Yes, 720x480 works without the -r parameter. > Looking at your EDID, you have: > > Established timings supported: > 720x400@70Hz 9:5 HorFreq: 31469 Hz Clock: 28.320 MHz > 640x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 25.175 MHz > 640x480@75Hz 4:3 HorFreq: 37500 Hz Clock: 31.500 MHz > 800x600@60Hz 4:3 HorFreq: 37900 Hz Clock: 40.000 MHz > 800x600@75Hz 4:3 HorFreq: 46900 Hz Clock: 49.500 MHz > 1024x768@60Hz 4:3 HorFreq: 48400 Hz Clock: 65.000 MHz > 1024x768@75Hz 4:3 HorFreq: 60000 Hz Clock: 78.750 MHz > 1280x1024@75Hz 5:4 HorFreq: 80000 Hz Clock: 135.000 MHz > Standard timings supported: > 1920x1080@60Hz 16:9 > 1600x1200@60Hz 4:3 HorFreq: 75000 Hz Clock: 162.000 MHz > 1280x1024@60Hz 5:4 HorFreq: 64000 Hz Clock: 108.000 MHz > 1280x800@60Hz 16:10 > 1152x864@75Hz 4:3 HorFreq: 67500 Hz Clock: 108.000 MHz > > CTA extension block > Extension version: 3 > 25 bytes of CTA data > Video data block > ... > VIC 3 720x480@60Hz 16:9 HorFreq: 31469 Hz Clock: 27.000 MHz > VIC 2 720x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 27.000 MHz > VIC 1 640x480@60Hz 4:3 HorFreq: 31469 Hz Clock: 25.175 MHz Okay, if I read all that right the EDID supports 640x480 at 60 and 75hz. The monitor acts strangely at 60hz but is okay at 75hz. Is this something I should configure or can nouveau figure out the best mode? -- Dan Espen _______________________________________________ Nouveau mailing list Nouveau@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/nouveau
