Cannot Use High-Resolution Modes with ATI Mach-Series Cards (120038)
The information in this article applies to:
- Microsoft Windows 95
- Microsoft Windows 98
This article was previously published under Q120038 SYMPTOMS
When you are using an ATI Pro Turbo series, Mach8, Mach32, or Mach64
graphics adapter and Windows is installed with the default 640 x 480
video resolution, after you change the video resolution using the Change
Display Type dialog box, Windows still starts up with 640 x 480
resolution. (To locate the Change Display Type dialog box, click Display in
Control Panel, click the Settings tab, and then click the Change Display
Type button.)
CAUSE
If Windows detects that the video card is unable to display in the
resolution selected, Windows defaults to 640 x 480 resolution. Windows
does this as a safety measure to prevent the system from starting up
with an unreadable image on the display.
RESOLUTION
To use 800 x 600 or an even higher-resolution video mode with the ATI
Mach8, Mach32, or Mach64 video card, you must first configure the ATI card
for the correct monitor type. This is done using the INSTALL.EXE program
found on the disks provided with the ATI video adapters.
