Then Texas Instruments released an 0.66" 4K UHD chip with a physical mirror matrix of 2716 x 1528 which uses two-phase pixel shifting to create 8.3 million pixels, which is 4K UHD. Since we are not relying on native 4k resolution, I am asking will the pixel shifting technology manipulate my 1080 youtube video into looking like 4K? Thanks for this article, I am staying at 1080p for a few more years. Then, before it reaches the projector lens, the images apparent resolution is boosted using so-called pixel-shifting technology. With an HD 1080p source, we no longer have the extreme detail in the source itself. What is questionable is the life of the XPR module, aside from the noise it makes. At the opposite end of the spectrum are the tech liberals who believe that if the projector takes a 4K signal and does something to make it look like an exciting, high resolution 4K picture on the screen, that is really what it's all about. If I couldn't afford a native 4K projector--and I can't--I'd be absolutely delighted to spend my days being full of horse malarkey and enjoy the benefits of 4K HDR content on a pixel-shifting projectorwhich I do. True 4K, provided color and contrast are of similar high quality is still a different and better beast. There are projection applications that WILL benefit very directly from native 4K resolution devices. Both projectors are upscaling a 1920 x 1080 signal to a 4K-like image. HDR in particular does have the potential to alter the viewing experience for the better, though more so with high-light-output flatpanel TVs than with projectors, which do indeed struggle with hitting the highlights in an impactful way. Manufacturers are therefore able to apply the 4K UHD resolution label to devices that dont have this pixel count on their display panel but do have it on the screen. Thanks again. What happens is that the projectors internal scaling converts the input signal, whether 1080p or something less, to 4K and then applies that converted 4K signal to the pixel shifting process. The point at which this occurs depends on the contrast of the subject matter, but with the 4K HDR movie Lucy it appears to happen at a viewing distance of about 1.3x the screen width (with my 20/20 vision).
In the end, as we go about categorizing and defining these products, the practical question is what makes a 4K projector 4K? 
The bottom line is if you're happy with the large home theater image you have regardless of tech, who cares. In this no-man's land, where the latent competitive strengths of both projectors are visible simultaneously in the same picture. projector native Its also judgement as to what you deem as acceptable in terms of the price gap between the native and non-native 4K projectors. Yes, the PX727-4K is the sharper of the two. Are these different technologies from native 4K?Those selling you the latest tech dont always take the time to explain the difference between these terms and how this difference affects your purchase decisions. The VW285ES's pixel structure is so small as to be almost invisible, but on very close examination you can detect the pixel pattern. So these two models compete directly both in resolution class and price. So as your move back your perception flips and the Epson 4000 looks like the sharper of the two projectors. sxrd vpl gtz380

This is simply not the case. The ViewSonic PX727-4K has the 0.47" DLP chip with a 1920 x 1080 mirror matrix, generating a 4K picture (8.3 million pixels) via four-phase pixel shift. I've never had a 1080p projector with this problem why do the uhd dlp's have this, makes me wonder if we are getting a uhd picture made from less than the chip can produce. The big question is, can you see the difference between a projector using authentic native 4096 x 2160 resolution chips, and a projector using two-phase pixel shifting on a native 2716 x 1528 chip? Dont the mirrors move and pixel on/ off color changes have to fire 4 times more than a native 1 to 1? Thats QUITE a twist on what the article was saying. Buttrue 4K is still a different animal than Faux-K. Pixel shifting technology is clearly a leap over straight 1080p. Meanwhile, the Epson HC 4000 uses 3LCD chips with the same 1920 x 1080 pixel matrix, but it has only a two-phase pixel shift. When you see a similar image, but one taken with a camera of lower quality, even if you can't discern pixels, there is no question as to which picture has more real data and more information. 720p to 4K conversion (as you might experience coming from a cable box on certain channels) is more complex and not always quite as clean, though most set-top boxes will perform a conversion from 720p to 1080i or 1080p before sending it to the display -- probably with worse results than if you let the display do it. 
