ive checked a riva128 vesa bios (3.0):
over this everything 60hz
below this doublescanned (400×300 – 800×600 etc)
my dell 2007fp shows every 200, 400 lines as 720×400 70hz.
can the ossc handle higher res inputs, eg 1280×1024?
i tried my display (lg 34uc88) with the nvidia control panel custom resolutions – it supports every modes from 50hz to 70hz. i did not think, it is so flexible.
