Overview

The Cliqer 8K Video Wall Controller takes one 8K 60p HDMI 2.1 signal and splits it into four 4K outputs, pixel for pixel. Run an LED wall or a 2 × 2 display wall from one computer, every output on the same frame. It has two HDMI inputs, analogue audio out, and control from the front panel, RS232 or a web page on your network.

Connect it

1
Place or mount
Stand the box on a flat surface, or fit the two mounting ears for a shelf or rack tray. Leave space around it for air.
2
Connect the source
Run a certified Ultra High Speed HDMI cable from your computer or media server to HDMI IN1, and a second source to IN2 if you have one. Set the source to 7680 × 4320 at 60 Hz.
3
Connect the outputs
Run one cable from each of HDMI OUT1 to OUT4 to a display, a 2 × 2 display wall in its video wall mode, or an LED processor input.
4
Connect control (optional)
Plug in Ethernet for the web page and API, or RS232 for a show controller or control system.
5
Power on
Connect the 12 V adapter last. Turn on the displays, then the source.
6
Pick the input, set the bezels
INPUT SELECT switches between IN1 and IN2; the outputs go black for 2 to 3 seconds while they resync. H+, H-, V+ and V- line the picture up across the screen frames.

Control from a browser

1
Find the address

Open the page
Type the address into a browser with http:// in front, for example http://192.168.1.239.

The page has three tabs

Video Wall

Pick the input and its EDID, set the bezel crop and the area of the input to use (x1, y1 to x2, y2), and keep layouts in Presets 1 to 9. A mode sets its matching EDID.
