- My Tseng Labs ET4000 plus (48KHz,60Hz) monitor like these values:
-
- Virtual 1024 1024
- ViewPort 0 0
- # Modes "1024x768" "800x600" "640x480" "1240x768"
- Modes "1024x768" "800x600" "640x480"
- Clocks 25 28 32 36 40 45 31 38 51 56 65 72 81 90 63 75
- # Staticgray
- # Grayscale
- # Staticcolor

- Chipset "et4000"
- # Displaysize 1024 768
- # Screenno 0

- ModeDB
- # clock horzontal timing vertical timing
- "640x480" 25 640 664 760 800 480 491 493 525 # 31.25KHz x 60 Hz
- "800x600" 36 800 824 896 1024 600 601 603 625 # 35KHz x 56Hz
- "1024x768" 65 1024 1032 1176 1344 768 771 777 806 # 48KHz x 60Hz
- "1240x768" 75 1240 1264 1560 1584 768 771 777 806 # 48KHz x 60Hz

- 1240x768 runs fine, but I prefer a virtual screen with a higher vertical
- resolution. Note that the psysical vertical resolution is limited by
- 48KHz / 60Hz / 1.05 = 762 . I guess your vertical sync is too short.
-
- In the directory /usr/lib/X11/doc/vgadbase you can find clocks for many
- ET4000 cards.
-
- Hope this helps
