4-Port HDMI KVM Switch for Four Computers

The TRENDnet AO-401A-US-3 lets you control four computers from a single monitor, keyboard and mouse. It supports 4K resolution at 60 Hz and 2K at 120 Hz for sharp visuals. Four USB 3.0 ports share peripherals at up to 5 Gbps data rates. EDID simulation keeps window layouts intact when switching between systems.

Suited for Multi-System Desks Not for Laptop-Only

This switch fits professionals who run multiple desktops or servers and need one console. It includes a wired remote and front push-buttons for instant source changes. Built-in cables simplify installation on a crowded bench. Users with only USB-C laptops or a requirement for more than four video inputs should consider other solutions.

Handles Four 4K Sources with USB 3.0 Bandwidth

Each connected computer can output 4K at 60 Hz without signal degradation. The USB 3.0 hub moves files from attached drives at SuperSpeed rates while remaining backward compatible. EDID emulation prevents resolution resets during switching. The unit does not support 8K video or more than four simultaneous computer connections.

Questions about this item

Do I need to supply my own HDMI and USB cables, or are they included with the AO-401A-US-3?

The package includes four USB 3.0 cables at 1.5 m each, one HDMI 2.0 cable at 1.5 m, and a wired remote control, so no extra cables are required for a basic four-computer setup.

Will my USB 2.0 keyboard and mouse still function through the USB 3.0 ports on this KVM?

Yes, the USB 3.0 ports are backward compatible with USB 2.0 and USB 1.1 devices, so existing keyboards, mice, and other peripherals will work without replacement.

How can I verify the EDID simulation is keeping each computer's display layout intact when I switch?

Switch between computers using the front-panel buttons or wired remote; if each system returns to its previous window arrangement and resolution without rearrangement, the EDID simulation is functioning as intended.
