I personally use a BenQ monitor on my PC (Model no E2200HD).
It's great for PC gaming, and I have also plugged my PS3 into it to test stuff out. Games look great and run great on the monitor. It has a HDMI connection, which is what you want. My only criticism is the built in speakers kinda suck, but I believe there is a headphone jack on the monitor. I just haven't needed to use it so never bothered to look.
