Hi,

I have 3, Dell Optiplex GX200 motherboards. Two were bought
in hopes of fixing an intermittent comport/keyboard lockup problem
in the original.

I plugged both of the replacement GX200 MB's into my system,
and they both have the same video problem, dark letters on a
light colored screen result in smears that go horizontally across
the screen. Also, colors like red are too intense.

The original MB doesn't have this problem. All were tested using
the same Dell Monitor, and using the same resolution, etc...
(eg. booted off of the same 'doze disk).

As far as I can determine, I have set up all three to the same
CMOS settings.

Anyone have any ideas?

Thanks!
