The eye is analog. Randomly analog at that. Is there some wiggle room thanks to variances in how people see? Yes, of course. Here's an awesome chart:. Let's skip ahead a step. Getting bogged down in the specifics misses the big picture. You're just saying that smaller 4K TVs are viable. How much smaller? Well, not 50 inches. Probably not 60 inches, either. These are the sizes people are buying. Most people are buying even smaller TVs.
Which leads to Never ever. Like I said earlier, I have a inch screen. I've also reviewed an inch Sharp LCD. And let me tell you, it dominates the room. It's massive. There is a significant difference between a screen effectively, the wall , and a Device of Unusual Size. Enthusiasts might be OK with this thing in their room, but most people won't. Ask your spouse. Ask your spouse's friends. Screen sizes have been inching upward, but not linearly with price. More specifically, the prices of big-big screens have fallen much faster than their sales have increased.
I don't know what the upper limit is for what the average consumer decides is "too big" for their room, but I'm positive there is an upper limit, and this limit is far smaller than screens that need 4K. I should clarify what I mean by "TV. When OLED becomes something you can paint on your wall, or so paper-thin it hangs like a poster, then absolutely people will get bigger screens presuming they're cheap.
However, this is years decades? This future awesomeness is different than TVs of today. Will we still call them "TVs"? Yeah, probably, but their presence in the room will be radically different, hopefully because these future wafer-thin "TVs" won't have a presence in the room.
They'll be part of the wall. There were good reasons for this scan lines. Modern TVs offer significantly better resolution, so people can sit closer. Most people still sit the same distance from their TVs as they did before. Could people sit closer? A lot closer, actually.
This ties in exactly with point No. Sitting closer would be like getting a bigger screen, as it takes up more of your field of view. Just as people aren't getting as big a TV as they could, people aren't sitting closer, either. So they can sit closer now, but don't. Why would anyone assume that because of UHD, people would suddenly sit closer. It doesn't make any sense. And just like with No. Some of you might want to sit 5. And speaking of viewing distance, this is precisely why comparisons to the Retina Display iPad are specious.
The viewing distance is rather different between a TV and a tablet. Raymond M. Soneira says, your TV is already a Retina Display. Why 4K? Ah, now this is an interesting question. It's clear many seem to think TV manufacturers are some sort of altruistic entities that only do new things if there's a benefit to the consumer. How adorable, but no.
Ultra HD isn't the "new technology" it appears. Modern TVs are made from huge sheets of "motherglass. It's easier read: cheaper to make a big piece and cut it into smaller TVs. Originally this was in case there was a problem with part of the glass, the rest could still be sold as TVs. When you read about "yields" as part of TV manufacturing, this is largely what they're talking about.
But manufacturing has gotten really good, so most of these pieces of motherglass are fully used. Instead of slicing up one piece of motherglass into four inch p LCDs, what if you just kept the whole thing as one piece? What would you have? You'd have an inch TV.
Hey, wait. You see, TV companies are pushing 4K because they can. It's easy, or at least easier than improving the more important aspects of picture quality like contrast ratio, color accuracy, motion blur, compression artifacts, and so on. Ultra HD is an easy sell.
It's a number, greater than another number; therefore it's "better. This is just like megapixels on a camera. An megapixel camera does not necessarily take better pictures than a megapixel camera. I guarantee my SLR takes better pictures than a "higher-resolution" point-and-shoot. Numbers are easy to understand, and for nonenthusiasts, distilling a TV down to a single number is desirable. This was rampant in the early days of p.
I actually heard people say "I don't know what p is, but I know I'm supposed to want it. It's also an easy demo I'm a 4K TV skeptic from a real-world image quality perspective, but I could see them selling -- they have a wow factor from up close ces. Sexy bald head aside, when people talk about seeing 4K, they are way closer than they would normally be. Up closer, yeah, 4K looks amazing. This is, of course, how they'll sell in stores.
People will walk right up to the screen and go "Wow! It looks neat, it has a number greater than another point No. The lack of content is not the problem So much coverage has focused on the lack of 4K content. This is not the issue.
It was years before HDTVs had meaningful amounts of content. Presuming points No. Again, this is presuming you're close enough to see it. Upconverted content is not the same as real 4K content , but it's a step. Passive 3D is far more pleasing to watch than active 3D , but you lose half the vertical resolution i. This is still the case with passive 4K TVs, but you can afford to lose it. This also opens up possibilities for viewing two different programs on the same TV.
Using polarized glasses that block the same lines for each eye, two different 3,x1,pixel programs could be enjoyed by different people on the same couch. So the Missus could watch the game while you watch "The Bachelor" presuming you have two cable boxes or an antenna. This is somewhat possible now though this is half-HD resolution and Samsung demoed a prototype version at CES , so this isn't strictly a 4K thing, but it is an interesting use.
There are bigger issues My biggest complaint about Ultra HD is what it doesn't address. Resolution is not the most important aspect of picture quality. Nor, as we've discussed, is it even a problem with current picture quality. How about improving contrast ratio, color, and compression artifacts? These all have a significantly greater effect on picture quality than resolution. I'll add another problem to the list of things 4K doesn't address: motion resolution.

So existing x HDTVs are “retina display” in exactly the same way as the existing Apple retina display products. If the HDTVs had a higher pixel density. The new (inch and inch, 3rd generation) iPad Pro models have an all-new design that features Face ID, the advanced Liquid Retina. Retina displays have little to do with the resolution. · For instance, Vizio has TV's that are 4k 65″, and you can clearly see the pixels. · Retina displays can.
