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.
