Monitor/VideoProblems
Q: The OSD menu does not display a “ “ on a channel where a computer is
connected and powered up.
A:
DKVM-16
updates “ “ every 2 seconds. Use the hot key to access
the OSD menu again and it should re-detect all the active channels.
Q: When cascading the MASTER unit does not see the slave unit(s).
A:
Refer to the Installation section for information on how to
properly connect the daisy-chain cable.
Make sure you are using the correct daisy-chain cable. Using
any other cable will not guarantee proper operation or video
quality.
Reset all the slave units first and then reset master unit to
recover the lost slave unit.
Although a power supply is not necessary to make the slave
unit work, try adding a power supply.

Q: I am getting ghost shadowing or fuzzy images on my monitor.
A:
Check the cables and make sure that they are connected prop-
erly.
Your resolution and/or refresh rate may be extremely high, or your
cable may be too long. Replace your VGA cables with coaxial,
double-shielded cables.
Check to make sure that the power adapter is plugged in and is
working properly. Make sure the power switch is on.
Lower your refresh rate and/or screen resolution settings.
