So for people saying I'm hating on 8K TVs because I can't afford one, you seriously need to watch this: kzbin.info/www/bejne/fIfUi3RvnruHgLM It's an amazing example of how quality of TV technology is far more important than the quantity of pixels.

[@Oldschoolgamerdad]

I have a 75" 4k q9fn TV and except the hdr effect I don't notice any difference on the 4k and 1080p bluray versions (yes I do see it when I go very close but not where I sit). Another things is if I compare my C8 55" oled to my 50" krp 500m plasma with 4k vs 1080p bluray, the plasma TV will look sharper in motion and same results when next to the Q9fn. So my conclusion is if you have a good 1080p source it's enough for home tvs. We also did the same test at my brother place with projector, there we do notice that 1080p is not enough vs the 4k version but that's on 100". So I think as you say it is the cinemas that will benefit from 8/16k. 4k on home projectors and imo 1080p on TVs 75" and smaller. Even good source 720p looks great on small 50" TVs. And I'm a nerd on picture and sound quality but I also refuse to be fooled by the TV industry trying to force useless over expensive tech on consumers lol. Great video btw

[@drevel23]

I'm pretty sure I saw a video made by you years ago about 4K I may be wrong but I swear I remember something like that

[@cristic767]

It is not about the resolution "as is" but the resolution "as depending also the size of the screen". It's like in print or like in the mobile phones: "effective resolution", which is measured in ppi (points per inch) or dpi (dots per inch). I work in print, and for the printing industry, 300dpi is the standard for press. If we print big size banners we can lower that, depending on the distance you view the banner. A banner on a big building is printed at 30dpi. So, 8K TV... depending on the screen size and the room. You might need it, you might see very clearly the difference between 1080p and 4 or 8K. :)

[@Bronze_Age_Sea_Person]

I've heard somewhere that the resolution of our own eyes is somewhere around 8K. if that's true, depending on distance from the screen, going beyond 8K would be pointless. It would be good if we reach the limit, so we gamers stop focusing so much in graphics and give focus to technologies which aren't mature enough, like AI, for devs and hardware manufacturers to change their focus. Imagine a chip with built-in neural networks at a nano level, with trillions of nodes and connections. It would make youtube's AI trash in comparison.

[@csmarkham]

100% correct! If your eyes don’t change, and the distance from the screen doesn’t change, then the “K” going up gives you the most benefit if the screen size is also increasing. If you can see dots with whatever you have, getting the same _size_ at a higher “K” will make it seem crisper, more detailed,and smoother. Making it bigger at the same time and you‘ll have about the same experience as before, only bigger. Probably meaning your eyes will be darting around the screen and missing detail elsewhere. This is the _exact_ same experience as sitting closer to a smaller screen without changing the “K” # of pixels. All these numbers don’t matter. Just distance, size and resolution, or, “K”.

At 47", you can definitely tell the difference in quality between 1080p and 4k resolution. But it also depends on the distance you are away from the TV. I think the minimum resolution for various TV sizes are as follow: Up to 32": At least 720p Up to 55": At least 1080p 55" and above: At least 4k

I'm so excited for 4K to become the standard in gaming, since beyond that point you really won't be able to see the pixels.

[@AlexRoseGames]

only on a 42 inch tv. from 10 feet away on a 50 inch the average person can already see pixels on a 4k tv. 46 inches is where they start to become visible. Anything over 95 inches from 10 feet away will also be visible even at 8k, once you go above 95 inches you need 16k for perfect fluidity. or if you sit closer to the screen, say 6 feet, 30 inches is the cutoff for needing 8k and 66 inches is the cutoff for 16k if you game on desktop with your computer monitor 3 feet away, even a 30 inch monitor you can able to tell the difference between 8k and 16k. 4k is only a perfect density for 16 inch screens or lower at that distance. e.g. a 15 inch laptop screen, 4k is ideal

Yeah but anything is Retina if you are far enough away. 8k on TVs is a waste as chances are you will sit further back if you get a TV over a specific size. Say you sit 2 meters away, like I do, well 4k is retina until you get to about a 140 inch TV. I had a 32 inch 1080p and got a 55 inch 4k a few days ago and sitting 2 meters away I cant see a difference in quality but its big enough to see now and i would have noticed a difference if i bought a 55 inch 1080p instead of this 4k one. As size gets bigger, resolution should but 4k is already so dense it makes 8k almost completely pointless and anything above will be 100% pointless.

@robeat94 I mean, you can use a TV as a monitor and vice versa, but that's not what this is about.

High resolution monitors and non-consumer displays/TVs definitely have their place.

