Four-by-Four HDMI Matrix

The Monoprice Blackbird 4K 4x4 HDMI Matrix routes four HDMI sources to four independent displays. Each output can show any source without mirroring. It handles video up to 4K at 60Hz with 18Gbps bandwidth and HDCP 2.2 compliance. Installers and multi-room AV systems gain flexible distribution from a single rack unit.

Sustained 4K Signal Distribution

The 18Gbps bandwidth maintains 4K at 60Hz across all four outputs continuously, not just in short bursts. Deep color up to 16-bits per channel and 3D video pass through without compression. HDCP 2.2 handshake remains stable during extended sessions, preventing signal drops when switching sources. Independent EDID management per input keeps each source configured correctly over long runs.

Build and Daily Connectivity

Front-panel LCD and menu system give immediate status and EDID control without a PC. RS-232 and Ethernet ports enable automated control system integration for scheduled switching. Each HDMI output includes a coaxial S/PDIF and 3.5 mm TRS analog audio breakout for zone amplifiers or powered speakers. Rack-mountable metal chassis fits standard AV furniture and stays cool during continuous operation.

Questions about this item

Does the Blackbird 115750 matrix generate noticeable heat or noise when running continuously?

The specifications list no fan, so the unit operates silently; its 18Gbps bandwidth handles 4K@60Hz signals without active cooling mentioned.

What cables or source devices must I already have to use the four HDMI inputs and four outputs?

You need up to four HDMI source devices such as players or consoles and up to four HDMI displays; the matrix itself provides the 18Gbps switching and HDCP 2.2 handshake.

Will my older 1080p@60Hz sources and displays work correctly through this 4K matrix?

Yes, the matrix supports resolutions up to 1080p@60Hz and 4K@30Hz, so legacy 1080p gear connects and switches alongside 4K equipment.
