Triple-monitor KVM for three computers

This KVM switch lets three computers share three monitors and four USB 3.0 peripherals. It accepts one HDMI and two DisplayPort connections per system and supports both extended and mirrored desktop modes. Driver-free operation works with Windows, macOS, Linux, Unix and Ubuntu. The unit includes a wired remote and front-panel buttons for instant switching.

Upgrade from single-display or dual-system switches

Replacing a single-monitor KVM or a two-computer switch removes the need to swap cables when moving between three workstations. The jump is worthwhile when each computer already provides one HDMI and two DisplayPort outputs; otherwise adapters or docking stations are required to fill the missing video ports. Integrated 5 Gbps USB 3.0 ports keep keyboards, mice, printers and flash drives accessible across all systems.

Limits of HDMI 2.1 and DisplayPort 1.4

HDMI 2.1 reaches 8K at 60 Hz and 4K at 120 Hz, while DisplayPort 1.4 tops out at 8K 30 Hz and 4K 144 Hz. Higher refresh rates or resolutions beyond those figures are not supported. Each computer must supply one HDMI and two DisplayPort signals natively or through compatible adapters to drive three displays simultaneously.

Questions about this item

What cables does each computer need to connect for triple-monitor output?

Each PC requires one HDMI 2.1 cable, two DisplayPort 1.4 cables, and one USB 3.0 cable to drive three screens properly.

How do I switch between the three computers, and what step is often missed?

Use the front-panel buttons or the included wired remote; the step often missed is connecting the USB 3.0 cable from each PC so keyboard and mouse switching works.

When should I replace the external power adapter?

Replace the adapter if the unit loses video on all three monitors or USB devices disconnect while the LED indicators stay dark.
