Quadra AV Monitors Extension

The Quadra AV Monitors Extension is an extension for use with Macintosh Quadra AV computers. It is mainly a bug fix to support the included graphics card capabilities which prevents the colors on monitors attached to Quadra AVs from being confused and messed up.

The extension describes the capabilities of the built-in video card for the Macintosh Quadra and Macintosh Centris AV computers.

If this file is removed, monitor options (such as gamma settings) may not be available, although you can still use the video card with your Mac and you can still switch between different numbers of colors displayed on your monitor.
