TRENDnet ATLAHETUSSW220 Dual Monitor KVM Switch 4K 60Hz 2 Port HDMI 4 USB 3.0

Dual-Monitor 4K KVM Switch

The ATLAHETUSSW220 lets one keyboard, one mouse and two displays control two separate computers. It supports both duplicate and extended desktop modes so each system can show different content or mirror the same image. Four USB 3.0 ports share peripherals such as printers or storage at up to 5 Gbps. The unit draws power from the included 12 V adapter when high-draw devices are connected.

Verify Host Ports And Cables

Each computer must provide at least two HDMI outputs and every monitor needs at least one HDMI input to use the dual-display modes. All HDMI cables and the source graphics hardware must support 4K at 60 Hz to reach the stated resolution. USB peripherals require a standard USB receiver that plugs into the switch; devices without a receiver will not work. The package includes 15 cm USB 3.0 cables for the computer links.

Sustained Operation With External Power

Under continuous multi-monitor workloads the switch relies on the 12 V power supply to maintain stable USB 3.0 throughput and video signal integrity. Without the adapter, high-power peripherals may cause intermittent disconnects during long sessions. The push-button and wired remote switching methods introduce no measurable latency when toggling between systems. Heat remains low because the unit has no active cooling and no internal power conversion beyond the external brick.
