Realistically I need a high refresh rate (120)and preferably 2k res. If I can't get hold of that for 300-400 dollars then I will look at 1920 x 1080 or 1920 x1200. Also my screen size has to be capped at 23 or 24". Don't have space for anything larger.
Am currently using my HDTV for my comp too but that's a pain when I need to actually work on it.
