Troubleshooting | Apple 7100 guide

You see wavy lines or static after switching to a television from a monitor connected to the second monitor port.

If the regular (RGB) monitor is still connected, switch back to it. If the monitor is no longer connected, or you can’t switch back to it, restart your computer. The next time you want to switch to a television, follow these steps:

1Quit all application programs (save any open documents before quitting).

2Be sure both the television and the monitor are connected to your computer.

If the television is not connected, shut down your computer and then connect the television.

3Choose Control Panels from the Apple (K) menu and open the Monitors control panel.

4Click the picture that represents the monitor, and click Options.

Click here to identify which picture represents the television.

Click the picture that represents the television, then click Options above.
