well. i have money to spend and previously i was thinking of changing my dual 21.5inch setup to a larger dual 27inch setup.

so then i realized, if i were to get both 1080p monitors that would Not give me more screen real estate, so whats the point other than having a larger display for movies/games if i cant fit more stuff onto my desktop.
Im also concerned if since its larger, can we really feel the difference in the clarity seeing as how 21 inch and 27 inch have the same amount of pixels would it make the 27inch blurry-er/ ugly

then i thought about getting a 1440p display. but graphic card only 750ti, tapi i also dont play alot of hardcore games on PC since i use my ps4 for that. so now im slightly torn on what to get
but generally i was looking into the dell S2715H.

any thoughts?
