whether you are driving on a highway or across a field, or when you cross a small river on the move. . This is about comparing the EH-LS100 with home theater projectors.

The Epson EH-LS100 is the first projector that I preferred to watch in the light rather than in the dark, and it gives me a feeling of deep satisfaction that it has enough power to produce a really good picture in the light, although I mean, of course, indoor lighting, and not, for example, bright office lighting. And let's agree: no sun - even installation projectors can't cope with the sun! The EH-LS100 should work and be pleasing to the eye in moderate to low room lighting. And, as it may sound, the lack of significant improvement when viewing in complete darkness encourages the user to enjoy viewing in normal everyday conditions.

Think about it again: almost 5000 ANSI lumens with 98% color brightness (according to my measurements)!

Feelings from watching

As I said just above, the key test for the EH-LS100 was watching the movie “Black Knight” on the 120-inch screen with the room light on. Most of the film's dark scenes actually contained bright and dark areas in the same frame - bright lights and explosions were pleasing to the eye with sparkling shine and rich colors, and dark areas were perceived as truly dark despite the white screen. This is a rather curious effect - when a night scene is perceived as a full-fledged contrasting night scene - all these highlights and reflections on the glossy car bodies look so sharp and contrasting. In general, as expected, in a lit room the contrast of the image is enhanced by the impressive brightness of the projector, and the black level plays a minimal role*.

* Let me remind you that contrast is equal to the ratio of maximum brightness to minimum brightness, and in a lit room, the minimum brightness level of the projector itself (black level) becomes too unimportant, since the influence of background light is much stronger. You can increase the contrast in these conditions only by increasing the brightness.

Vivid scenes pleased me with their believability, accuracy of shades and smooth color transitions. When viewing a sunny daytime scene, the bright light caresses the eye, creating the impression of sunshine and naturalness, which is not always possible with projectors (I’ll call this the HDR effect).

While watching the helicopter attack scene from Apocalypse Now, I was glad that not only bright objects, but also medium-brightness objects looked good. For example, the faces of the characters look excellent - the colors are correct and not dull. But this particular film can give away a lack of black in some scenes.

Dunkirk looks great even in Dynamic mode. There's plenty of sun and the EH-LS100 will give you plenty of sun!

Watching all kinds of videos shot on GoPro, you pay attention to the “volume effect.” Sometimes this is facilitated by manually adjusting the Brightness/Contrast parameters. Either way, you can achieve a superb immersive experience.

But dark scenes in a lit room, as expected, suffer greatly and lose a lot. It’s good that there are few of them, and in most cases authors prefer to use contrasting scenes with bright spots.

Please note that this is the first projector where I preferred the brightest mode when watching movies. This indicates not only brightness, but also that color rendition in this mode is quite accurate. However, when viewing some animated works, there is a need for slightly more accurate shades, in which case I could switch to Vivid Cinema or Cinema modes (a matter of taste).

The very feeling of not having to turn off the lights adds fun to the viewing process.

And here's another thing: the EH-LS100 loves high-quality sources, it loves Blu-Ray. On low-quality sources with low bitrates, you will see all these artifacts, noise and other unpleasant things, if they are present in the source. This will happen largely for the reason that you will often find yourself quite close to the screen, on which at that moment there will be not your black shadow, but large pixels (after all, 1080p is not 4K). So I was happy to sit closer to the image, but I could have suffered from using low-quality recordings. With some films I found a combination of elevated black levels and analogue noise, which could be frustrating at low bitrates.

For some reason, having the EH-LS100 projector inspired me to rewatch a couple of episodes of Game of Thrones. And how I was pleased with the bright sunny scenes and the fine detailing. Those reflections of the water, the greenery, the tapestries on the wall, the candles... it was all perfect. The projector also helped me decide to finally watch the last part of the first Star Wars trilogy (yes, I didn’t watch it, and I’m almost not ashamed of it). Darth Vader's black helmet still appears black due to the reflections.

