This article describes switches that correct some display problems that can
occur in Microsoft Windows 95.
The [boot] section of the SYSTEM.INI file should contain the following line
for any Windows 95 version of a display driver:
The actual video driver (such as VGA.DRV or S3.DRV) is loaded from the
registry. This allows support for dockable personal computers that have
different adapters for the laptop versus the docking station.
Setting the monitor type in the display properties does not affect the
refresh rate output by your display adapter. To change this, you must run a
utility supplied by your display adapter manufacturer or computer
manufacturer. Some display utilities must be run in the AUTOEXEC.BAT file;
however, on other computers, display type is set in BIOS configuration
Examples of display utilities from adapter manufacturers include the
Cirrus Logic MONTYPE.EXE, CLMODE.EXE
Diamond Stealth STLMODE.EXE
Tseng Labs VMODE.EXE
Western Digital VGAMODE.EXE
The sections below describe different video cards and the requirements for
these drivers to work correctly in Windows 95.
ATI Mach 8/32/64
This adapter must be configured correctly using the ATI INSTALL.EXE program
for Windows 95 to use high-resolution modes properly. Correct setting of
your monitor type is especially important. This is because the high-
resolution modes may not be available for selection, or the computer may
fail when attempting to switch to that mode.
Compaq QVision 2000
These adapters use the Matrox MGA controller.
These adapters are supported with Windows 95 drivers. The VGA driver
is installed by Setup.
Diamond Stealth 64
For True Color support (16.7 million colors) add TrueColor=24 in the
[DISPLAY] section of the SYSTEM.INI
Setup preserves Microsoft Windows 3.1 drivers for this adapter when Setup
is run from within Windows 3.1. Setting up Windows 95 from MS-DOS causes
the Windows 95 VGA driver to be installed. If this occurs, the Diamond
Viper setup program should be used to install the Windows 3.1 drivers into
Windows 95. Copy the latest Viper files from the Drivers directory on the
Windows 95 CD.
This laptop uses Western Digital controllers. Older versions of these
laptops require the IBM VESA driver file to be loaded in Autoexec.bat
(Ibmvesa.com) or in Config.sys (Vesa.exe) for 256-color and high-resolution
modes to be supported by the Windows 95 Western Digital display driver.
Newer versions of these laptops do not require the use of the IBM VESA
S3-Based Video Adapters
Windows 95 provides a hardware acceleration slider that can be used to
correct graphics problems:
- If you have problems with your mouse pointer, disable the hardware
cursor by setting the slider to the Most setting.
- If you experience miscellaneous hangs with your S3 adapter, disable
memory-mapped I/O by setting the slider to the Basic setting.
- If you have problems with a modem on COM 4, please see the following
article in the Microsoft Knowledge Base:
S3 Video Driver Conflicts with COM4
If you continue to have problems, try the None setting.
For more information on how to use the slider to change the way
Windows 95 uses the video card, please see the following article in the
