GeraltOfRivia_PL: Did you start feeling shame about not being on 8k?
You seriously need to stop reading those certain other e-peen addiction based forums then creating "guilt" based threads here based on what the more snobbish fringe members of those other forums sh*t-post over there. Reality = 80% of the market are on 1080p or lower, another 10% on 1440p, 4k is barely 2% and 8k virtually non-existent.
Pro-tip - Unless you own a giant screen (which are often rubbish for ergonomics when sitting close to, eg, increased head / neck movements, the urge to constantly lean back to see the top of the screen and increased fatigue during longer sessions), or are into pro photo editing, 4k isn't even desirable on normal sub 32" size monitors due to the way UI / HUD's don't scale well in many older games.