And yet, even with tiny pixels and huge PPI numbers, the higher resolution photograph is obviously superior and anyone can tell that there is more information. Take for instance cheap plastic lense used in expensive 4K Sony projectors. Good informative post Evan. Native 4K projectors are not cheap, theres simply no getting around that. Rob - I agree with your comment above. Anyone in the projector biz could tell at a glance just from looking at pictures on the screen what the native resolution of the projector was. Once again, we start by doing some pixel-peeping close up, from a distance of 12 inches on a 5-foot wide screen. It seems like it's become vogue to think one more 'in the know' if you bag on 4K and start touting the virtues of other things because it makes you sound like you have some kind of hidden knowledge that the masses aren't privy too. But to call it a "con game"or a "game" at allis uninformed and arrogant. The difference here is that native 4K projectors have roughly eight million distinct pixels on their panel to start off with, while pixel shifting tech starts with a lower number of pixels and creates the higher number by using the source image and processing it.Depending on the individual model, some projectors pixel shift twice, some do so four times with the former having a more convincing 4K effect in areas of the image where their is finite detail such as small text.Weve made no bones about the fact that this is not native 4K. And as we know, high contrast makes a picture look sharper. Subscribe now to never miss a thing from ProjectorCentral.com! Yet if you're looking at such images on anything other than an actual print, you are looking at a finite number of pixels equal only to what any given display can reproduce. When you consider you can get a 4K enhanced projector such as theBenQ W2700 for as little as 1360 compared to the native 4K UHD starting point of 5,000, you can see why this option has gained so much attention. As with any new development in technology, theres a whole load of jargon associated with 4K projection which, unless youre a tech expert, can often be quite difficult to understand.Whats the difference between 4K DCI and UHD? Now that doesn't mean that a projector with superior contrast or more accurate color won't be deemed superior in overall enjoyment. As with any new development in technology, theres a whole load of jargon associated with 4K projection which, unless youre a tech expert, can often be quite difficult to understand. The two-phase shift in this implementation tends to blur any hint of a discrete pixel matrix. projector disadvantages uhl55 optoma projectors The short answer is yes, you will enjoy enhanced detail with 1080p content on one of these 4K-friendly projectors. Thanks for the reply Robin. On the UHD50, when you are at the same distance of 12 inches from a 5-foot wide screen, you can detect an extremely subtle hint of pixel structure, but it is nowhere near as distinct as on the UHD60. So the HC 4000 paints two slightly offset 1920 x 1080 images per frame while the PX727-4K paints four. Viewing the pictures close up, at a distance of 12 inches from a 5-foot wide image, you can see an obvious difference in pixel structure. "Different manufacturers implement this technology in slightly different ways, but for a very rudimentary explanation of the tech it essentially overlays two HD images on top of each other (depending on the projector's panel/chip), shifted by a half a pixel up, down, left or right quickly so the naked eye cant detect the shifting. But pixel-shifting is entirely different, and I look at the image my Epson 5040UB puts out when given 4K Source material, and it is stunning and elegant, and I just couldn't imagine it being any perceptibly sharper. Different manufacturers use different terminology to describe this technology. Let's now consider the display of an HD 1080p picture rather than 4K HDR. Once you move to a viewing distance beyond 1.0x the screen width, the eye's ability to resolve the subtle differences in detail between these two projectors evaporates. 
But according to the Consumer Electronics Association (CEA), a projector being described as 4K UHD must have at least one HDMI input that can accept a native 4K UHD signal, and be capable of. It has been reduced in size and its "noticeability" in the most recent generation of chips, but it's a reality for all single chip 4K DLPs as far as I know, at least those using the 0.47-inch DMD. But every 4K projector you buy will end up scaling up to 4K to fill out its pixel count with a 1080p signal, whether it's a native 4K JVC or Sony, a full-4K DLP projector that does pixel-shifting, or an Epson with 1080p chips that doubles the pixels with Epson's enhancement. I don't think politicizing tech by using fundamentalist and tech liberal is helpful at all. There are other contributing factors on a projector that affect what you perceive as image sharpness. 
The chip's physical resolution, at least in the home theater world, has become irrelevant. Thus, in theory, if the number and size of discrete pixels has anything to do with it, the VW285ES should be able to resolve more detail than the UHZ65, assuming the three chips on the VW285ES are perfectly aligned. 