[@it_was_my_cat]

Actually, PPI doesn't mean anything. It depends more on how many pixels there are per degree in your field of view, which relies on screen size, resolution, AND distance to the screen. It's why a cinema screen can look great even though it has a terribly low PPI count.

It depends on the screen size and how far you view the screen from. People have been using 40-60 inch TVs as computer monitors when they were 1080p, with a much shorter distance than you are considering the average DPI of using 1080 as a monitor does not look great for reading normal text documents but still decent for video games and movies.

Yeah distance and screen size are by far the most important factors.

But that is exciting because once 8K becomes the standard, then there will more motivation to focus on improving the panels and the form factors of the TVs rather than increasing pixel count.

There is a use for higher resolutions. It allows us to make bigger screens and for the observer to sit closer to those screens without being able to distinguish individual pixels. So, if you have the same size screen, one in 1080 and one in 4k, there is a distance away from the screens that you can't tell the difference and you 4k becomes useless. However, if you get closer to the screen past that point the 1080p screen will start to lose clarity while the 4k still looks sharp. It's all about screen size and distance to the observer.

[@sdemosi]

Netflix did some studies that showed HDR at 1080p was more satisfying to viewers than 4k, for typical 55 inch tvs. My 2c on this is that people now buy bigger tvs for smaller rooms and hence they can actually tell the difference between 4k and regular 1080p HD on 65 inch tvs and sometimes on 55 inch tvs. There's also the difference of image processing. The newer tvs make better choices about how to upscale a 720 or 1080 image to a 4k screen. I have 2 OLEDs from Sony and LG. The Sony and LG OLEDs have AI which uses a machine learning model to create the optimum up scaling. However no upscaling is perfect and if you look very carefully you could get artifacts in the image that indicate where maybe the choice wasn't ideal based on human vision. A 4k broadcast which was captured from 4k or higher material won't have upscaling artifacts. It should look more natural. Throw in HDR and the colour reproduction will be more realistic. It's a double win but not quite perfect. The latest OLEDs look so good because the match natural colour reproduction (sometimes pushed to be more vivid on the LG tbh) with 4k resolution and very high contrast possibilities. The black levels are much more realistic and the overall impression is more immersive and less like watching a screen. The machine learning even does object recognition and can make adjustments to neighbouring pixel contrast ratios to create more realistic depth of field. My missus thinks that with default settings the LG is more impressionistic whereas the Sony is more natural but you can tweak either to make the image more of less vivid.

[@4rzaluz]

There shouldn't be any difference regarding pixel count.. as the ideal viewing distance would be around 30° from the top of your nose to the lateral boarders of the display..

[@keith6706]

They said this when screen sizes of the average TV and desktop monitor were much smaller. The American broadcast networks went to 1080 in the 1998-99 period. The average LCD TV at that time in the United States was 24 inches. At that size, there's no significant difference between 720 and 1080 for average viewing distances for TVs. The consumer 4K standard was set in 2012. At that point, average TV size was 38 inches, and no significant difference between 1080 and 4K at that size for average TV viewing distances. Let's use a 42 inch screen, since that's a pretty standard size. A 42" 16x9 screen has actual dimensions of 36.5 x 20.5 inches, giving, at 1080 resolution, a pixel size of about 0.019 inches. If you're sitting 8 feet away from a TV of that size (not unreasonable), each pixel would have a visual angle of 0.0113 degrees. At 6' feet away, 0.0151 degrees. The problem is, a person with 20/20 vision has, at that distance, a visual acuity of only 0.0167 degrees. This means that a 1080 42" TV at 6 feet away is, essentially, at the limit of human resolution for that person. If you had a series of alternating fixed black and while lines on that TV screen each a single pixel wide, it would be _just_ detectable that it's a series of lines and not simply a solid gray screen. If you doubled the resolution (to basically 4K), each pixel would be, at 6" away on that same size screen, 0.0075 degrees, which is impossible for a human at that distance to make out. The series of alternating lines would just be flat gray. The only way you'd get the detail back would be to double the size of the lines...which is taking you back to 1080. And this is before taking into account image movement which TV usually involves, which would cause blurring and loss of such fine detail anyway. You can do this for other screen sizes. On a 60" TV, 4K is still not quite in the range of (normal) human visual acuity at 6 feet away. It's close (0.011 degrees), but back off to 8 feet and it drops to 0.0084, or about half of the necessary angle. Which means that on a 60" TV, if you're watching it 6" away you can perhaps just find it a little sharper watching 4K rather than 1080. At 8 feet away, there's literally zero difference. You might, as was pointed out, perceive it to be clearer but that's more likely a function of cameras and the TVs having things like better colour depth and filmed at faster frame rates than it is the increase in resolution. This is also why this doesn't apply to computer monitors. You sit closer to a monitor than a TV, and the images are more likely to be static at least part of the time which allows you to actually detect the higher resolution.