Power modes

The projector menu has an “Eco” tab in which you can select the operating mode of the light source. There are three standard modes + custom:

"Normal" mode. The projector operates at maximum brightness, in a quiet room the noise level will attract attention during quiet movie scenes, although it is easy to get used to.

Quiet mode(quiet). The noise is reduced by an order of magnitude, becoming almost unnoticeable, but the brightness drops to 66% of the maximum.

"Extended" mode(extended). The noise is the same as in the “Normal” mode, and the luminous flux drops to 61% of the maximum, extending the estimated life of the light source from 20 thousand hours to 30 thousand hours.

Custom mode(custom). Noise is the same as in “Normal” mode, but allows you to set any brightness between “70%” and “100%”. Although in fact it is not 70%, but 61% (as in the “Extended” mode).

In bright rooms, I always used the “normal” mode, but when viewing in the dark, you can select “quiet”.

It turns off in about 7 seconds, immediately reaching maximum brightness, and turns off instantly.

Epson EH-LS100 and games

Because the EH-LS100 wants to be seen in the light and allows you to sit closer to the screen, I've given it the honorary title of "gamers' friend." The lack of a “rainbow effect” and the ability to manually adjust the gamma to draw out the shadows when required are also influential. But the main thing is that you can put a table a couple of meters from the 120-inch screen and “plunge headlong”... Forgive me, but personally I plunged into Diablo 2 and Quake 2, because I’m an old person and it’s too late for me to do anything change. But you, young people, have everything ahead of you!

A lag of 56ms means a loss of 4 frames at 60 fps. This is fine for simulators and racing games, it's normal for most console games and even shooters (I played my Quake just fine and didn't feel any control lag). However, such a delay is unacceptable, for example, for professional Counter-Strike players.

If you have a steering wheel or joystick, then rejoice! The immersive effect is guaranteed. I tried Test Drive Unlimited and was very pleased.

Generally speaking, I rarely played anything in the dark, which also tells me that the EH-LS100 is a dream for the home console gamer.

Appearance and connectors

For users unfamiliar with ultra short throw projectors, the EH-LS100's appearance may be confusing. The power cord extends forward toward the screen, keeping it out of sight. The connector panel is located on the left rear of the projector when looking at the screen. The panel is covered with a removable cover that releases the wires downwards, after which the user can redirect them forward to the screen, to the side or back. There is a built-in control panel on the right side in case you lose the remote. In most cases, you'll likely only need the power button.

On the same side, slightly to the right, there is an air filter cover, under which there is a manual focusing lever for the lens. According to the instructions, the filter requires cleaning every 20 thousand hours, or earlier if the temperature indicator lights up. Alternatively, if the projector is operating in a very dusty environment, it is recommended to be conscious and clean the filter more often. Thus, the projector manufacturer claims that the filter resource is equal to the light source resource.

Next to the lens window are two sensors that detect interference in the light path near the lens. If you close them with your hand, the projector will start to “panic”, blinking all possible indicators (what will happen later - to be honest, I haven’t tried it). There is also an infrared sensor for the remote control. Since the user can only be on one side of the projector, there is no need for multiple IR sensors.

Concerning connector panels, then we have 3 HDMI inputs, one of which supports MHL, as well as VGA input and VGA output.

In addition there are two audio input(3.5mm minijacks). One of them is used to play sound when RCA video input is selected as the signal source or when playing a slideshow from a flash drive via USB Type A. The second audio input is used when VGA input is selected as the source. The audio output output sends audio input from the projector to external speakers. The EH-LS100 has a built-in 16-watt mono speaker, which is useful when you've moved into a new apartment and haven't yet moved your speaker system. But, to be honest, who will listen to the built-in sound, no matter how adequate it is?

Additional connectors include a connector for connecting to a wired local network(RJ45), as well as a separate USB-A connector for connecting an optional W-Fi module. It is curious that there is a wireless network indicator on the removable cover of the connector panel, but in fact it is a plastic window that lets in the indicator light of the USB module itself.

