Four-Port HDMI 2.0 KVM Switch

This Corn Electronics KVM switch lets you control four computers using a single HDMI monitor, USB keyboard and USB mouse. It supports wireless keyboard and mouse receivers and includes a USB hub port for peripherals such as flash drives, scanners, 3D printers or monitor cameras. The unit is new and delivers 18 Gbps bandwidth for 4K resolution at 60 Hz with 4:4:4 chroma sampling. Physical buttons and keyboard hotkeys provide two ways to switch between the connected systems.

Suited for multi-system desks

The switch suits users who need to operate four PCs or laptops from one console in offices, teaching spaces, meeting rooms, home theatres or test benches. Wireless keyboard and mouse support adds convenience for living-room or presentation setups. Buyers who need to control more than four computers should look at a different solution. Anyone requiring video interfaces other than HDMI will need an alternative device.

18 Gbps bandwidth for 4K 60 Hz 4:4:4

The single specification that decides compatibility is the 18 Gbps bandwidth, which enables 4K resolution at 60 Hz with full 4:4:4 chroma sampling. This throughput also covers 3D formats and 1080p or lower resolutions. If your monitors or sources demand higher bandwidth than 18 Gbps, this switch will not meet the requirement.

Questions about this item

How can I confirm the KVM switch is passing a 4K 60 Hz signal correctly after connecting four computers?

Verify the monitor reports 4K at 60 Hz in its on-screen display and check that mouse movement feels responsive on each selected port with no visible lag or flicker.

Which cables and peripherals are included versus required separately for a four-PC setup?

The unit provides four HDMI 2.0 ports and USB hub ports for keyboard, mouse, and devices like a scanner or 3D printer; you must supply four HDMI cables and four USB host cables to link each computer.

How do I decide between using the front-panel button or the keyboard hot-key combination to switch ports?

Use the button for quick manual changes at the desk; use the Scroll Lock, Scroll Lock, number sequence or Ctrl, Ctrl, number sequence when you prefer to keep hands on the keyboard.