Beyond 4k is useless for how most consumers use standard TVs and monitors in their homes. It is not useless as a video format though. It's also a future proofing measure as there are many kinds of displays and such images will likely be able to take advantage of that level of pixel density in the future. It allows for zooming in with increased clarity, which could be useful for future security monitoring technology. On top of that, it's useful for very large screens. As in theater sized, not home sized. Larger screens require greater pixel density for the same level of clarity as a smaller screen. It also matters for HMD devices such as VR headsets. The screen is literally right in front of the user's face, and has lenses that alter and magnify the image so that it appears correctly to the viewer's eyes. A 4k screen still has the "screen door" effect where you can see individual pixels for devices like these. You need to get closer to 8k or beyond to eliminate it. The closer you are to a screen, the more pixel density matters. This would include AR virtual screens that a user might commonly walk right through in the future. Think someone wearing AR glasses in the future, and walking down a sidewalk with virtual ads displayed outside of stores. In addition to that, it will also be useful for virtual screens to have very high pixel density images. Things like VR and AR in the future will make use of higher pixel density in ways that users will likely be able to perceive. Not just because of the user's physical proximity to the screen, but also because of how virtual screens can be manipulated and used in virtual environments. Think of it as the same reason why 4k textures in games can still matter in a game that only displays in 1080p. A player looking at a 1080p screen can perceive the difference because a 4k texture retains more detail as the player gets "closer" to it in the virtual space. The same thing applies to virtual screens. Basically, beyond 4k is useless for standard consumer level home screens, but still matters as a future proofing technology that has some limited uses today, but will be increasingly important in future technology.

[@SanceShaji]

Thank you for your valuable information about this. You are absolutely right 👍

[@p3rrypm]

That’s largely a BS claim as there are no real consumer grade VR headsets running 4K screens, and the distance to the screen for 4K is literally right on the edge where the pixel detail is blurred together and indistinguishable. At most you would need 5K to make that disappear completely. For monitors, it will make sense for content creators that want to be able to edit many of their images in what is close to a 1:1 ratio. As for future proofing, do you honestly see a day when the average consumer has a TV larger than 160 inches? I do not and I don’t see a time when internet speeds to the home will average the speeds required to meet a quality stream in the next 5 or 6 years. So you’ll likely be buying a much cheaper 8K TV by the time everything else catches up, and even then you would have to be watching that TV at a distance of less than 5 feet to see a huge improvement on a 60” TV screen.

[@contrabardus]

@@p3rrypm Incorrect, as that's mostly a straw man as it doesn't accurately reflect what I said.

There are several consumer grade VR HMDs. That's literally what Oculus, WMR, and Vive are. There are also higher end VR HMDs that aren't really for consumers, such as Pimax and a few others. Some 4K HMDs having very little screen door is a result of a lack of sharpening. The image is literally softened and blurred slightly to reduce screen door. The holy grail is to get to that point without needing to soften the image so that fine detail will be retained. 5k is not enough t o accomplish that. I've kept up with modern VR development since the Oculus DK1, and have seen several professional statements to the effect of 8k is the goal for screens that can provide a decent fov without screen door. 8k VR screens exist now in the form of Pimax HMDs, and due to the wide fov of the display screen door is still visible even at that resolution. Basically, the more you stretch the image, the higher the resolution needed to eliminate screen door. It would also be useful for 180 or 360 degree video files for the same reason, because the image is stretched across a larger area, which lessens the image quality output significantly despite the resolution being high. Again, 8k 360 video files exists, and even when viewed through a high end HMD, the image quality is not as good as even 1080p on a standard screen. It's not just a limitation of the hardware, but of the format itself. That's not even getting into things like AR or retinal displays, both of which are existing technologies today. They aren't available on the consumer market and probably won't be for a while, but they do already exist as prototypes. There's also the 4k texture factor I mentioned. 4k textures are useful even in a 3D environment that is only displaying at 1080p. This is because the user can get closer in the virtual space and the texture will retain a higher level of detail. A good example of how this might be useful outside of a video game would be an 8k image or video file in a virtual screen in a 3D environment that the user can move around in. A virtual art gallery would be one example of a non-game use. 8k has a lot of uses for future technologies. It's a good standard of image quality that is relatively useless in standard consumer level displays because no one uses them with their nose touching the screen, but is still a viable format for recording and rendering because various future displays, both virtual and actual hardware, will likely be able to take advantage of the image resolution.

