Dual-PC HDMI KVM with Integrated Cables

The Corn Electronics 21HUB is a compact two-port KVM switch that lets one USB keyboard, mouse and HDMI monitor control two computers. Integrated cables reduce desktop clutter and the unit draws power from the USB connection, so no external adapter is required. A wired remote button on a 1.2 metre cable provides instant switching without hotkeys.

Upgrade from Manual Cable Swapping

This switch replaces the need to physically unplug and reconnect HDMI and USB cables when moving between a desktop and a laptop. The jump is worth it when you share a single 4K display and prefer a tidy, permanent wiring layout. It also adds USB 2.0 peripheral sharing through the mouse port when a powered hub is attached.

Stable Operation Under Continuous Use

The HDMI 1.4a link maintains 4K×2K at 30 Hz during extended sessions without signal drops. USB-powered operation keeps the unit cool and eliminates wall-wart heat buildup. Manual EDID handling ensures the monitor handshake remains consistent across repeated switches.

Questions about this item

What cable lengths are built into the 21HUB for the two computers?

The switch has moulded-in cables for both computers; the remote push-button cable is 1.2 metre (3.9 ft) long so you can place the button where it is easy to reach.

How do I switch between the two connected computers?

Press the button on the 1.2 m wired remote — the 21HUB uses manual button switching only, with no hotkey combination required.

Can I add more USB peripherals later, and what port do I use?

Yes — plug a powered USB 2.0 hub into the mouse port on the console side to share printers, scanners or flash drives between both computers.
