I've been strongly considering an M-series (probably 55") but I'm also interested in the P-series. But since I expect to mostly use it with 1080P content I'm wondering how the 4K screen deals with it.
My understanding is that in general 4K displays will do some upscaling/upsampling, interpolating the 1080P pixels. However, is there ever an option to do straight nearest-neighbor scaling, such that one 1080P pixel becomes four (2x2) pixels on the display? Or for a 720P image, nine (3x3) pixels.
The reason that I ask is that in general, anything besides pixel-perfect nearest neighbor scaling results in blurring, which I try to avoid in games with pixel art. I would most likely want to connect a computer outputting 1080P (at 120Hz), so I would want to keep the image as sharp as possible. Basically I would prefer the "Blocking" outcome (left image) in this picture: https://s3.amazonaws.com/red_3/uploa...-artifacts.png
I realize the P-series isn't out yet so it's hard to say for sure, but my impression is that 4K TVs never allow this "blocky" scaling of 1080P content and always produce a blurrier image than a 1080P screen of the same size. However I also realize that the pixel density might be so high that the effect is hardly even noticeable.
I know this is a pretty obscure request, but does anyone have any thoughts or experience with this issue?
Along the same lines, I would expect 720P content to look better on a 4K display than on a 1080P display, due to the 3x integer scaling. Does anyone know if that's actually true?
