I have a limit of around $650, but obviously a cheaper monitor is preferrable. Right now I am looking at these two.
SAMSUNG T27B750ND LG 29EA93-P
I can't decide whether a 21:9 screen is a good idea, or if I should get two 23" or one 27". Please feel free to suggest monitors and layouts. Oh also I'm trying to get monitors that both function great and look great.
However, that is way to cheap. So for you son, a monitor which can decimate things at 2560 x 1440 is relevant: http://pcpartpicker.com/part/asus-monitor-pb278q
Featuring all the things from the last monitor, except with more screen, more resolution, more price, more BALLER.