So the VW285ES looks subjectively sharper and more three dimensional despite the fact that there really is no additional detail in the picture. True 4K sneaks into quite a few product descriptions, while the list below outlines some of the brand-specific terms:BenQ: XPR TechnologyOptoma: XPR TechnologyEpson: 4K enhancementJVC: eShift5While the marketing terminology is contentious, the technology and price point behind pixel-shifting 4K resolution projectors deserve recognition. But there is also objective reality. Thanks for taking the time to share your insights and clearing up this (potentially) confusing topic for many. It is a terrific technology that is hard not to love once you see it. And it always looks better than native 1080p would. Freephone 0800 073 0833, Projectorpoint 2022 all rights reserved, Top 7 Laser Projectors For Businesses 2022, Best Meeting Room Laser Projectors For 2022, Why Choose 4K Resolution Displays For Your Business, Choosing The Right Size Display For Your Meeting Room. Different manufacturers use different terminology to describe this technology. Now, let's back up to a more practical viewing distance. udx uhd 4k22 lumen However, with HD 1080p we once again encounter a big difference in contrast, except this time the VW285ES wins. 
Thanks for your comments, Felix. Move up close, however, and you can see pixel structure.A picture generated by either the 4K DLP chip or by the 3LCD 4K-enhanced models will certainly appear higher in resolution than a standard HD 1080p picture from a distance of 1.3x the screen width. Partial frames from the lower resolution panels are minutely displaced by a rapidly-moving shifting device. projectors shift In this movie there are definitely certain elements in some scenes which are rendered with slightly more detail on the VW285ES. These partial frames are projected in quick succession, building up an on-screen image with a 4K UHD pixel count.The video highlights the benefit of native over upscaled. Excellent, thanks! You get the same results if you compare them at any size when maintaining the same ratio of viewing distance. jvc projector 8k shift The revolutionary technology of pixel-shifting has injected a lot of controversy and confusion into the world of 4K projectors. While I prefer the latter definition myself, what I care more about is that buyers come to realize that the differences in detail resolution between all of these various 4K implementations are extremely trivial compared to the major issues of contrast, brightness, color balance and saturation, and image stability and clarity that ultimately define the greatness of a home theater picture. Ive been leaning towards the Optoma UHZ65, but has anyone actually played games on this sucker? 
Faux-K is great. Let's put these two projectors side by side and take a close look. Though many folks use the term faux-K as simply synonymous with pixel-shifting technology without implying anything derisive, many use it precisely because it insinuates inferiority. There is source resolution and there is pixel resolution. I reckon it should be a spec of the projectors so when we use your site's screen calculator ( been using for years!
In this case the UHD60 is higher in contrast than the UHD50, and in many scenes this contributes to the perception of it being the sharper of the two projectors. Fortunately, the 1080-line to 2160-line conversion on most TVs and projectors today is excellent, aided by the fact that it's a simple doubling. Different manufacturers implement this technology in slightly different ways, but for a very rudimentary explanation of the tech it essentially overlays two HD images on top of each other (depending on the projectors panel / chip), shifted by a half a pixel up, down, left or right quickly so the naked eye cant detect the shifting.The display panel, therefore, can be native 1080p (as seen in 3LCD and some entry level DLP models), Some DLP models might use a chipset using 2176x1528 micromirrors, the device projects the same pixels twice, thus creating twice as many pixels on the screen resulting in a crisper image. This is a a great write up but I question the use of a small 5 foot screen. Let the buyers and sellers beware! Time and time again weve been surprised by new models and the seriously impressive images they can achieve. The 5' images in this test were used simply for comparative evaluation of the projectors when they are both projecting the same size image.
Contrast (and other factors like digital noise, lens resolution, and video processing) become the determining factors in one's perception of the picture's overall sharpness. Evan, Fantastic real world review. I know that we are limited on any 8K media, but having the equipment now only will keep disc media alive because there is no way they can stream this yet and 4K up sampled to 8K would be excellent. In this regard it is extremely similar to the PX727-4K. Got your head around the resolution terminology? Though as previously noted, theyre less subtle with high-resolution graphics and text.
