AUTYUE KC-403DH KVM Switch

This AUTYUE KC-403DH KVM switch lets you control four computers using one keyboard, one mouse and three monitors. It supports extended mode for three independent screens or mirror mode for three identical screens. Four USB 3.0 ports share peripherals such as printers or flash drives at 5 Gbps. A wired remote controller is included for convenient switching.

Check cables and video outputs before ordering

Each connected computer must provide one HDMI output and two DisplayPort outputs plus one USB port. You need to supply three HDMI 2.1 cables and six DP 1.4 cables; shorter cables are recommended for signal quality. Verify that your monitors accept HDMI or DisplayPort inputs matching the switch ports. The unit includes a 12 V power adapter and four USB 3.0 cables for the computer links.

Thermals noise and power draw in normal use

The switch operates from the included 12 V power adapter and requires no additional power supply. It has no internal fan, so it runs silently during typical office or multimedia use. The compact enclosure measures 5.51 x 2.76 x 1.97 inches and stays cool under normal switching loads. Power consumption is limited to the adapter rating and the connected USB peripherals.

Questions about this item

What cables come in the box and which ones must I buy separately?

The box includes four USB 3.0 cables, a wired remote controller, a user manual and a 12 V power adapter. You must supply one HDMI 2.1 cable and two DP 1.4 cables per computer yourself.

Should I choose the 8K 60 Hz or 4K 144 Hz mode for my monitors?

The switch supports both 8K at 60 Hz and 4K at 144 Hz; pick 8K 60 Hz for maximum pixel count or 4K 144 Hz for higher refresh rate, matching your monitor's native capability.

What does the 8K 60 Hz rating mean when the switch is running three screens at once?

Each of the three outputs can deliver up to 8K at 60 Hz simultaneously, provided every computer and cable meets the HDMI 2.1 or DP 1.4 spec.
