    Science or not I am 70 and wear glasses both for distance and reading. Even with these older eyes I an enjoying the tremendous clarity of a 65 inch 4k screen I just replaced my 55 inch 1080p screen with. I have also demoed 8k and it is clearer yet even to me. If my old eyes can pick this up you younger people should see great improvements in picture quality at every level. I plan on getting an 8k soon.

    People seem to not understand its not about how your putting it in regards to cant see the pixels, 8K and higher is all about depth. Seeing 8K back in 2012/2013 that was the first thing I could tell was depth and when talking with people from NHK, Sharp and others when saying depth they say "Exactly". Not long ago talking with NHK they say 32K is the stoping point, like the olympics are going to be shot in 8K and possibly shot in 16k if camera is reddy, and broadcasted in 8K in Japan. Any way with seeing it my self many times over the years I definitely can see a difference regardless of size in the TV range at least and my eye sight is not perfect.

    The subject is already complicated enough, why do you speak soooo damn fast (i mean imagine using that speed in front of an audience, everyone would be lost) and switch between metric and imperial metric systems ? I appreciate you saying the two but sometimes you only used the imperial system like for the size of the TV. Centimeters are a very useful thing, maybe try using these too ?

    Anybody else notice the irony of his fine patterned shirt moire patterning to all heck at 1080? Is 8K pointless right now? Sure… But will it have use in normal-person life? Eventually, for certain. Raw resolution isn’t simply about how well one can discern individual pixels in a moving image. That’s hard even at 1080. Jaggies, stairstep effect, and moire patterns are all image quality issues that real people see every single day. I can tell instantaneously between 4K and 1440P in Forza Horizon 4 running on a console simply because the bumper on your car shows a dramatic stairstep effect across that mild improvement. To say that the resolution will have no benefit to mainstream users outside of hyper-large-format and uberrich people who don’t know any better is incredibly shortsighted, and frankly disappointing coming out of what I assume is a dungeon filled with video editors chained to desks. People made the same arguments about 1080, and 4K. They were wrong. It’s disappointing that the Scishow doesn’t talk about any other image quality performance aspects of higher resolution other than being able to discern two individual pixels. The likelihood of you being able to discern the difference between two individual pixels has much more to do with the type of content being displayed than the resolution in most cases.

    Those that say 1080p is good and 4k or 8k is a waste. You are so wrong. There's a big difference in the quality it's noticeable. And 4k is very affordable now I bought a 55 inch 4k for 400 with Dolby vision. It's worth it, but if you don't care for the best, stick with whatever you got. I'll upgrade to 8k once it's more affordable

    Movies are hardly ever true 4K let alone 8K. Most movies are mastered in 2K, which is just regular HD, and then upscaled from there. It's the only way to render all that photo realistic CGI within acceptable timespans. 4K would take 4 times as long. And imagine 8K movies taking 16 times as long to render as current blockbusters. Just get 4K TV or even just a full HD (2K) TV with HDR and enjoy.

    The point of high resolution isn't for humans to discern the increase. Its to provide a detailed enough image that it would trick the brain into thinking your looking at a window instead of a tv.

    I HAVE A QUESTION! That's right, I yelled. Is there a chance that the 60" 8K TV will make your regular HD shows look worse? For example, viewing TR-center at 240p on a 21" HD widescreen monitor looks terrible, but that same video on my 14" 480p full-screen looks reasonable. Less image stretch looks better, yes?

They clsimed they could hear and discern down to 0.005 percent Total Harmonic Distortion. Science later proved that most humans can only discern 2 percent. This is the same thing. People are going to claim they can see the difference.

    I feel like there's something wrong about the logic used to show people "can't see" the difference. The main problem is that it's conflating "the detail the human eye can see at any given time" with "the experience of viewing image/video." This is an important distinction, because the experience of actually viewing things consists of your eyes constantly darting around and taking in a bunch of visual information, which is then processed by your brain. 4k content displayed by a 4k display contains more actual detail, so it's entirely possible (if not outright likely) that the net result from someone viewing it will be different, because even if they can't see every detail at any given instant, that doesn't mean they aren't picking it up in the process of viewing. The only real way to judge this would be a double-blind test. The only one I could find was from 2013* and gave a very clear "almost everyone can tell the difference" result (97% correctly identified the 4k), though I would like to see the result of other tests if they exist (Google isn't yielding anything else). Obviously, all of this is contingent on the source video actually being recorded in 4k. If it isn't (which it isn't for most television) the conclusion of this video is obviously correct. * www.hdtvtest.co.uk/news/4k-resolution-201312153517.htm

    This video is misleading at best. Have you yourself seen an actual 8K content on a 8K TV...? We do have a 70” 8K TV and access to properly produced 8K content (here in Japan NHK is broadcasting in 8K from 10AM until 10PM since last year in preparation for the official public launch of 8K during 2020 Olympics) and pretty much everyone who has seen it thus far from our comfortable 2.5m viewing distance can immediately tell the difference from 4K (let alone HD). Ironically (and accidentally) you got close to the key point - that from a certain distance two points will merge and look like one. But we are not robots and our eyes don’t have sensors. The photo receptors in our eyes are not organized in neat rows and columns (like in a camera sensor). However the goal is similar - not being able to “sense” any particular resolution / artificial pattern. To put it in a plain language - with 8K the pixel grid is all but gone. Even the most sensitive eyes can simply focus on tiniest details and not be reacting to any artificial pixel pattern. This is why the most common reaction from people is comparing it to “looking through a window”. So please stop “over-sciencing” everything - especially things you don’t have any personal experience with...

    One thing you didn't touch on is defective pixels. My 1080 display has a few dead pixels (the manufactures seem to make failed pixels just black out so they aren't typically all that noticeable) In a 4K or 8K display, a dead pixel would be very difficult to even discern. Is failure a reason to buy a higher res display? I'd say YES!

    TVs are on the cusp of entering a hifi style arms race, where the product is essentially perfected, so manufacturers have to invent reasons to convince people to carry on parting with their money.

    I have 20/30 vision, and pack my glasses to see movies in theaters. 20/30 doesn't need them to drive or really suffer any quality loss at home. It's only those massive quality levels on similarly massive screens that suffer. tldr: Even imperfect vision gets everything out of a 1080-p home screen.

    For any of these edge of perception issues (resolution, frame rate, color space, etc), you'd optimally want to *exceed* the human limit - and by a reasonable margin - not just match it. Something like a 16kTV at 2kHz with 16-bit-per-channel floating point color (maybe with more than 3 color channels) is probably the point where further improvements are conclusively pointless. The 4k to 8k upgrade is probably a bad deal for TVs at any significant cost premium - but it's still well within the realm of actually doing something.
