TV screen size to notice 4k resolution?

If without HDR it's 4:4:4

With HDR it's 4:2:0 white brighter.

That's interesting. 444 4k material is very rare, i am interested to see how H.265 holds up because that's a fair bit of compression going on.

My sentiments exactly.

I see the difference on my tablet.

UHD picture quality on my Sony 55X8509C is fantastic and the detail is a massive step up from 1080p content. A bigger screen might benefit even more but with 55" you can totally see a big difference.

Even a smaller TV will still benefit to some degree from the detail that UHD offers (or they wouldn't make smaller UHD TV's) but a bigger screen will look better.

Here's my take on the value of 3840x2160p resolution advantage over 1920x1080p viewing distance limits.

If you have 20/20 vision with or without corrective lenses your eyes have the acuity to see the resolution advantage of 4K up to 2x the height of the screen and you can see a more significant resolution difference at 1.5 x the screen height. At slighly further viewing distances you can make out a slight overall image sharpness advantage, but it's very minimal and goes away quickly as you move beyond 2x the screen height.

HDR, WCG and the 1096 illumination steps that are native to 10-bit panels are very easy and enjoyable to see at any distance so bring on 4K HDR!