This way you can connect the projector to your local network, project to it using the iProjection app for PC (formerly EasyMP Multi PC Projection), project from mobile devices using the iProjection app (for Android and iOS), or monitor or control the projector over the network. The following are supported:

• Epson Projector Management Software (Windows)
• Alerts by email
• SNMP Management Protocol
• PJLink control protocol
• Crestron RoomView

But I have not yet talked about the remaining three USB connectors, although there is little new here:

• USB Type B allows you to transmit image and sound via a USB cable from a computer, or transmit signals from the projector remote control to the computer to allow you to control the presentation (cursor movement, page turning, etc.)
• 2x USB Type A are designed to connect flash drives (formatted in FAT16/32) for playing images or slideshows. No video.

As for the remote control, unfortunately, the projector is equipped with a standard Epson universal remote control, which is used in many home and office models. The remote control is high-quality, well-thought-out and compact, but over all these years it has become quite boring to me. On the other hand, a special remote control for a home projector, as a rule, differs primarily in its backlight, which in this case is not required.

Installation

Since we're on the subject of projecting from a computer, it's worth noting once again that the projector's resolution, 1920x1200 (WUXGA), is slightly larger vertically than Full HD - the aspect ratio is 16:10 instead of 16:9. For example, if you output a signal from a Blu-Ray player or, as I did, duplicate the desktop on a Full HD monitor and projector at the same time - in this case, the projector has a resolution of 1920x1080, not 1920x1200, so not all pixels are used - the top and thin empty stripes remain below. If you wish, you can force the projector to stretch the image in the Signal menu settings. In short, the projector displays both Full HD and WUXGA pixel-to-pixel resolutions.

On the bottom of the EH-LS100 there are three identical screw feet (two at the front and one at the back) that allow you to adjust the projector's sideways tilt. If necessary, the projector allows you to adjust the shape of the screen in the following ways:

• Correction of trapezius separately vertically and/or horizontally
• Correction of trapezium vertically + horizontally by dragging the corners of the image (Quick Corner)
• Correction of surface curvatures (Arc correction) - like Quick Corner, plus any line of the image border can be bent inward or outward. So, if you have a hemispherical wall, then there should be no problems. This type of geometry correction has memory slots - you can save different positions and then quickly switch between them.

And yet, unless you are organizing a museum installation, you will most likely prefer to preserve the original clarity of Full HD resolution and immediately install the projector at the correct angle to the screen or wall, since this is done easily and naturally.

As for the screen, my job is to warn you once again that a short-throw projector shining onto the screen from below will reveal all the folds or unevenness of the screen canvas, if any. This does not mean that a roll screen cannot be used (I used it), but it is highly advisable to use a screen with a tension system or a flat wall.

Projection distance: The EH-LS100 produces a 2.72-meter-wide image from about 40 cm from the front edge of the projector body (the lens itself is located another 34 cm further, at the rear of the projector. This image width corresponds to a 126-inch diagonal at WUXGA (16:10) resolution ) and 123 inches with Full HD resolution (16:9).

In this case, the surface on which the projector is installed must be lower than the bottom edge of the image by 48 cm (WUXGA resolution) or 56 cm (Full HD).

Thus, when projecting a WUXGA (16:10) resolution, the distance from the surface of the stand on which the projector stands to the bottom of the screen is approximately 27% of the image height. When projecting Full HD, this distance is about 36% of the image height.

We get a diagonal of 90 inches (16:9) with approximately 21 cm from the front edge of the projector to the screen (about 55 cm from the lens to the screen).

The throw ratio is 0.27:1 (distance divided by screen width), but that distance is measured from the lens rather than from the forward-facing front edge of the device.

I will also give the tables that I found in the American user manual:

1. Projection distance
2. Distance from the top of the projector to the bottom edge of the image
3. Distance from top of projector to top edge of image
4. The distance from the lens to the front edge of the projector is 34.9 cm

There are also holes on the bottom of the projector for wall mounting (not included); It is claimed that it can be projected onto a table, which will also require a special mount.

