When HDTV was first being developed, it became apparent that there were two differing motivations.

We are familial with the motivations in Europe and the US. But in Asian countries typically rooms are smaller and people sit closer to the screen, so higher resolution means pixels don't look so big and blocky.

NO! it's about angular resolution!, sit close to a small screen or further from a large screen, the result is the same......

I'm not quite sure what you are saying,but I think you have misunderstood.

In Asian countries they often sit so close to the screen (small room size) that individual SD pixels are too visible. HD with the same screen size and same distance has smaller and therefore less visible pixels.

Yes and as soon as you move further away your screen gets bigger. I have a 42" monitor and 27" monitors. Both 4k, both look the same because I sit as close as 0.5m from the 27" ones but will be about 1.5m from the 43" one. The eye has an angle of view, The pixels actually take up an angle of our vision so it is about angular resolution. if we can see 150 degrees across and want a 4k monitor that is 150/4k gives you the angular resolution. That is fixed because we will always change our distance from the monitor based on it's size unless you are like my ex colleague with eye sight problems that had a 32" and put his eyes up to it with enlarged text.

Interested to see where monitor tech goes. I have a 27” 4k and a 27” 5k next to each other and the 4k one looks horrible now. More pixels really does help with text sharpness and eye strain.

I just don't "get" 8K.

I have 4K monitors for my PC.  These are 28" across and I sit two feet away from them so consequentially, I can resolve the added detail.  I think 5-6K would be the maximum resolution before I could no longer resolve the detail.  I have perfect 20-20 uncorrected vision.

A TV screen is typically 8-10 foot away from the user.  You can't even see the benefit of 4K at that distance with a screen up to 65".  It looks better than 1080p but you aren't getting the "full" experience.

For video editing and filmmakers I can see the advantage of doing all the mastering in 8K and producing a 4K output.  And those people will probably benefit from an 8K monitor 50" across two foot away from their eyes.  But for the general public watching the film on their TV?  I just don't see it.

TV manufacturers will push it because it's the next big thing, like 3D, but I expect it will fizzle.
