I like playing on smaller screens. 19" - 22" is my comfort zone. If i had a 27" monitor I would have to sit further away but It would make reaching for the mouse and keyboard uncomfortable. I'm currently looking at 21.5 PLS 1080 monitor just because I don't want something that big in front of my face where I would have to turn my head to see certain parts of the screen. I like everything being in my field of vision with very little eye movement and no head movement. This is why I don't like triple monitor setups. I'm torn because I really want 1440 or even 4k with that new 28" rog monitor asus released for only $700.00 but the way my apartment is set up I'm extremely limited to how I can arrange my gaming area to make a bigger monitor more comfortable to my liking.
