Overview

Most 4×4 matrix installations require a separate video wall processor — adding cost, rack space, and a second device to configure and control. The KanexPro MMX-4X4VW eliminates that by combining true 4×4 HDMI matrix switching with an integrated video wall processor in a compact half-rack unit, letting integrators route any of four sources to any of four displays while composing 2×2, 4×1, or 1×4 video wall layouts from a single device.

Seamless switching with no delay or image loss keeps transitions clean in live environments. Independent output scaling on all four channels ensures compatibility across mixed-resolution display installations without additional scalers. Control is straightforward — front panel buttons, IR remote, or RS-232 — making the MMX-4X4VW equally at home in a classroom, retail signage deployment, small boardroom, or hospitality venue where simplicity matters.

What does true 4x4 matrix switching mean on the MMX-4X4VW?

Any of the four HDMI inputs can be independently routed to any of the four HDMI outputs seamlessly, with no switching delay or image loss during transitions.

How many video wall layouts does the processor support?

The unit supports 10 display modes selectable via IR remote or RS-232 command, covering 2x2, 2x1, 2x1-2, 1x2, 1x2-2, 3x1, 4x1, 1x3, 1x4, and standard matrix mode.

How do I route a specific input to a specific output over RS-232?

Send 's in x av out y!' where x is the input (1-4) and y is the output (0-4, with 0 meaning all outputs). For example, 's in 1 av out 2!' routes input 1 to output 2. Commands end with an exclamation point delimiter.

How do I set per-input EDID over RS-232, including copying from a connected display?

Use 's edid in x from z!' where x is the input (0-4) and z selects the EDID source (1=4K30_444/2.0, 2=4K30_444/5.1, 3=1080p/2.0, 4=1080p/5.1, 5=1920x1200/2.0, 6=1360x768/2.0, 7=1024x768/2.0, or 8-11 to copy the EDID directly from OUT 1-4).

How is the MMX-4X4VW powered and what are its dimensions?

It runs on AC 100-240V 50/60Hz to DC 12V/1A (3.6W max), in a metal black half-rack enclosure measuring 8.66 in x 4.13 in x 0.75 in (220 x 105 x 19mm) and weighing 1.12 lbs (508g).

What is included in the box?

The package includes one 4K 4x4 HDMI Seamless Matrix Switcher and Video Wall Processor, one Matrix IR Remote, one 3-pin 3.5mm Phoenix connector, two mounting ears, four KM3x4 machine screws, one 12V/1A locking power adapter, and one user manual.

There is no picture on one output. What should I check?

Confirm the corresponding front-panel Signal Source LED for that output is lit green, verify the HDMI cable run is within 5m for 4K30 or 10m for 1080p 4:4:4, and check the configured resolution with the RS-232 command 'r output y res!'.

The video wall image is misaligned across displays with bezels. What should I check?

Use the H-BEZEL and V-BEZEL adjustment on the IR remote, or the RS-232 commands 's tw h bezel x!' and 's tw v bezel x!' (values 0-10), to compensate for the physical bezel gap between panels.

Why choose the MMX-4X4VW over separate matrix and video wall processor units?

It combines true 4x4 seamless matrix switching and a 10-mode video wall processor in one half-rack unit, eliminating the need for a dedicated external video wall processor alongside a matrix switch.

What space benefit does the half-rack form factor provide?

At 220 x 105 x 19mm in a compact half-rack chassis, the unit fits in space-constrained racks or AV furniture where a full-width matrix switcher would not.
