I'm shopping for a newer monitor I can use for college and shite. Some things I am looking for is something that could be from 19-22 inches, also something that preferably has a low input delay, like 2ms or less. I'm budgeting around $200 or so, could go higher if there is something out there that's really good, but staying in that range would be ideal.

tl;dr, looking for a 22"/2ms portable monitor for about $200 usd. Any recommendations?
