quest:
(It goes without saying that your monitor supports the 1900 x 1200
resolution, right?)
The following may not resolve your problem, but let me mention it anyway...
We have also run into driver issues re a couple of PowerColor graphics cards
we've worked with, although not the same model you have. The problems we
encountered weren't precisely the same as yours but did involve driver
issues even when we installed the latest ATI driver as well as the driver
from PC's installation CD.
Anyway, try this in the meantime, assuming you haven't already done so...
Access
http://www.powercolor.com/Global/sup...ProductID=1362
and download/install the XP driver for your card. Do so even if the version
(8.52) is presumably the same version on the PC driver CD or earlier than
the one you've already installed via ATI.
It would probably be best to uninstall the present ATI drivers and whatever
other ATI-based software programs are listed from Add or Remove Programs
before installing the v8.52 driver.
While I'm not terribly sanguine about all this correcting the problem, it's
worth a shot.
