MATRIX SERVSWITCH™
Your monitor display is fuzzy.
A. Check the settings of your monitor, especially the sharpness control.
B. If you can’t solve the problem by changing the monitor settings, you might have
run cable too far; maximum distance of original Serv type CPU or User Cable (not
including Expansion Cable) from any CPU to the shared monitor, keyboard, and
mouse is 25 ft. (7.6 m)—or less, if you are using SVGA video. You might need to
upgrade from original Serv cables to coaxial cables that carry the video signal
better. If you are already using coax cables, you might need to add Station
Extenders (our product codes AC253 etc.) or CAT5 KVM Extenders (our
ACU1000 and ACU3000 series of product codes); call Black Box for technical
support. See Section 3.2.3 and Appendix B.
Your video is not synchronized or is the wrong color.
A. Check the settings of your monitor, especially the sync or color controls.
B. Your monitor might not be capable of synching to the selected video resolution
or frequency (refresh rate). Try a lower resolution or frequency or a more
powerful monitor.
C. There might be a sync mismatch between a CPU and the monitor; for example,
perhaps the CPU is sending video with composite sync or sync on green and the
monitor only accepts horizontal or vertical sync. 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.
D. If the video problem is not centered on the monitor itself, check the monitor
cable and the video strand of the CPU Cable. Tighten any loose connections
.
E. 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.
F. If swapping cables doesn’t solve the problem, try plugging the CPU into a
different CPU port on the Matrix ServSwitch. If the problem goes away when the
CPU is connected to a different port, the old port is probably defective.
