I just got a Samsung SyncMaster 997DF, and I was having some problems with the screen flickering. I figured out that it only happened when I was running 1600*1200 @ 70hz. I also figured out that even though windows hides the options above 70hz, this monitor can still handle 75hz @ 1600*1200. Anyway, I set it to 75hz, and the flickering has stopped in windows completly, but now games will only run at 70hz, and wont stay set on 75hz. So when I enter a game, the refresh rate changes. What do I have to do to keep the refresh rate the same for everything?
