4K HDMI matrix switch for multi-source setups
This HDMI 2.0 matrix routes any of four sources to two independent displays at up to 4K@60Hz with 4:4:4 colour and 18Gbps bandwidth. It handles HDR10, HLG and Dolby Vision while letting each output show different or identical content. Ideal for installers and enthusiasts who need simultaneous 4K and 1080P playback across two zones.
Replaces basic splitters and single-zone switchers
A simple splitter duplicates one signal; this unit adds source selection, independent downscaling per output and audio extraction so each zone can run native resolution. The jump is worth it when you need true matrix routing, ARC return on output two and multi-channel audio de-embedding without adding separate converters.
RS-232 API and IR remote simplify integration
Front-panel buttons, an IR remote with system-code switching and a documented RS-232 API let advanced users automate control without IR conflicts. Common issues arise when the TV or receiver lacks ARC support or when both endpoints do not share Atmos capability, which breaks audio sync on output two.

Questions about this item
What physical space and connections does the 4x2 HDMI matrix need to fit and mount?
The unit requires four HDMI 2.0 inputs and two HDMI 2.0 outputs plus a 3.5 mm stereo jack, a Toslink S/PDIF port and an RS-232 connector on its rear panel; allow clearance for cable bend radius on each port.
How is the matrix installed and which step do users often miss?
Connect up to four HDMI sources to the inputs and two displays to the outputs, set the DIP switch on output 2 for ARC or de-embed mode, then press the remote's system-code button briefly so the IR remote does not clash with other gear.
What maintenance or replacement will the 4K@60Hz matrix need later?
The matrix has no user-serviceable parts; if a port fails or firmware updates are required, the whole unit must be replaced.
