Keep four Ultra HD sources moving to four displays without tying the room to a single signal path. The Gefen 4x4 Matrix for HDMI Black gives integrators a compact matrix switcher for routing up to four 4K x 2K or 1080p sources to up to four Ultra HD displays. It supports resolutions up to 3,840 x 2,160 at 30 Hz, making it a practical fit for conference rooms, digital signage, and multi-display presentation spaces where source-to-screen control matters. This model is designed for installations that need more than simple switching. Deep Color, 3DTV pass-through, and support for lossless audio formats help preserve the source experience across the signal chain. The black finish suits professional AV environments, while the compact form factor gives you a lighter alternative to larger rack-mounted matrixes when space and deployment speed matter. For teams specifying dependable HDMI distribution at a premium level, this matrix delivers the routing flexibility and signal integrity expected in commercial AV systems.
