I have already tried modelines and VertRefresh ranges (43-75 and 60-75). I'll try ModeValidation and AllowNon60HzDFPModes today, also.
Here's the xrandr output: SZ: Pixels Physical Refresh *0 1280 x 1024 ( 382mm x 302mm ) *50 51 1 1280 x 960 ( 382mm x 283mm ) 52 2 1280 x 800 ( 382mm x 236mm ) 53 3 1280 x 768 ( 382mm x 226mm ) 54 4 1152 x 864 ( 344mm x 255mm ) 55 5 1024 x 768 ( 305mm x 226mm ) 56 57 58 6 960 x 600 ( 286mm x 177mm ) 59 7 840 x 525 ( 251mm x 155mm ) 60 8 832 x 624 ( 248mm x 184mm ) 61 9 800 x 600 ( 239mm x 177mm ) 62 63 64 65 66 67 10 800 x 512 ( 239mm x 151mm ) 68 11 720 x 450 ( 215mm x 132mm ) 69 12 640 x 512 ( 191mm x 151mm ) 70 71 13 640 x 480 ( 191mm x 141mm ) 72 73 74 75 14 640 x 400 ( 191mm x 118mm ) 76 15 640 x 384 ( 191mm x 113mm ) 77 16 576 x 432 ( 172mm x 127mm ) 78 17 512 x 384 ( 152mm x 113mm ) 79 80 81 18 416 x 312 ( 124mm x 92mm ) 82 19 400 x 300 ( 119mm x 88mm ) 83 84 85 86 20 320 x 240 ( 95mm x 70mm ) 87 88 89 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none The current mode is marked with an *.
