In Windows 98 the PRIMARY display is the one that displays the LOGO when Windows starts. This PRIMARY monitor also shows the system BOOT messages. In addition to the standard 2D acceleration, the PRIMARY monitor also supports 3D (via Direct3D) and VIDEO (TV). FULL SCREEN DOS sessions are also locked to the PRIMARY display. The SECONDARY display adapter does NOT support: • DirectX • Direct3D • Multimedia video functions Here is a short list of applications you may encounter which will NOT currently function on a secondary display: • DVD Playback software • MPEG Playback software • Direct3D Games • Screen savers designed for a single-monitor setup • Any application that runs in a “fullscreen” mode Most of these applications will not function on a secondary display because the hardware and software features required (Direct3D, DirectDraw video acceleration, etc.) are ONLY available on the PRIMARY display adapter.
