Four-Port HDMI KVM Switch

The Corn Electronics switch lets one keyboard, mouse and monitor control four HDMI sources such as laptops, desktops or game consoles. It accepts four computer inputs and routes a single display output at resolutions up to 3840 x 2160 at 60 Hz with HDCP 2.2 support. The unit is aimed at users who need to manage multiple systems from a single desk without swapping cables.

Aluminium chassis with push-button and remote

The housing uses aluminium alloy for heat resistance and durability, while front-panel buttons and an included extension cable provide two ways to change the active host. Four integrated USB 2.0 hub ports allow shared peripherals such as printers or storage drives to stay connected. LED indicators show the selected port at a glance, and hot-plug support means devices can be added or removed without powering down.

Replaces manual cable swapping for multi-system

The switch removes the need to physically reconnect HDMI and USB cables each time you move between computers or consoles. It is a practical upgrade when desk space is limited and a single 4K display must serve several hosts. The jump is less worthwhile if you require keyboard hot-key switching or need USB 3.0 speeds for high-bandwidth peripherals.
