Functional Description
10.5.3
Multiple Display Configurations
Microsoft Windows* 2000, Windows* XP, and Windows Vista* operating systems have
enabled support for multi-monitor display. Since the GMCH has several display ports
available for its two pipes, it can support up to two different images on different
display devices. Timings and resolutions for these two images may be different. The
GMCH supports Intel® Dual Display Clone, Intel® Dual Display Twin, Intel® Dual
Display Zoom, and Extended Desktop.
Intel Dual Display Clone uses both display pipes to drive the same content, at the
same resolution and color depth to two different displays. This configuration allows for
different refresh rates on each display.
Intel Dual Display Twin utilizes one of the display pipes to drive the same content, at
the same resolution, color depth, and refresh rates to two different displays.
Intel Dual Display Zoom uses both display pipes to drive different content, at
potentially different resolutions, refresh rates, and color depths to two different
displays. This configuration results in a portion of the primary display to be zoomed in
on and displayed on the secondary display.
Extended Desktop uses both display pipes to drive different content, at potentially
different resolutions, refresh rates, and color depths to two different displays. This
configuration allows for a larger Windows Desktop by using both displays as a work
surface.
Note: The GMCH is also incapable of operating in parallel with an external PCI Express
graphics device. The GMCH can, however, work in conjunction with a PCI graphics
adapter.