Sharpness

The EH-LS100 demonstrated very good sharpness both in the center and at all edges of the screen. This is an excellent result not only for a UCF projector, but also for many conventional long-focus projectors.

To achieve this result, you need to accurately and carefully adjust the focus, which, as I said, requires removing the air filter cover. However, nothing stopped me from changing the diagonal from 123 inches to 100 inches and back, moving the projector closer or further from the screen - no significant defocusing occurs. Therefore, I will say that the EH-LS100 can be moved quite freely.

There is a “detail enhancement” function in the image settings. This setting can be set in a position from 0 to 100. Starting from about 30, noticeable distortion of fonts begins, so I will not recommend setting a higher level. Up to this level, there is a smooth and gentle improvement in perceived detail without noticeable artifacts. This feature can be used when playing high bitrate videos, otherwise it may highlight image artifacts. In computer games, enabling this “improvement” can lead to increased latency.

Epson EH-LS100 color reproduction

You will be surprised, but the most accurate mode on the EH-LS100 is called “Game”. In situations where maximum shade accuracy is needed, you can use it, or the “Cinema” mode is a matter of taste. The Dynamic mode is good in a brightly lit room, but has its own inaccuracies, which may or may not be noticeable, depending on the content. If you don't like its color tones but still want more vibrancy, then try the Vivid Cinema mode, which increases the contrast of the image by brightening the colors.

Dynamic mode

It has a moderate blue tint, and there is a chance that the viewer will not notice it (unlike, say, green or yellow shades). Also, this blue-dominant tint will go a long way toward compensating for the warm (yellowish) light sources in the room when the lights are on. Thus, in this mode there is no predominance of green light, characteristic of the bright modes of lamp projectors.

Hue accuracy is also quite good when compared to the bright modes of other projectors, although there is some distortion that will be noticed by viewers with a trained eye:

• blue and green shades are brighter than red/red/crimson
• blue color is not saturated enough
• 100% yellow, green, purple colors are noticeably shifted in hue

In terms of color gamut, green is slightly different from standard sRGB green due to its greater saturation and yellowish tint. Otherwise, we can talk about a color gamut close to sRGB.

Gamma correction initially ranges from 1.9 to 2.1 in the shadows, which provides good shadow detail in the light, but emphasizes noise and artifacts in content with poor bitrates.

This mode is suitable for watching movies, but when viewing photos or animations, for example, you may prefer to use a more precise mode.

Color gamut and brightness error (colors 75%, 50%, 25% saturation) of colors in “Dynamic” mode

White balance and gamma in Dynamic mode

Vivid Cinema mode

It has a more subtle blue tint, and not blue-green, as in the “Dynamic” mode. The hue is constant for all brightness levels from 0% to 100%.

With more correct color tones than in the “Dynamic” mode, this mode is characterized by a significant increase in the brightness of all colors, especially with saturation of 25% and 50%, which helps combat background illumination, making the “Bright Cinema” mode more expressive in the light, than the more accurate Cinema mode.

However, gamma correction in this mode deviates even more from the standard than in Dynamic and its use is also a matter of personal preference.

White balance and gamma in Bright Cinema mode

Cinema Mode

It has an even less noticeable blue tint, which is also designed to combat warm lighting, and in neutral lighting it is not noticeable, since few people can distinguish bluish-gray from gray.

With the exception of black areas, gamma is rated at 2.1 and drops to 1.8 in dark areas, helping to distinguish shadow detail (but also all sorts of noise in poor content). If you select "-1" in the gamma settings, the indicator will be 2.3.

Colors are more accurate than in Vivid Cinema mode and are not specifically enhanced, making images appear washed out in a bright room. In the dark, this mode is preferable.

Color gamut and brightness error (colors 75%, 50%, 25% saturation) of colors in Cinema mode

White balance and gamma in Cinema mode

Game mode

The most accurate mode. White balance is accurate and neutral, gamma 2.1. All colors that in other modes went beyond the sRGB range are firmly driven into the correct frames and sit neatly on the border. The 100% blue and 100% green colors cause minor complaints, but 75% blue and 75% green are already strictly in place.

