Rick,
Thanks for the reply. I'll check the heat on the chip when time
permits. Just fyi, I've tried different screen sizes via the
prev/next in xvidtune. All resolutions have some amount of jitter, etc.,
except the 1280x1024. Also, if I boot NT4.0 on the same box,
it handles 1600x1024 just fine.
Is there some way I could either duplicate the NT settings and/or
find a clock rate to use as an over-ride in the XF86Config file
that would work better? Not that I know what I'm talking about here...
Thanks,
k.
