IHDAPP KVM303 Triple Monitor KVM Switch 3×3 8K60 4K144 4×USB 3.0

Triple-monitor KVM for three PCs

The IHDAPP KVM303 lets one keyboard, mouse and three displays control three computers or laptops. Each system connects through one HDMI 2.1 and two DisplayPort 1.4 links plus a USB 3.0 cable. The switch handles 8K at 60 Hz and 4K at 144 Hz while passing through four USB 3.0 ports at 5 Gbps for peripherals and storage.

Passive cooling with external power

The unit runs from a supplied 12 V DC adapter and has no internal fan, so it adds no audible noise to a desk. Power draw stays low because the switch only routes signals rather than processing video. The aluminium enclosure measures 16.2 by 6.5 by 4.3 centimetres and weighs 450 g, dissipating warmth through its surface.

Replaces separate switch and USB hub setups

Users moving from a basic two-port KVM or from juggling cables between machines gain simultaneous three-monitor extended or mirrored desktops and shared high-speed USB devices in one box. The upgrade makes sense when a workflow demands three synchronized displays across three hosts; it does not suit buyers who need hotkey switching, more than three computers, or monitors without DisplayPort 1.4 and HDMI 2.1 inputs.
