Triple-monitor KVM for three computers

The IHDAPP 303DH lets one keyboard, one mouse and three displays control three separate PCs or laptops. Each system connects through one HDMI and two DisplayPort inputs, while the switch outputs to three monitors and four USB 3.0 peripherals. It is built for users who need simultaneous extended or mirrored desktops across all three screens.

Build integration and cabling requirements

Every computer must provide one HDMI 2.1 and two DP 1.4 ports to drive the three monitor outputs. The unit ships with four USB 3.0 cables, a wired remote and a 12 V power adapter that must be connected for stable USB operation. No drivers are required; the switch enumerates as standard HID and video devices on Windows, macOS and Linux.

Sustained-operation behaviour

LED indicators show the active host at all times, and the wired remote allows switching without reaching the rear panel. The 5 Gbps USB 3.0 hub maintains throughput for keyboards, mice, printers or storage during long sessions. External power keeps the link stable when all three computers and four peripherals are active continuously.
