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

The Splitter at the sending end has multiple RJ45 output connectors.

When a long CAT5 cable is plugged in any of the outputs, the Splitter

expects a Receiver at the other 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.

6. Poor audio quality at the Receiver

Only use powered speakers with the Receiver. It is also good practice

to set the audio level (volume) output of the PC about 1/2 to 2/3 from

the maximum and use the volume knob of the speakers to adjust the

volume to the desired level. A low volume signal output from the PC

reduces the signal-to-noise (S/N) ratio, whereas too high output

amplitude can cause saturation and clipping to occur.
