Looks like whatever game you are using is forceing a refresh rate beyond what your monitor can handle for that particular resolution -or- your monitor can't display that resolution. First of all install detonator 45.23 drivers. Then change the resolution that game runs on to something more standard like 1280x1024 and see if the problem goes away. If it does then you are just back to the problem of having 60hz refresh rate on all direct 3d and opengl games. Now download one of the many utilities to fix the refresh rate problem. I prefer Refresh Force:

This will probe your monitor and video card and set the refresh rate as high as possible for all possible resolutions...now keep in mind that it's not perfect. If run a particular game and you keep getting the "out of scan range" error, run refresh force again and manually lower the refesh rate the whatever resultion you are having problems with.
