Blackbird 4x2 HDMI Matrix 4K 60Hz

This Blackbird 4x2 HDMI matrix routes any of four HDMI sources to one or two displays. It complies with HDMI 2.0b and HDCP 2.2 and 1.4. The unit handles 18 Gbps bandwidth and video up to 4K at 60 Hz with YCbCr 4:4:4 colour.

Installers needing four inputs

The matrix suits installations that must switch four sources across two screens and extract audio from Output A to optical and analogue ports. Output B can scale 4K down to 1080p for older displays. Buyers who require more than four inputs or more than two independent outputs should consider a larger matrix.

16 EDID configurations for source compatibility

Smart EDID management provides 16 preset configurations so each connected source sees a supported display profile. This reduces handshake failures when mixing different source and sink devices. The feature is the primary specification that determines whether the matrix will work reliably in a given AV rack.

Questions about this item

How do I connect four sources and two displays to the 139667 matrix, and what step is often missed?

Connect each source to inputs 1–4 and each display to outputs A and B. The step often missed is selecting one of the 16 EDID presets so every source negotiates the correct 4K 60 Hz 4:4:4 signal.

Which parts of the 139667 matrix will need replacement or maintenance over time?

The internal power supply and the HDMI port contacts are the components most likely to degrade after extended use. The IR remote battery will also need periodic replacement.

What limit appears first when the 139667 matrix runs continuously at 4K 60 Hz?

The 18 Gbps bandwidth ceiling is reached first; sustained 4K 60 Hz 4:4:4 content uses the full data rate, leaving no headroom for additional overhead or longer cables.
