I'm glad to hear that someone out there has a similar problem. I'm running
with a Dell (Paradise video) and their utilities and drivers (except for
the Windows 800x600x16). With resolutions 800x600 and above, I've been
having incredible problems when I set the Vertical frequency of the
monitor to a higher rate than "standard VGA". If I go to 60 Hz, then I can
go into a DOS prompt and back out (windowing it or exiting it) and
everything's fine. But if I make it full screen, the monitor makes an
audible click and the screen stretches horizontally and shrinks vertically
back at the prompt. The same thing happens if I do a Ctrl-Alt-Del in
windows and the blue screen comes up; it too is distorted.

When I boost the frequency even higher, then I have exactly the same
problem Mr Yeo has. When coming back in to Windows the screen is screwed
up. More precisely, the picture flickers *extremely* badly, like there was
a solid black frame in there.

Interestinly enough, the problems go away when I switch to the Dell 256
color mode driver. Except when I go to a higher frequency. Then the
Windows screen looks "sheared". Everything has a horrible ghost image.

At 1024x768, everything's fine.

Has anyone run into problems like this? Or better yet -- answers? I called
Dell support and they said to run it at a lower frequency. Big help.

Thanks,
Danek
