I currently have a 19inch CRT but i need to get an LCD one. I wanted to get a 19 inch LCD but when i went to my friends house his 17 inch LCD looked just as big as my 19 inch CRT, so mabey 17inch is enough.
I'm a lot on the computer so i need a screen that won't give me headaches

and that plays games fine ( low response time, high resolution).
Also is getting a widescreen LCD a bad idea for playing games?
Thanx
