ID: Q167020

The information in this article applies to:

SYMPTOMS

The ATI Graphics Pro Turbo PCI video adapter seems to be detectable, but any screen resolution settings other than 640 x 480 are not retained after restarting the system. The settings revert to the 640 x 480 resolution.


CAUSE

The Windows NT 4.0 version of the ATI Graphics Pro Turbo PCI video adapter driver will only allow 640 x 480 display resolution.


RESOLUTION

Acquire the Windows NT driver version 3.1.76 or later display driver set from the ATI Web site.
