4K 4×4 Seamless Matrix & Video Wall Processor

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.

Questions
- 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.
