Not all graphic cards support 3 monitors. If you want seriously cheap and pretty good monitor, you can go with something like this one Or even better, two of them Sceptre TVs have, historically, provided a dedicated monitor mode on them, that's why I'm stuck on recommending them. For purists, the problem with using something like the TV I cited above vs a dedicated monitor involves slight (50ms or so) lag times and some (again, slight) text quality problems. AFAIR, Sceptres are pretty good about lag times - I think I saw some mentions of 25ms lag times and, seriously, unless you're a dedicated gamer, it doesn't matter. My brother is a purist and looked at my Sceptre 32" monitors and scoffed. When he tried to point out the problems with them, I honestly tried to discern them and failed.