The mode is accurate and holds up when running through ColorChecker, ultimately delivering an average Delta E (CIE94) of 2.85 (across 89 shades). This is good even for a home theater projector.

There are full tools for correcting white balance and RGBCMY (individual colors). After playing around with blue and red a bit, I lowered the average Delta E to 2.13. And this is not the limit (although who needs that?).

However, in bright rooms I still prefer the Dynamic and Vivid Cinema modes, and such minor deviations do not mean anything there. And yet, in the right hands, the color management system can certainly improve even the bright modes. For example, the EH-LS100 projector, alas, tends, like all other projectors in bright modes, to cut off shades at the top of bright colors (for example, when 90% red is no different from 100% red). This can be compensated for by reducing the level of the standard “contrast” image setting, but then we will also cut off the top white color, which is fine with the development of bright shades.

Therefore, it is better to restore detail to about 100% brightness in individual colors using a color management system, reducing the brightness for each color until the shades are restored. This is just an example of how it can be used. Please note that the color brightness should not drop.

conclusions

The Epson EH-LS100 excels as a home entertainment projector and TV replacement. It represents a fairly new class of devices, even for me, and is intended for people who would like to watch their content on a large screen with low to medium illumination, getting the maximum viewing experience. Under these conditions, the EH-LS100's brightness, comparable to entry-level installation projectors, will provide noticeably better image quality than any home theater projector with brightness less than 3,000 lumens. The actual brightness of the EH-LS100 is noticeably higher than stated, while it claims an ultra-long laser life and an excellent warranty period.

Combined with instant on/off operation and short throw optics that eliminate restrictions on room movement and seating positioning, the EH-LS100 is the ideal choice for bringing any wall to life as a screen. And not on a dull screen with faded colors, as sometimes happens. Of course, you can't expect to get this entire package for a price comparable to entry-level projectors.

In addition to what has been said - good color rendition and no “rainbow effect”. Whether you're watching movies, sports, animation or playing games, you'll be impressed by this projector's performance in low light, with superb colors simply due to its honest high brightness.

However, this projector is not intended for dark rooms. In the dark, the EH-LS100 will produce images that are noticeably less contrasty than you'd expect from this price segment. Those who judge this model by the criteria of a regular home projector or home theater projector are making a mistake.

The goal of this model is to preserve not only impressive bright colors in high light conditions, but also mid-tones, such as skin tones, that will be no worse than when viewed in the dark on regular home projectors. The EH-LS100 eliminates background light damage where other projectors would lose image clarity. But, alas, you can’t expect black depth for obvious reasons, although there is a lot of content where it is not required.

And yet, the EH-LS100 conveys scenes such as a city at night well thanks to the contrast of darkness and bright lights - this applies to both movies and all kinds of toys (for example, racing). Speaking of gaming, the projector will be very appealing to casual gamers, but its latency is too high for a Counter-Strike tournament.

The lack of support for 3D mode is also regrettable.

Well, in general, the Epson EH-LS100 is an extremely successful, fun and unusual product. I highly recommend it to anyone who will use it for its intended purpose!

Ultra short throw, short throw and long throw projectors are the three main categories into which multimedia devices can be broken down. Their main difference from each other is the size of the distance between the projector and the image plane. Each type of device has its own niche and area of ​​application. Long throw projectors are classics, they appeared first, have a simpler technological solution and are used today mainly in large halls and cinemas. Short-throw devices are used more often in offices, at presentations, and finally, ultra-short-throw devices, which will be discussed in this article, are convenient in apartments or in small educational or office spaces.

Ultra short throw projectors: types, advantages, scope of application

What are the benefits of ultra- and short-throw projectors?

• Located close to the screen, which eliminates long cables and simplifies the installation process
• Allows you to achieve widescreen images in a small room (cinema effect).
• During the demonstration of the image, the luminous flux from the projector does not blind the audience and the speaker, and no shadows are formed from the teacher or those sitting in the hall on the screen.

