It's one of the main reasons why 4k is a big no no for me at the moment.
i get the impression from articles online etc that to get the full benifet of 4k 55,60,65 inch screens just are not big enough.which kind of makes you think what is the point of 8k or 16k .the Japanese are skipping 4k altogether and going straight to 8k for the Olympics.
if 75-85inch screens are recommended for 4k then what chance do any of us have in experiencing the full benifet of 8k etc in fact as the resolution increases it's our eyes that will eventually let us down because they won't be good enough to see all the detail.
for all the people that spend thousands on a new 55-65 inch 4k tv I'd love to see a standoff with a flagship calibrated 1080p tv v a calibrated 4k tv both playing skyfall in Blu ray and 4k version if and when available I doubt there would be much difference .
how many people even if they could afford it would want a 70-80screen in their home it's fine if you have a dedicated home cinema room etc but for your average uk living room it would be a big black monstrosity sitting in the middle of the room.
