1920x1200 is probably a bit much for your card bandwidth-wise. Do lower resolutions work ok? (1680x1050 or 1024x768) You might try reducing your color depth to 16 bits. The following options may also help: Option "DefaultTMDSPLL" "TRUE" Option "DisplayPriority" "HIGH" If that doesn't help, try a modeline with a reduced refresh rate (50 hz rather than 60): Modeline "1920x1200_50.00_rb" 127.75 1920 1968 2000 2080 1200 1203 1209 1229 +HSync -Vsync Alex -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
