Sure, this graphics card is pretty old and not very powerful. However: * I used it to drive the VGA output in 1920x1440x75Hz for 7 years with my 21" CRT. * About 6 months ago I switched to an LCD screen and used it to drive the DVI output at 1920x1200x60Hz without trouble. * It's only last wednesday when I upgraded that the DVI output stopped working at all. * I have since downgraded the driver to and I'm using the DVI output in 1920x1200x60Hz (as confirmed by both xrandr 1.1 and my LCD screen). So it's not a hardware problem. > Do lower resolutions work ok? (1680x1050 or 1024x768) You might try > reducing your color depth to 16 bits. I thought about an issue with the single-link DVI bandwidth limit too. So I tried 1600x1200x60Hz and 1024x768x60Hz and neither worked. I did not try 16 bits mode. > 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 I will try this tonight. Do these correspond to driver settings that changed between 6.6.3 and 6.8.0? -- Francois Gouget <[EMAIL PROTECTED]> http://fgouget.free.fr/ Avoid the Gates of Hell - use Linux. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
