Monitor Problems Screen flickers. The monitor works when you turn on the system, but goes blank when you start some application programs. The monitor works when you turn on the system, but goes blank after some period of computer inactivity. Action Set the monitor for the highest, noninterlaced refresh rate supported by the monitor and the video controller in your computer. Refer to the documentation that comes with your monitor and the Matrox README file that is provided on the Ready-to-Configure CD that comes with your computer for information on the refresh rates supported by your monitor and the video controller in your computer. (There are several Matrox README files on the CD; use the one that corresponds to your operating system. When you open the appropriate README file, a prompt might appear requesting you to specify Mystique or Millennium. Specify Mystique.) Attention: Using a resolution or refresh rate that is not supported by your monitor might damage it. You can reset the refresh rate through your operating system. Instructions for doing this are included in the Matrox README file that corresponds to your operating system, which is provided on the Ready-to-Configure CD. Refer to your operating-system documentation for further information on monitor settings. If this does not correct the problem, have the monitor and computer serviced. Verify that: 1. The monitor signal cable is securely connected to the monitor and the monitor connector on the computer. For the location of the monitor connector, see "Connectivity" on page 10. 2. The necessary device drivers for the application programs are installed. If the problem cannot be isolated and corrected, have the monitor and computer serviced. The computer is probably set for energy savings with the Advanced Power Management (APM) feature. If the APM feature is enabled, disabling APM or changing APM settings might solve the problem (see "Advanced Power Management" on page 49). If the problem cannot be isolated and corrected, have the computer serviced. 88 Using Your Personal Computer
