Know what connects where.
Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
One source here. Another over there.
Route any connected input to any of the 4 outputs. Put a presentation on one screen and a separate feed on another, or send the same programme to every display without changing cables.
A place for 4K and Full HD screens
Output downscaling lets a supported 4K signal feed a 1080p screen while another output retains 4K. Downscaling changes resolution; it should not be treated as automatic HDR-to-SDR conversion.
Make sound and control part of the plan
Four optical outputs make it possible to break out audio for the corresponding display routes. This model does not provide ARC. Front buttons, IR, RS232, web interface and IP/Telnet control.
Make sure it fits your setup.
Independent sources
A matrix routes existing video signals. For different content on different screens, connect distinct sources or independent computer video outputs.
Mixed display formats
Match the source’s HDR, refresh rate and audio format to the destination equipment. Dolby Vision is not available in downscaling mode on the 4KMX44-H2.

A little clarity before you buy.
How is a matrix different from a splitter?
A splitter repeats one input on several outputs. A matrix can select a different input for each output.
Can it turn one PC output into separate extended desktops?
No. One HDMI input is one video signal. Independent desktop content needs separate graphics outputs from the computer.
Will optical output carry lossless Dolby TrueHD?
No. Optical audio is limited to supported stereo PCM and compressed surround formats. Use a suitable HDMI audio path for lossless formats.
