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. This driver release resolves an issue with 3D PRO TURBO 8MB products displaying only 640 X 480 resolution. The filename for the driver set is as specified below for the appropriate version of Windows NT:
   Windows NT 4.0   NT40-176.exe   Size: 499K   Date: 02-27-97
   Windows NT 3.51  NT351176.exe   Size: 486K   Date: 02-27-97
   Windows NT 3.5   NT35-176.exe   Size: 494K   Date: 02-27-97
				

For current installation instructions, also see the following files on the ATI Web site:
   Windows NT 4.0    NT40-176.txt
   Windows NT 3.51   NT351176.txt
   Windows NT 3.5    NT35-176.txt
