3. Shaking image or periodically blanking monitor
Although CAT5 cable uses twisted pairs to transmit the signals from the
splitter to the receivers to reduce the amount of EMI coupled noise
from other external sources, a strong electromagnetic noise field can
cause instability in the signal.
Usual sources of this form of noise coupling are high current AC lines
or other high-density data and/or control cables that run adjacent to and
parallel with a substantial length of the CAT5 cable. To eliminate this,
either place a distance between the CAT5 cables from the splitter and
the interfering source, or use shielded CAT5 cables. Note that
separating the CAT5 cable from the EMI source by a few inches is
often sufficient to eliminate this problem.
4. The PC does not recognize a Plug-and-Play monitor
If the PC’s Operating System is setup to detect a plug-and-play monitor
(usually in Display Properties Advanced Settings), it may have trouble
finding a monitor if no local monitor is hooked up to the splitter. Only
the ID information of the local monitor is passed to the PC. If the PC
does not produce an image due to this, either connect a monitor to the
local VGA output port, or disable the plug-and-play monitor detection
in the PC’s operating system.
5. Faint shadows or ghosts at the remote monitor
Your splitter has multiple RJ45 output connectors. When a long CAT5
cable is plugged in any of the outputs, the unit expects a receiver unit at
the far end for proper termination. Therefore it is a good idea to unplug
the un-terminated CAT5 cables from the splitter unit. Please refer to
item 1 above for other possible causes.
