The information in this article applies to:

- Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 
- Microsoft Windows NT Server versions 3.5, 3.51, 4.0 
-------------------------------------------------------------------------------

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.

  http://support.atitech.ca/drivers/drivers.html

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:
