/titleI'm getting a new screen for christmas as I need one badly. My current one is almost square.
Get at least a 24" screen. Make sure it's full HD.Here is the one I have; this one appears to be a more updated model though.http://www.amazon.com/Asus-VE248Q-24-Inch-LED-Monitor/dp/B005BZNDHQ/ref=sr_1_3?s=pc&ie=UTF8&qid=1349298142&sr=1-3&keywords=asus+HD+screen
1920x1080 is the max people usually get because that's the resolution of a full HD tv, and most high quality videos are HD.
or they get a 27" with a 2560x1440 :)
