The UGREEN CM217 (Model 50966) is a bi-directional HDMI switcher and splitter that allows you to manage multiple video sources or displays without the need for constant cable swapping. In its primary switcher mode, you can connect two HDMI input devices, such as a gaming console and a PC, to a single display and toggle between them using a manual push-button located on the top of the unit. Alternatively, it functions as a splitter where one HDMI source can be shared across two different displays, though only one monitor will display an image at a time. The device supports high-resolution output up to 4K at 60Hz, as well as 2K at 144Hz and 1080P at 120Hz, ensuring smooth visuals for gaming and high-definition media. It also includes compatibility for advanced features like HDR, 3D content, HDCP 2.2, and high-fidelity audio formats such as Dolby TrueHD and DTS-HD.
