28 is about as big as you want to get for 4k.
This is what separates TVs from monitors: viewing distance.
The further you sit away from something, the less you'll notice jaggies, textures and the like, which is probably why gaming consoles constantly get away with sub-1080p resolutions.
I'm confused. Reviews of 28' 4k monitors have people saying "screen
size is a bit small for such a high resolution, harder to see some for some users"
and you're saying the exact opposite hmmm. so it would be easier to use a monitor like this
even smaller screen you think?
