GREATHTEK 4-Port KVM Switch, 4K@60Hz, HDMI, DisplayPort & USB-C

Mixed video inputs let this KVM switch connect different types of computers to one shared monitor. Control up to four computers using one keyboard and mouse, then switch between them from the unit or its wired remote. It supports video up to 4K at 60Hz and shares USB peripherals across connected computers. For a multi-PC desk, it offers a more centralized setup than plugging peripherals into each computer separately.

How it fits

This switch is designed for a workstation with as many as four computers and one monitor. Its inputs include two HDMI ports, one DisplayPort port, and one Thunderbolt port, making it useful when a desk combines desktops, gaming laptops, or ultrabooks with different video connections. The monitor is shared between the connected computers, while the keyboard, mouse, and other USB devices can move with the active computer.

That setup suits an office where work moves between computers, a home desk with a laptop and desktop, or a multi-computer workspace that also uses a webcam or USB drive. A separate set of peripherals for every computer is another approach, this KVM is for people who prefer to operate from one shared keyboard and mouse instead. It is not compatible with ultra-wide or curved monitors, so choose a standard monitor format for this setup.

Benefits

Switching is available through the front-panel buttons or the wired remote controller. Use the front controls when the KVM is within reach, or place the remote where it is convenient to change computers from your usual seat. LED indicators show which computer is active, giving you a quick visual reference before continuing work.

The switch supports up to 3840 × 2160 at 60Hz and is backward compatible with 4K at 30Hz, 1080p, and other mainstream resolutions. Its adaptive EDID chip is designed to maintain a stable picture as you move between connected computers. For everyday tasks such as reviewing documents, editing images, or viewing media, the shared display stays at the center of the setup.

Four USB 3.0 ports and a separate USB-C port support sharing peripherals such as a keyboard, mouse, USB drive, or webcam. The design is plug-and-play and driver-free, with support for Windows and macOS. Keyboard hotkey switching is not supported, use the physical buttons or the wired controller to change the active computer.
