Three-computer triple-monitor KVM

The AUTYUE 303DH lets one keyboard, one mouse and three displays control three computers — two laptops and one desktop. It is built for users who switch between work and personal machines without unplugging cables. MST support allows each laptop to drive three screens through a single USB-C connection. The desktop uses one DisplayPort cable to feed all three monitors.

MST wiring and USB sharing

Each laptop connects with one USB-C cable; the desktop connects with one DisplayPort cable. Three monitor outputs accept HDMI, HDMI and DisplayPort plugs. Four USB 3.1 ports at 10 Gbps share keyboards, mice, printers or scanners across the active system. A 12 V DC adapter powers the switch. Switching is done by front-panel buttons or the included wired remote. LED indicators show the active computer.

4K 60 Hz headroom and macOS limit

Video runs at 4K 60 Hz across all three screens. Windows systems support both copy mode and advanced mode; macOS is restricted to copy mode only. DVI, VGA or HDMI-to-DisplayPort adapters are not recommended. The switch does not suit users who need more than three computers or who require advanced mode on macOS.

Questions about this item

Will the 4K@60Hz output stay stable during all-day operation?

The switch supports 4K@60Hz via MST and DisplayPort; sustained stability depends on your GPU’s MST implementation and cable quality.

Does the unit run hot or make noise when switching three computers continuously?

The compact 12 x 8 x 3 cm metal enclosure is passively cooled with no fan, so it stays silent and only warm to the touch.

Which cables must I already own to connect two laptops and one desktop to three monitors?

You need one DisplayPort cable for the desktop and two USB-C cables that carry DisplayPort Alt Mode for the laptops; three monitor cables (HDMI or DisplayPort) are also required.
