Power Macintosh: 8■24 GC Video Needs New Monitors CDEV

I have a Power Macintosh 8100/80 with an 8*24 GC card connected to an Apple TwoðPage Mono Monitor, and internal video card connected to an Apple 16-in Color monitor. When I restart the monitor, the Two-Page Monitor defaults to black and white. Resetting PRAM and doing a clean installation of system software has not corrected the problem.
The problem is caused by the version of the Monitors Control Panel. Installing v7.3.2 (or newer) of the Monitors Control Panel corrects this problem. You can find the correct version of the Monitors Control Panel on the Apple Multiple Scan Display Software Disk.

You do not need to go through the entire installation process to correct this problem. Simply drag the Monitors Control Panel from the Apple Multiple Scan Display Software Disk to your System folder.
