I have a Samsung 172X and a Sony SDM 17. Neither of them have any problems during gaming. I would recommend the 172X, it goes for very cheap at newegg.com considering it has DVI input. I've noticed on 19 inch LCDs that use analog input, ghosting is more apparent. The monitor in particular was a low end Samsung 910 Model. Other things to look at is how the monitor will be positioned in your setup. While the Horizontal viewing angle is generally good on most LCDs, the vertical veiwing angle can make the monitor seem not as bright. Ensuring the monitor you get will be even with your line of sight is important. Another reason Why i like the 172X - its wall mountable out of the box, so you can just have it in front of you, exactly where you need it. Good luck with your choice!
