Cannot change display

Hi, I have an ATI graphics card/adapter/drivers installed. After a reinstall
I cannot install the display properly. Display will not change to ATI and 256
colors. I have tried to reinstall the drivers on numerous ocassions. The
display always says VGA and 16 colors. Now I found out the system is set up
for TWO MONITORS. Possibly, as I see it, the ATI adaptor is only on the
Monitor 2, not 1 and I cannot get rid of one of the monitors so as to only
install the ATI on one monitor that I am using.

The upshot is that I cannot use any graphics as they are all distorted due
to wrong resolution and colors due to using the wrong adaptor and drivers.

I would like to know what to do. Even these pages are often hard to read on
my monitor and this group so if you are willing to send a copy of the reply
to that might help me, although I will keep
trying to read this forum.
