A:Answer "PCGamer," I own this set and am using it as a monitor. There is no noticeable input or visual lag while gaming, but if you're worried about unnoticeable lag, spend $1,000 for a "1ms" 32" panel. :) (It's your money.) Your comment regarding seating distance is logically reversed; you want a bigger panel with 4K because you won't be able to resolve the additional resolution provided by only a 28 or 32" screen unless your nose is literally pressed against it. The ideal seating distance for a 40" 4K panel (makes no difference if a "monitor" or a television) is 2'11", which is right around typical for the average desk-seated PC user. Even at 40", it's tempting to enable DPI scaling; at 28 or 32", it would be a necessity (unless, again, your nose is pressed against the screen while using it). As you clearly haven't used a modern "television" as a monitor, please don't parrot the nonsense of others who also haven't.
