I recently re-installed all the system software on my hard drive. Now when I run my OpenGL program I get a "OUT OF SCAN RANGE" error on my display monitor. My program switches the display to 640x480x16 full screen mode. I have a Sony Trinitron MultiScan 200ES. I had this problem before but I totally forgot how to fix it. I don''t even have the Sony monitor manual anymore. Can someone help me?

This problem can be caused by two things (at least) that come to mind. Either you are running a refresh rate that is not supported by your monitor/card. Or you''re running a resolution that is not supported by the monitor/card. What I reccoment first, is going into advanced display settings opengl sub-system settings and changing the value under v-sync. There is a good chance this will solve the problem. Seeing as it''s with opengl and you ARE using a supported resolution, that is most likely it. Good luck with it.
