Video Wall Controller for Four Displays

This LUOM 2x2 video wall controller splits a single HDMI or DVI source across four HDMI screens. It accepts 4K input at 30 Hz and 1080p at up to 60 Hz, then outputs 1080p to each display. The unit suits sports bars, schools, retail spaces and corporate lobbies that need one image spread over a 2x2 array.

Upgrade from Single-Screen Playback

Moving from a single display to a 2x2 video wall lets you show the same content at larger scale without buying a matrix switcher. The jump is worth it when you need eight display modes — including 1x2, 1x3, 1x4, 2x1, 3x1 and 4x1 — from one box. It is not for installations that require 4K output on each panel or more than four outputs.

Plug-and-Play Setup with Remote

Connect the source, attach four HDMI displays, add the 5 V 2.1 A power adapter and select a mode via the included remote. Audio can exit through a 3.5 mm jack for stereo or an optical SPDIF port for 5.1 surround. The metal case uses convection cooling, so keep ventilation slots clear. The remote ships without a battery, which is the most common oversight during first use.

Questions about this item

What mounting features does the controller chassis include?

The unit has a porous convection design for heat dissipation and a non-slip base so it sits stably on a flat surface without additional brackets.

Which step in the remote-control setup is most often missed?

Inserting a battery into the supplied remote control is required before it can switch the eight display modes; the battery is not included.

What ongoing maintenance does the controller need?

Keep the porous vents clear of dust to maintain convection cooling; no internal filters or user-serviceable parts are present.
