This article describes the hardware requirements for multiple-displaysupport in Windows 98.
All of the video adapters that are used in a computer with multiple-display support must be Peripheral Component Interconnect (PCI) or Accelerated Graphics Port (AGP) devices that use multiple-display-enabled video adapter drivers that are included with Windows 98. Industry Standard Architecture (ISA) and Extended Industry Standard Architecture (EISA) video adapters are not supported.
The video adapters that are installed in your computer do not have to beidentical. Each video adapter and monitor combination is separatelyenumerated by Windows; you can configure each combination to use different screen resolutions and color depths. For example, you can set the primary adapter to 1024 X 768 pixels with 256 colors and the secondary adapter to 800 X 600 pixels with 32,000 colors.

Unsupported Video Adapter Chip Sets
You cannot use video adapters with the following chip sets as multiple-display support devices:
Permedia (this does not include the Permedia NT and Permedia-2 chip sets)
Supported Video Adapter Chip Sets
You can use any combination of the following supported PCI-based video adapters with multiple monitors. Only video adapters that are based on thefollowing chip sets work as primary and secondary video adapters.
Note that only the PCI adapters that are listed below are supported as the primary adapter. However, other PCI adapters may work even though they are not supported, but you must use the specified driver.
The following drivers are supported by Microsoft and are included on theWindows 98 CD-ROM:

S3 765 (Trio64V+) S3mm.drv (NOTE: Only certain updates work. These are the 40, 42, 43, 44, 52, 53, and 54 updates. If the adapter uses one of these updates, Windows 98 will recognize the video adapter as a Trio 64V+, provided the Microsoft driver is used. If the adapter does not use one of these updates, it is recognized as a Trio 32/64. Some OEM drivers can use any update. Be sure to note carefully which Microsoft driver Windows 98 selects when you use this adapter.)
