Introduction
With the DIGITUS® Video Wall Controller 2x2, you can transform a total of 4
TV sets or monitors with HDMI® into a large-format video wall. The controller
enables you to distribute a high-resolution 4K signal across 4 Full HD displays
to create a large image. You can be as creative as you like: set up a classic 2x2
monitor wall or arrange 2 to 4 monitors horizontally or vertically, combining
them to make a video wall. By pressing a button on the device or the remote
control included in delivery, you can switch between the different modes.
The device also contains a splitter function that allows you to display the
same image on all the monitors. With this professional tool, you are ideally
equipped to display visualizations of all kinds for trade fairs, advertising or
shop windows with a high degree of flexibility.

Troubleshooting
Problems
Causes
Solutions
Power light is off
and product is not
working
Is the power adapter properly
connected and the power
on/off button is on
Please check if the power
adapter is connected
properly and switch on the
power on/off button
The product
doesn’t show the
right image of the
Apple TV 4K or
other players
Maybe the customers setup
the wrong output signal
formats that the processor
can`t support, such as HDR10
(4K@60Hz 4:2:0) and Dolby
Vision (4K@60Hz 4:2:2), etc.
Please change the resolution
to the SDR resolution like
4K@60Hz RGB or 4:4:4，and
down compatible with the
lower SDR resolutions
No picture and
sounds after re-
plug the HDMI
cables or power
cable
Maybe the products can`t
recognize correctly signal of the
input and outputs after the
actions, or the connection of
the HDMI cables are not very
well
Please check the connection
of the HDMI cables and
power cable, and re-connect
the HDMI cables and have a
try, or change a high quality
HDMI cables
