My xorg.conf config says:
HorizSync 15 - 50
VertRefresh 50 - 50
ModeLine "800x600x50" 33.1584 800 840 968 1056 600 601 605 628
And the logfile:
(II) fglrx(0): Supported VESA Video Modes:
(II) fglrx(0): 640x480 at 60Hz
(II) fglrx(0): 800x600 at 60Hz
(II) fglrx(0): 1024x768 at 60Hz
(**) fglrx(0): *Mode "800x600x50": 40.0 MHz (scaled from 0.0 MHz), 37.9
kHz, 60.0 Hz
(II) fglrx(0): Modeline "800x600x50" 40.00 800 840 968 1056 600 601
This looks like 60Hz is used. And i'm not able to use the bob
deinterlacing and i think these are connected.
