Four-computer KVM for triple DisplayPort setups

This KVM switch connects four computers to a single keyboard, mouse and three DisplayPort monitors. It suits professionals and enthusiasts who run multi-system workstations and need simultaneous extended, mirrored or spliced output across three screens. Each connected PC must support triple-display output for the switch to function as intended.

Sustained 8K and high-refresh operation

The switch handles continuous 8K resolution at 30 Hz and 4K at 144 Hz across all three outputs without throttling. DisplayPort 1.4 signalling maintains stable bandwidth during long sessions, while the three USB 3.0 ports sustain 5 Gbps data rates for attached peripherals. Audio and microphone channels remain active throughout switching cycles.

Passive cooling and clean cable routing

All video, USB and audio ports face the rear, keeping cables hidden and the desk tidy. The metal chassis dissipates heat from the 12 V power input without fans, so operation stays silent during extended use. Front-panel buttons and the included wired remote both show the active system via LED indicators.

Questions about this item

Does the 12-volt power supply run silently and stay cool during all-day use?

The unit draws 12 volts and has no fan listed, so it operates silently; heat output is low enough for continuous operation without active cooling.

Which cables must I already own to connect four computers to three DisplayPort monitors?

You need three DisplayPort 1.4 cables per computer and one USB cable per computer for keyboard and mouse sharing.

Will my older graphics card that only supports DisplayPort 1.2 still drive three 4K monitors through this switch?

Yes, the switch is backward compatible with DisplayPort 1.2, so a DP 1.2 card can run three 4K displays at supported refresh rates.
