The title says it all. It needs to be 27" at least (more is better) full HD 1080p at least (if there's a 1440p in my budget please tell) and have a response time under 10ms
I've been looking at getting one and noticed that some of them have the glossy screen and some have the matte so make sure you get the one that you want. I prefer matte and was under the impression that they were all matte. Evidently, that's not the case. Either way, I've heard nothing but great things about the QNIX. Great suggestion!
