This article describes the hardware requirements for multiple-display support 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 be identical. Each video adapter and monitor combination is separately enumerated 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.
