4K Video Wall Controller for Multi-Screen Setups

The LUOM controller takes a single HDMI or DVI source and splits it across four HDMI displays in configurations such as 2x2, 1x3, or 4x1. It accepts input resolutions up to 3840x2160 at 30 Hz and outputs at 1920x1080. Audio is available through a 3.5 mm jack with 2.0 channel sound or an optical SPDIF port with 5.1 channel sound. The unit includes a remote control, a 5V/2.1A power adapter, and a user manual.

Installers Building Video Walls, Not General Users

This device suits installers creating digital signage or splicing screens where a single source must fill multiple panels with 180-degree rotation available in 2x2 mode. It does not suit buyers who need independent content on each screen, higher than 1080p output per display, or more than four outputs. Users requiring HDCP 2.2 handshake guarantees or seamless bezel correction should look at dedicated matrix processors instead.

Plug-and-Play Installation With Basic Cabling

Connect the source to the HDMI input, link up to four displays to the HDMI outputs, attach the power adapter, and select the splicing mode via the remote. The porous chassis provides convection cooling without fans. Common issues include mismatched EDID causing no signal on some outputs, audio defaulting to the wrong port, and the 30 Hz input limit causing judder with 50 or 60 Hz sources.

Questions about this item

What source device do I need to connect to the single HDMI input?

Any device with an HDMI or DVI output — such as a computer, media player, or games console — can drive the controller.

Can I keep my existing 1080p displays and still use the 4K 30Hz input capability?

Yes, the unit accepts 3840x2160 at 30 Hz and downscales each output to 1920x1080 for your current screens.

How do I confirm the 180-degree rotation is active on the 2x2 video wall?

Select 2x2 mode via the remote; each of the four output quadrants will then show its portion rotated 180 degrees.