I completely agree with you. Especially on VR devices. in a couple dozen years, we're gonna need 64k on those bad boys.

[@augustinejovian7600]

So, anything higher than 4K resolution is only good if the frame size (screen display/aspect ratio) is bigger to actually serve the purpose of those high packed number of pixels and that is where lower resolutions like 1080p and 720p don't match up the quality standards?

[@spydergs07]

Good explanation. This is why I like my 85" 4K TV's. You can tell a difference between 1080 and 4K on 85" screens. But my gaming monitors are only 1440 on 27" monitors.

I was waiting for the “Science” part of this. Such a loose term these days...

[@BerkeBoz]

Science: chances are you will not be able to tell the difference in quality and sharpness detail, reason is being there is millions and millions are packed in here. Wow so impressive...

[@dragoonsunite]

@@BerkeBoz Not really science. You kind of just made his point. I worked at the UW eye lab in undergrad for a year. During that time we actually tested these sorts of side by side comparisons. We color tuned the monitors to 99% accuracy using the Adobe Color Space, set their brightness to be identical, and ensured that the pixel gaps for each monitor were as close to identical as possible (To prevent the screen door effect). At typical viewing distances we found people with 20/20 vision could quickly discern the difference between 1080p and 4k with greater than 80% accuracy. Now if your vision has deteriorated, you'll have problems. If your viewing distance is greater than average, you'll have problems, and probably most relevant, if you just don't care about image sharpness, and aren't looking for the differences, you may not notice them. Interestingly, while people sometimes don't notice increased pixel density, they are very sensitive to decreased pixel density. So someone who has been viewing 4k images for months, and didn't think the difference was large before, now suddenly subjected to 1080p video, will notice a stark decline in sharpness, this is double blind mind you. Realistically the sweet spot for most human vision tends to be at something between 1080p and 4k. Maximum visual acuity is around 35 arc seconds, with 20/20 vision falling between 35 arc seconds and 1 arc minute. That said, if the pixels of a device could occupy our entire field of view, the resolution required to ensure no artifacts and maximum use of our visual acuity is a little above 20k (200 degree field of view divided by 35 arc seconds is 20,571.43 pixels). Realistically, that's not how the human eye works. Only the fovea is high resolution, so if a TV were to actually simulate human vision, it wouldn't have the same resolution across the entire panel, we would only stare at the center of the screen, which would be 35 arc seconds resolution at whatever distance we were sitting, and the resolution would sharply drop off as you traveled to the peripheries of the screen. For the purpose of VR this is useful to know for foveated rendering, but the resolution of the entire screen must still be at maximum fovea resolution since the eye rotates independently of the head. In addition, a lot of our visual system is neurologically mitigated. This means for complex images that aren't faces we have an effectively lower resolution of viewing for most people because of how your brain processes images. For faces your brain creates a truer to life representation requiring higher fidelity, and for abstract single objects the resolution is maximized. A single pixel white line slowly rotates on a 4k screen will show obvious visual artifacts called aliasing, because our brain and visual system is capable of picking out the pixels and obvious artifacts of such a simple figure. Artifacts will in fact continue to be visible for people all the way up until 16k for people with "better than 20/20" vision, meaning the best vision available. For people exactly at the threshold of 20/20 vision 10k may be enough for them to cease to see artifacts, since their resolving capability is at an arc minute. For most visual patterns though, the brain simplifies, tending to cluster together objects to make colors, patterns, shapes, and identifiable figures. Representations are created that aren't really there for peripheries. You think you see in color and in detail things out of your peripheral vision, but you really don't, it's just your brain filling in the gaps for you. In any case... "generally" for most people, particularly as you get older and your vision declines, and if you have your TV sitting 10' away across a living room, 1080p is more than adequate... If you have good vision and you sit within 5' feet of your TV, this video becomes relatively inaccurate. If you are playing in VR and the screen is an inch from your eye, this video is totally irrelevant because it did in fact not explore any of the science of visual acuity at all, it just made general statements about resolution that have nothing to do with eyesight.

Cinema vs Consumer (around 4min...) 256 memory pixels are used for layering or interlace by company insertion? Deepfakes are added in it? What is the memory used for? 4096-256 = Consumer value. So is this the cybersecurity to make sure what is viewed does not have insertion through these memory method from wavespectrum signal?

[@GhostStealth590]

As many point out and can’t make the distinction, FOOTAGE in 8k is quite amazing, however displays in 8k are useless. Honestly shooting in 8k to 16k and above gives tremendous advantages in the editing room when needing to do serious cropping and zooming (computer intensive granted). Just distinguish the 2 differences between footage and display.
