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 S3 README file that is provided on the Ready-to-Configure Utility Program CD for your computer for information on the refresh rates supported by your monitor and the video controller in your computer. (There are several S3 README files on the CD; use the one that corresponds to your operating system.) Important: 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. See the S3 README file for instructions. 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 "External connectors" on page 14. 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 "Setting power management features" on page 76). If the problem cannot be isolated and corrected, have the computer serviced. Chapter 7. Solving problems 129
