from what i've seen the Asus MK241H is the best gaming monitor in the size range imo. the 3000:1 contrast ratio crazy awesome crystal clear image. 2mhttp://www.techist.com/forums/images/icons/icon10.gif
Talkings time virtually no ghosting or tracing. comes with built in webcam, mic and speakers not a huge deal lol but a decent perk.
Still full hd and same ratio just as the others.
only con is that the monitors base isn't really that adjustable no pivoting, no height, adjustment and no swivel just tilts up and down.
on the bright side asus makes quality product
