1×4 HDMI Video Wall Controller for multi-screen

This controller takes a single HDMI or DVI source and splits it across four HDMI displays in a 2×2 arrangement. It is built for installers, retailers and event technicians who need one image stretched over four screens without a dedicated graphics card per display. The unit also offers eight splicing modes including 1×2, 1×3, 1×4 and mirrored layouts for flexible configurations.

Remote control and dual audio outputs change daily

A handheld remote lets you switch between the eight preset layouts without touching the box, while a 3.5 mm jack provides 2.0-channel audio and an optical SPDIF port delivers 5.1-channel sound. Both audio paths are extracted from the incoming HDMI stream, so external receivers or soundbars can be driven directly. The 5 V 2.1 A power adapter is included, removing the need for a separate supply.

Plug-and-play installation

The device requires no drivers; connect the source, four displays, power and optional audio, then select a mode via the remote or front-panel buttons. A porous chassis enables convection cooling, and non-slip feet keep the unit steady on a rack shelf or desk. Note that 180° rotation is only available in 2×2 mode, and output resolution is limited to 1920×1080 even when the input is 4K at 30 Hz.

Questions about this item

Does the 5 V 2.1 A power adapter need periodic replacement?

The included 5 V 2.1 A power adapter is a standard external supply; no scheduled replacement interval is defined by the manufacturer.

What resolution limit appears first when the four 1920×1080P outputs run continuously?

Output resolution is capped at 1920×1080P at 60 Hz, so that ceiling is reached before any input bandwidth limit.

How much fan noise or heat does the porous convection design produce during all-day operation?

The unit uses passive porous convection cooling with no fan, so it runs silently and stays warm to the touch under continuous load.
