DVI-I Support
The DVI-I port supports both digital and analog DVI displays. The maximum
supported resolution is 2048 x 1536 at 75 Hz refresh rate (QXGA) for analog video and
1920 x 1200 at 60 Hz refresh rate (WUXGA) for digital video. DVI analog output from
the DVI-I connector can be converted to VGA with a DVI-I to VGA adapter.
When a non-video PCI Express add-in card is installed in the PCI Express x16
connector on the Desktop Board, the digital output of the DVI-I port is disabled.
HDMI* Technology Support
The HDMI port supports standard, enhanced, or high-definition video, plus multi-
channel digital audio on a single cable. It is compatible with all ATSC and DVB HDTV
standards and supports 8-channel digital audio. The HDMI port is compliant with the
HDMI 1.3 specification.
When a non-video PCI Express add-in card is installed in the PCI Express x16
connector on the Desktop Board, the HDMI port is disabled.
External PCI Express x16 Graphics
The GMCH supports an add-in PCI Express discrete graphics card via the PCI
Express 2.0 x16 connector as follows:
• Supports the PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (500 MB/s total). The maximum theoretical bandwidth on the interface is
4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when
operating in x16 mode.
• Supports the PCI Express 2.0 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (1000 MB/s total). The maximum theoretical bandwidth on the interface
is 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when
operating in x16 mode.
