4K60 Dual-Head KVM Switch for Four Computers

This Black Box KVM switch lets one dual-monitor workstation control four separate computers. It supports 4K resolution at 60 Hz across two HDMI displays per system. The unit suits professionals who need to manage multiple PCs or servers from a single keyboard, mouse and dual-screen setup without software latency.

Dual 4K60 HDMI video per port

Each of the four computer ports delivers two independent HDMI outputs locked to 4K at 60 Hz. This dual-head bandwidth is the specification that determines whether the switch matches a user's monitor arrangement; single-head or lower-refresh setups will not use the full capability.

Fanless metal chassis runs silently

The switch operates without fans, drawing power from an external 12 VDC, 3 A adapter that accepts 100-240 VAC. Rated MTBF is 58,618 hours at up to 7,000 feet altitude and 5 to 90 % non-condensing humidity, so normal office use adds no audible noise or thermal load.
