Troubleshooting
Please check that all monitor and USB cable connections are firmly connected to ensure
correct operation of the KVM switch.
No video displayed:
1. If the KVM Switch reacts to the universal hotkey with a beep signal, but no monitor picture is
displayed, please check if the currently selected computer is in sleep mode or powered down.
2. Please use high quality video cables as short as possible and for HDMI and DP not longer
than 2m. The KVM Switch should be the same video interface as the monitor (and the graphics
card). Using different interfaces and adapter cables may cause unpredictable incompatibilities,
especially for HDMI monitors using a DVI KVM Switch.
3. HDMI monitors on DVI KVM Switches: HDMI monitors provide EDID information to the
computer allowing the graphics card to output higher resolution and colour mode/depth signals
than supported by the DVI-D KVM Switch. The KVM Switch cannot support these signals and
will not show any picture unless the graphics card signal gets restricted to DVI-D compatible
signals, max. 1920x1200@60Hz RGB.
4. DP KVM Switch: When using highest resolutions like 4K @ 60Hz only short 1m high quality
DP cables can be used for reliable operation on powerful graphics cards. DP++ passive
protocol converters may be supported using max. 1m length monitor cables. Active protocol
converters and MST Hubs are not supported.
USB problems:
A computer boots but the keyboard or mouse or device doesn't work:
a. DO NOT SWITCH PORTS until the USB driver installations are complete! Equally
do not press any keys on the keyboard or mouse whilst a selected computer is
booting up.
b. Connect the keyboard and mouse or device directly to the computer and check the
status of the installed drivers. Once drivers are installed the devices also should
work when connected to the KVM switch.
