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). DVI analog output
can be converted to VGA with a DVI-to-VGA connector.
When a PCI Express x16, x8, or x4 add-in card is installed on the Desktop Board, the
DVI-I port is disabled.
