The purpose of the Basic Color Monitor system extension is to eliminate the problem that Macintosh Quadra 700, 800, 900, and 950 and Macintosh Centris 610 and 650 users may have with overly green screen color on the Apple Basic Color Monitor and some non-Apple VGA (Video Graphics Array) monitors. The Basic Color Monitor system extension may cause some non-Apple VGA monitors to go blank. If this happens, you need to disable the extension.
