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 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:
