My projector is 8K branded (technically it's a 4K panel, but it uses pixel-shifting to do "8K") but don't think I've found a single piece of 8K content I've wanted to watch on it (admittedly, there would be some faffing involved as unless I pay for the 8K software upgrade for my amp then I'd also need to mess around with connecting devices directly). I really wonder how much better it would look than 4K even on a 110" screen. I guess maybe in a dedicated room with a 200" screen it might give a decent upgrade, but unless I buy a new house then that isn't happening!
