People are still waiting for cheap real 4k projectors on 3 x 4k panels... a whole 7 years have passed since 2016...But where are they?
Meanwhile, there was simply nothing to watch - Hollywood died, just like European cinema. Games? But they just need an honest 4k@144Hz (real ones with a real minimum input lag and a response of no more than 5-6ms on G2G/B2W) in 4k, but where are they? There is none of them...
