The GBC 14.2811.30 HDMI Matrix 4x4 allows up to four sources — such as media players, PCs, or set-top boxes — to be routed independently to any of four displays simultaneously. Sources and destinations can be combined freely, so different rooms can show different content or the same source can appear on all screens at once.

The 18Gbps bandwidth supports 4K@60Hz HDR with 36-bit deep colour, HDCP 2.2 copy-protection, and EDID management. The Downscaling feature converts 4K signals so they display correctly on lower-resolution screens such as 1080p TVs. Both input and output cable runs support up to 5 m. The metal chassis weighs 535g and measures 220×205×19mm. Power supply 12V 2.5A and remote control are included.
