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 or 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:
