What the hell, the ideal size for 4k resolution scaled from a 30" 2560x1600 is about 40".
What is with these small 8k/4k monitors? Useless. I just buy TVs with HDMI 2.0. 50" 4k tvs are, what, $400 these days?
I get more pixels can be nice, and 8k is probably where that comes into play, but if I have 8,192 lines of resolution, I want some screen real estate too.
