Four-Computer HDMI KVM Switch

This HDMI KVM switch lets you control four computers from a single monitor, keyboard and mouse. It supports video up to 3840 x 2160 at 30 Hz and adds three USB 2.0 ports for shared peripherals such as a printer or flash drive. The package includes a desktop controller for convenient switching.

Plug-and-Play Installation

No driver software is required; simply connect the four supplied 1.5 m HDMI cables with integrated USB pigtails to each computer and the switch is ready to use. A common mistake is inserting the HDMI and USB connectors the wrong way round — follow the cable labelling to avoid a blank screen or unrecognised peripherals.

Check Your Source Ports and Resolution

Verify that each computer provides an HDMI output and a spare USB port for the combined cable. The switch tops out at 30 Hz at 3840 x 2160, so systems set to higher refresh rates at that resolution will need to be lowered. Ensure your monitor accepts the chosen resolution and refresh rate before ordering.
