Triple-Monitor KVM for Three PCs

This KVM switch lets a single keyboard, mouse and three HDMI displays control three separate computers. Each system connects through one HDMI and two DisplayPort inputs plus a USB link. The unit targets professionals and creators who run multi-monitor workstations across several machines and want instant switching without software drivers.

Build Integration and Peripheral Sharing

The switch requires one HDMI cable, two DisplayPort cables and one USB cable from every computer, plus three HDMI cables to the monitors. A bundled 12 V DC adapter powers the unit. An integrated four-port USB 3.0 hub running at 5 Gbps lets all three systems share storage drives, printers or other peripherals without extra cabling.

Sustained Operation and Switching

Front-panel push buttons and a 1.5 m wired remote change the active computer while LEDs show the current source. Plug-and-play firmware keeps video stable at 8K 60 Hz or 4K 144 Hz during long sessions. The metal chassis measures 6.1 x 2.6 x 1.7 inches and runs without fan noise, making it suitable for quiet studios or offices where continuous uptime matters.
