Power Macintosh 9500 Series: Video Card Scan Rates

This article describes the video scan rates for the Apple Accelerated Graphics card that ships with the Power Macintosh 9500 Series computers.
The Power Macintosh 9500 Series computers include the Apple Accelerated Graphics Card, based on the mach64 Graphics Accelerator card from ATI Technologies, Inc. The card normally includes 2MB of VRAM (expandable to 4MB via a 2MB VRAM daughter board) and supports resolutions from 512 x 384 to 1,280 x 1,024. The Monitors control panel reads the display sense codes and may not show every scan rate listed below.

Following are the video scan rates supported by the Apple Accelerated Graphics card in the Macintosh 9500/120:
