Video Function
The onboard video controller is capable not only of enhancing video
display, but supporting 3-D video applications as well. The video
controller features the Accelerated Graphics Port (AGP) design - the
latest bus architecture that is considered to be the best solution for 3-D
applications. AGP offers greater bandwidth; thus, it is capable of
speeding up the VGA bus in order to meet the requirement of 3-D
applications.
The board may come with 2-MB upgradable to 4-MB video memory.
Larger video memory allows you to display higher resolutions and
more colors.
The following table lists the video resolutions supported by the
onboard VGA:
