Available Video Resolutions
The following table lists the available video resolutions using the current
drivers. The available resolutions may be different with later versions of
driver.
If Video Plug and Play is
enabled
in
Setup
, and a DDC monitor is detected,
Setup
will automatically configure the best refresh rate. For non DDC
monitors, or when video Plug and Play is
disabled
, refresh rates can be
changed in
Setup
.
The number of colors supported is limited by the graphics board and the
video RAM. The resolution/refresh-rate combination is limited by a
combination of the display, the graphics board, and the video RAM.
Connectors
The layout of the pins for the DB15 VGA socket is depicted on page 42.
The Video Electronics Standards Association (VESA) defines a standard
video connector, variously known as the VESA
feature
connector,
auxiliary
connector, or
pass-through
connector. This connector (whose
pin names are listed in a table on page 40) is integrated on the system board,
and is connected directly to the pixel data bus and the synchronization
signals.
The graphics controller supports an output-only VESA
feature
connector in
VGA mode. It is disabled by default and must be enabled in the
Setup
program. Use of the VESA feature connector will disable 1 MB of the video
memory; with access only to the remaining 1 MB of video memory, some of
the video resolutions will not be available.
