Tim-in-CA said:I have played HL2 and Prey and have had no issue with the monitor. I pumped all the settings to their max on HL2 and still did not see any of the video issues. You may see some tearing, but that's because Wait for VSync is disabled by default ... if you enable that, you will not see this (this is typical of other monitors I have had). Also, the going bright and dark and bright is an effect of HDR lighting effects in HL2. It can get annoying, but once again, it is the same on others I have seen. I think that you will be very happy with the display ... good luck ....
I'm curious, have you gone to the link I left earlier, to see if you had any flickering? Its the same flickering I experienced playing half Life. If you dont see it there, maybe its a defect on some monitors. In case you havent, here is the link.

When You get there, slowly move the vertical window slider up and down. the blue textured background on either side should flicker like crazy, that is, if in fact, all gateway 24 inch monitors do it. If it doesnt, maybe there is a bad run of this monitor.
