Four-computer HDMI KVM

The IHDAPP 4-Port HDMI USB KVM Switch lets one keyboard, one mouse and one monitor control four separate computers. It is built for offices, classrooms, meeting rooms, home theatres and test benches where multiple systems share a single console. No drivers are required on Windows 10, 8.1, 7, Vista, XP, macOS, Linux or Chrome OS. The front-panel button and the included wired remote both change the active system instantly.

Single console, four systems

Connect each computer to the switch with its own HDMI and USB cables, then run one HDMI cable from the switch output to the display. Four USB peripheral ports on the switch let the active computer use a printer, scanner, flash drive, barcode reader, webcam or external hard drive without re-plugging. A single power adapter keeps the switching circuitry stable across all four channels. The package supplies four matched USB cables so every host connection is ready immediately.

Bundled cables and remote

Four USB host cables, one power cable, a wired push-button remote and a printed manual ship in the box. The remote duplicates the front button so the switch can sit out of sight while the button stays on the desk. The manual walks through the four-step hook-up: link HDMI and USB from each PC, attach the monitor, plug peripherals, then press to swap. No software installation or firmware update is needed for basic operation.

Questions about this item

Does the 4K 60Hz output stay stable when I keep all four computers connected for hours?

The switch supports 4K at 60 Hz and is designed for smooth, steady signal transmission during extended sessions with all four ports active.

How much heat or fan noise does the unit produce when it runs continuously in a quiet office?

The device has no fan and draws power from the included cable, so it runs silently with only minimal warmth during all-day operation.

Do I need to supply my own HDMI cables to link each of the four computers to the switch?

The package includes four USB cables and a power cable; HDMI cables for the four computer inputs and the monitor output are not included.