Contrast is king. This article is terribly one side and doesn't mention any of the negative side effects of image shift like the shimmer and artifacting you can see when there's a ton of motion on screen. Its often beyond the ability of the human eye to resolve such minute levels of detail. But also the level of digital noise, the image enhancement video processing, the color balance and saturation, and the optical precision of the projector's lens, all contribute to making a 4K projector's picture great or less than great. It's well organized, well written, objective, and well supported with concrete examples. lightest projectors Once you back up to a viewing distance of two feet from a 5-foot wide screen (that is, 0.4x the screen width and a lot closer to the screen than anyone would want to be when watching a movie), all hint of visible pixel structure disappears on both projectors. Please call for details. That said, resolution is indeed a very critical aspect of the front projection experience given the larger screen size. Back in the day, the native resolution of a projector was a big deal, and rightly so. Ive seen no such projector that is 1080p look like a 4K image.
But as always it comes down to the overall optical path. Let me be more specific, would all the 1080P videos that I am used to watching on my epson 1060 appear to be more crisp and be automatically enhanced? 
When viewed very close up they look not quite perfectly identical as far as the indistinct pixel array is concerned, but they are pretty darned similar. In reality, pixel shifting has produced rapid advances in picture resolution at prices far lower than you must pay for projectors that have native resolution 4K chips. They most certainly can be. The minimum HDMI cable size you need to deliver basic 4K, therefore, is a 10.2Gbps cable. projectors Better comparison would be to use a much larger screen 10ft, or so . It is not surprising that the PX727-4K can deliver more 4K detail from a 4K signal, but it is surprising (to me anyway) that it can even upscale HD 1080p with a higher apparent level of precision. The lens on Sony projectors has been well known as a limiting factor in transmitting true 4K resolution in the lower models. 
Its all down to your individual perception of value and how much 4K content youre watching. And this is a huge however - the Epson HC 4000 is much higher in contrast with much more solid black levels than the PX727-4K. With these two projectors, with respect to detail definition itself, there is very little if any discernable difference between the two pictures, even when viewed close up. Weve brought this guide together to help you do just that. jvc nx7 lcos Once we've put the 4K material on the screen, the issue then becomes whether there is a level of fine detail that can be resolved by the VW285ES that cannot by the UHZ645, and whether this incrementally resolved detail is visible to the viewer at a typical viewing distance. This occurs in the first scene, where detail in the straw hat and the subtle texture of the leather jacket are more successfully resolved by the VW285ES. Even the JVC and Epson models with their simple two-phase shift on 1080p chips can outperform competing 4K projectors on the basis of contrast and black levels and produce pictures that look equal to, and in some cases better than, a competing 4K projector at a similar price. Optoma - I wonder if the differences between the phases affects refresh rates in the various 4K formats like 60hz etc and if it impacts input lag in anyway?

There is no sense of discrete individual pixels. dla 4k jvc projector ila x5000 x9000 lineup projectors resolution eu contrast ratio :). If you want to get the most out of your projector, take a moment to wrap your head around the different ramifications of this jargon dense as it might be. HOWEVER. Whether it is true 4K or faux-K has nothing to do with it. projectors Any conclusions reached based upon the number of discrete elements in the panels are erroneous, For the person talking about 110" screens, you're right, 4K is not for you. And has been a god send) You could calculate how far the light overspill would be. And the simple fact is this: we can no longer glance at an image on the screen and know the physical resolution the chips in the projector like we could before. I appreciate the thoroughness and the acknowledgement that not everything involving picture quality is about the number of pixels. Thanks for the article. The writer's conclusion -- that the differences in perceived detail are fairly minimal -- suggests that buyers are free to focus more on other factors that will improve the image quality (higher rated contrast, better rendering of HDR for example) or improve the set-up or user experience (powered lens functions, etc.). jvc projectors dla contrast lumens ratio shift 4k 1200 A screen of reasonable size with a standard black felt frame will usually hide it, but if you project on a wall or maybe have a screen with a fine bezel it's just there. I think may people will agree that resolution was the first but not necessarily the most impactful feature of the UHD format. 
Depending on the individual model, some projectors pixel shift twice, some do so four times with the former having a more convincing 4K effect in areas of the image where their is finite detail such as small text. 
Understood-people have complained about it for years, but the alternative would be to go with a more current 4K DLP where it's not as obvious or a 4K three chip projector. At this point the physical resolution of the chips in these two models has nothing to do with perceived image sharpness.
