At a shared workstation, a graphic designer toggles between a desktop PC and a laptop without reaching for cables. The UGREEN CM664 KVM switch keeps one monitor, keyboard, and mouse ready for both machines, so switching takes a single press or hotkey.

Why choose it

Built for efficient workflows, the CM664 eliminates cable clutter and the need for extra monitors. Its aluminium shell dissipates heat effectively, while EDID emulation ensures monitors and USB devices stay responsive even when they are not the active source. The USB-C power input accepts a standard 5V/2A adapter, making setup straightforward at any desk. The built-in USB hub adds three Type-A ports, so you can keep a printer, flash drive, or headset dongle permanently connected and available on both computers.

Good to know

The CM664 supports HDMI 2.0 and HDCP 2.2, so 4K content from streaming services or Blu-ray players displays without issues. Hotkey switching works with the connected keyboard, and the LED indicator shows which computer is active. No drivers are needed—just connect the included USB and HDMI cables, plug in the power adapter, and start working.
