Triple HDMI + Dual DP KVM for 3 PCs

This KVM switch connects three computers to three HDMI monitors using a mix of HDMI 2.1 and DisplayPort 1.4 inputs. Each PC requires one HDMI and two DisplayPort cables plus a USB link. Four USB 3.0 ports share peripherals at up to 5 Gbps. A 1.5 m wired remote and front-panel buttons both change the active system.

Suits multi-system desks with triple HDMI screens

Ideal for users running three PCs, laptops or consoles that output HDMI or DisplayPort and need simultaneous keyboard, mouse and monitor switching. Driver-free operation covers Windows, macOS, Linux and Chrome OS. Not suited for setups that require DisplayPort monitor outputs or more than four shared USB devices.

All three monitor ports deliver 8K 60 Hz

Every HDMI output supports 8K at 60 Hz, 4K at 144 Hz, 120 Hz and 60 Hz, plus 2K at 165 Hz. The unit ships with a 12 V DC adapter, three USB cables and the wired remote. Dimensions are 15.5 x 6.5 x 3 centimetres and weight is 0.84 lb.
