SERVSWITCH™
E. The CPU is sending video with sync on green, which the ServSwitch does not
currently support. Call Black Box for technical support.
F. If the video problem is not centered on the monitor, check the video strands of
your cables. Tighten any loose connections.
G. If no cable connectors are loose, begin swapping your cables one at a time. If
the problem goes away when you substitute a cable, the old cable is probably
defective.
H. If swapping cables doesn’t solve the problem, try plugging the CPU into a
different CPU port on the ServSwitch or submaster. If the problem goes away when
the CPU is connected to a different port, the old port is probably defective.

A. If you’re using XGA, you must use coaxial cables (see Section 4.1.3 and
Appendix B).
B. Check your video driver or control panel. It might not be set up correctly for
your desired resolution.

A. This can happen when no video is coming from the currently selected port or
CPU and the “Configure overlay: Resolution” setting is wrong. Set the resolution
properly (see Section 5.4.1.B).
B. The CPU is sending video with composite sync and the monitor only accepts
horizontal or vertical sync, or vice versa. Change the settings of the CPU or
monitor so that the two are compatible. If this is not possible, swap in a different
monitor that can handle all of your CPUs’ synchronization types.
C. The CPU is sending video with sync on green, which the ServSwitch does not
currently support. Call Black Box for technical support.

The usual cause of this problem is that the affected CPUs are set to load a Logitech
or other type of mouse driver when Windows starts up. Set the CPU to load the
generic Microsoft mouse driver instead.