The difference between an ultra-short throw projector and a short throw one is in the projection ratio. Throw ratio (or throw ratio) is the ratio of the distance between the screen and the projector to the width of the screen. If for a short-focus lens its value is 0.5-1.5, then for a second one it is less than 0.5, which allows you to get a diagonal image size of up to two meters from a distance of less than half a meter.

Reviews from teachers and speakers about the use of these projectors are enthusiastic, since the process of installing the projector has been simplified, no special technical skills or invited installation specialists are required, and conducting lectures and reports has become much more convenient and efficient.

Lens-mirror

Ultrashort throw projectors, in turn, are divided into two types: lens and lens-mirror. Lens-mirror is a new word in the development of projection technology. They are equipped with a special optical system consisting of a lens and a mirror. The light flux from the lens is directed not directly at the screen, but at the mirror, and from there the reflected image hits the screen. In this way, it is possible to reduce the projection distance to tens of centimeters. Classic lens models have less weight, but work from a greater distance to the screen. It is easier to install such projectors, since, as a rule, they come with a mounting rod and are mounted on the same wall as the screen. This is also a plus, since problems often arise with attaching the projector to the ceiling in rooms with high heights.

Features of operation of lens-mirror projectors

It should be noted that the use of ultra-short throw projectors places increased demands on the screen surface. Since the light flux falls on the reflective surface at an acute angle, unevenness and roughness of the screen create shadows and glare, which affects the image quality. Therefore, it is necessary to use screens with a white or matte smooth surface. We must pay tribute to the developers of ultra-short throw projectors; they had to deal with uneven illumination of the screen (due to the acute angle of incidence of the light flux, the edges of the screen farthest from the lens were illuminated with less brightness). It was necessary to use non-standard software and hardware solutions, including the use of free-form objective lenses calculated using complex programs. With the advent of projectors with such a small throw ratio, their scope of application has expanded, including for advertising purposes. For example, in shops and markets where space is limited, advertising of services and goods has become possible.

Ultra short throw laser projectors

Laser projectors are a new branch of development of projection technology. Unlike classic ones, the light source in them is a laser emitter, and not a mercury lamp or LED. The advantage of this technology is that there are no requirements for the reflection surface, there is no loss of clarity, no defocusing even on an uneven surface. The principle of obtaining an image is similar to the method of obtaining an image in ancient cathode ray tubes. The laser beam scans the surface 50 times per second and forms an image as a single unit.

Advantages and prospects of a laser projector

Advantages of a laser projector:

• long service life of the laser source up to 20,000 hours versus 3000-5000 for the lamp;
• consumes little energy and operates quietly as it does not require cooling;
• does not require time to warm up and cool down, instantly turns on and reaches maximum brightness and turns off at the same moment;
• can create images on huge screens several tens of meters long;
• high contrast, creates a perfectly black color, which is impossible in lamp projectors;
• since it does not have a lens, from 30-40 centimeters it can produce a large image of up to two meters.

Disadvantages of a laser projector:

• still very high cost;
• heavier than lamp projectors.

According to experts, the future lies with laser projectors, since due to technological advantages it is possible to unlimitedly increase the brightness of the light flux and the clarity of image detail.

Interactive projectors improve learning efficiency

Ultra-short throw interactive projectors make the learning process extremely convenient, interesting and productive. The interactive capabilities of devices today are found everywhere in life - first of all, our smartphones, screens in cars, terminals for accepting payments, etc. Of course, projector manufacturers could not help but give them interactive capabilities. The first to appear were ultra-short throw projector kits with a board. The kit consists of the projector itself, fasteners, an interactive whiteboard that determines the coordinates of touching the surface, and software that controls interactive functions. The device transmits an image from the computer to the board, which, using built-in sensors, transmits the location of the stylus or finger back to the computer. The boards vary in size and type of sensors, and their price depends on this. Optimal in terms of price/quality ratio are optical boards measuring 2.08 meters.

