Triple-Monitor KVM for Two PCs

This KVM switch connects two computers to three monitors using two DisplayPort and one HDMI output per system. One keyboard and mouse set controls both PCs, with support for duplicate or extended desktop modes across all three screens. It suits users who need simultaneous multi-monitor access to a pair of workstations or laptops.

Sustained 8K60 and 4K120 Operation

The unit maintains video signals up to 8K at 60 Hz and 4K at 120 Hz without an external power supply for the video path. A 12 V DC adapter is included to provide stable power for the four USB 3.0 ports when high-draw peripherals are attached. LED indicators show the active computer, and switching via front-panel buttons or the wired remote occurs without perceptible delay during extended sessions.

Check Graphics Outputs and OS Compatibility

Each computer must provide two DisplayPort and one HDMI output to drive all three monitors in extended mode. The switch works with Windows, macOS, Linux and Unix systems without driver installation. It is not suited for PCs that lack the required video ports or for users who need more than two connected computers.

Questions about this item

Does the 12 V power adapter mean the switch runs hot or makes noise when it drives three 8K monitors all day?

The unit needs only the supplied 12 V adapter, has no fan and no moving parts, so it stays silent and cool even at full 8K@60 Hz load.

My laptops each have one HDMI and two DisplayPort outputs — is that enough to use all three monitor ports?

Yes, each computer must provide one HDMI and two DisplayPort connections, which matches the switch inputs exactly.

Will the USB 3.0 ports still run at 5 Gbps when I switch between a Windows desktop and a MacBook Pro?

The four USB 3.0 ports keep 5 Gbps speed on any supported OS — Windows, macOS, Linux or Unix — with no driver install required.
