Apple Power Macintosh (7100 Series) - Manual (Page 89)

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:
1 Quit all application programs (save any open documents before quitting).
2 Be 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.
3 Choose Control Panels from the Apple ( K ) menu and open the Monitors control panel.
4 Click the picture that represents the monitor, and click Options.
