What is coming after 1080p?

And the optimal viewing distance for any screen is being positioned between one and a half times (1.5 x), to two and a half times (2.5 x) whatever the screen size is away.
So if you have a 50" screen, position your sofa/couch/lounge within 75" and 125" away.

yea i'm pretty sure any upscaling actually degrades the picture slightly. if the picture pixels don't divide equally you have to average/sample something somewhere.

Yeah it does because it has to use the same quality footage and stretch it over more pixels than it originally had. If that guy can't tell the difference between dvd (576p) and Blu-ray (1080p) , then he needs is eyes checked. Even the difference between 576p and 720p HD is noticeable.

I'm personally not happy at all with the current crop of "4K" TVs. Here is my biggest issue, 4K had an established digital film resolution of 4096×2160. Almost all digital movie theaters used projectors with this resolution, which meant that the actual movie itself was cut and edited with this resolution in mind. So what resolution do the "4K" TVs use? Yeah you guessed it, not 4092x2160, but 3840×2160, which means that all the video shot and edited for 4092x2160 has to be resized, or cropped to fit on that screen. And since 3840 is by no way/shape/form a whole multiple or fraction of 4092, it means we get all kinds of image distortion as the algorithms now have to decide what color to make each and every pixel since there is no way to map any pixel from the 4092x2160 frame into the 3840x2160 frame, and they now have to decide on if the new pixel in the 3840 image will be 95% this color and 5% this other color....

All of which is stupid and a non-issue had they simply used the 4K standard that already existed which also already had hundreds of thousands of hours of material ready to view on this "new" TV format.

Why does this even matter, it's obvious that the HD signals (be it 4KTV or Bluray) will be encoded as 3840h x 2160v. And it doesn't matter how that is achieved, the studios/broadcasters will use either cropping or advanced scaling algorithms that will produce indistinguishable results. This isn't something you need to concern yourself with, after all a lot of digital movies today are shot in 4K and resized to 1920h x 1080v, which also isn't a factor of 4096h... so don't worry about it.