A more modern and advanced solution is interactive short-throw projectors. They already have built-in interactive capabilities. The projector's built-in infrared radiation makes any surface interactive, eliminating the need for an interactive whiteboard.

According to reviews from teachers, the interactive learning process is extremely convenient for both the teacher and the student. Everything is clear, the lecture or lesson ends up in students’ laptops along with the notes made during the lesson.

LED projectors: advantages and disadvantages

The main difference between ultra-short throw and others is that the light source in it is not an ordinary lamp, but LEDs. LEDs emit light, and a DLP micromirror matrix forms the image. Since the matrix and LEDs are miniature, the device is compact and light in weight.

Advantages of an ultra short throw LED projector:

• light weight and size. There are low-power projectors the size of a pack of cigarettes;
• low power consumption, since LEDs consume energy 7-8 times less than lamps;
• long service life of LEDs, 5-10 times longer than lamps.

There is one and very important drawback - the low luminous flux is no more than 2000 lumens, which means it can only be used in dark rooms.

For home use, such a projector is quite suitable, but for business trips, due to its miniature size and light weight, it is very tempting to use.

Epson projectors are leaders in the global multimedia industry

Epson ultra-short throw projectors are part of a large line of projectors from this Japanese corporation. Seiko Epson was the first company in the world to release the device in 1989. Since 2001, she has been the undisputed leader in this industry. It has the widest range of projectors among competitors for any task and different price categories. Epson ultra-short throw projectors in education are used to create interactive classrooms in higher and secondary educational institutions. And in this segment, Epson is a trendsetter and a leader in innovation.

Epson's modern line of ultra-short throw projectors includes the following models: Epson EB-595Wi, EB-675W, EB-675Wi, EB-680W, EB-680Wi, EB-696Ui and others. Since these projectors are used in education, i.e., as a rule, in bright rooms, one of the requirements is the brightness of the light flux. All presented models are very powerful: 3200-3500 lumens.

The younger model Epson EB-595Wi has the following main characteristics:

• very short projection distance (44 cm) on the screen - 190 cm;
• high contrast - 14,000:1;
• luminous flux brightness - 3200 lumens;
• very high lamp life - 10,000 hours;
• resolution WXGA (1280x800);
• interactive image on any surface.

By marking the model you can find out some of its characteristics. For example, the letter i indicates that this model is interactive, the letter W is the resolution WXGA (1280x800), U is WUXGA (1920x1200).

- the best among gaming and home models

LG needs no introduction. Among the variety of equipment offered by the company on the world market, LG ultra-short throw projectors stand out. The company is not a world leader in the production of these devices, like Epson Corporation. But it has captured leadership in the home and gaming segments, as well as in the LED projector market. One of the new products in this segment is the ultra-short throw projector LG PH450UG-GL.

This amazing model has the following characteristics:

• from a distance of 33 cm an image of 2 meters is formed;
• wireless connection - video is transmitted via Wi-Fi, sound - via Bluetooth, 2.5 hours can be operated on batteries;
• weight - 1.1 kg;
• brightness - 450 lumens.

Full HD is the required standard for projector image quality

Projectors used at home as home theaters must display high-quality content, and in the coming years this will be the Full HD standard with a resolution of 1920x1080 pixels. In this regard, ultra-short throw Full HD projectors have begun to enter the market, although the price is still high. Among the released models are the following projectors - the one mentioned above in the article LG PH450UG-GL, LG PH1000U, Optoma EH319UST, Optoma EH320UST, Epson EH-LS100, etc. The listed models differ in price, characteristics, and method of image production. LG are the most LED, they are low-power, inexpensive (just over 40,000 rubles), but at home, where you can reduce the illumination of the room, they will suit the audience quite well. Optoma mid-price category, lamp, quite powerful 3000 lm, price - 120,000-150,000 rubles. And finally, Epson is the most expensive model - 250,000 rubles, laser, very powerful, with a brightness of 4000 lm. All the presented projectors, especially the last one, are a real alternative to huge TVs, and, according to reviews from experts and users, such devices are the future.
