Monitor Termination Switches
Most SGI monitors witp BNC input connectors have impedane switches used to
tcxminate the video signals. These tennination switches are a push-button. toggle
type usually located under each BNC connector. Switches can be set in the
following two positions:
When the switch is in the "in" position (75 ohm), the signal is terminated.
When the switch is in the "out"p0sition (High), the signal is not terminated.
For single-monitor systems. all switches should be set in the "in" position so that
video signals are terminated With daisythained monitors, only the last monitor
should be
terminated.
If a monitor is incorrectly terminated the color may be incorrect or the video
display
may be distorted. When troubleshooting a monitor problem, make sure the
tcxmination switches
arc set correctly, depending on the specific configuration..
