How to use

Connect the UGREEN CM888 Uno to a compatible host device via its USB-C plug. To use video output, connect an HDMI cable from the hub’s HDMI port to an external monitor or TV; ensure the host device supports DisplayPort Alt Mode over USB-C. For charging, attach a USB-C PD charger to the hub’s USB-C power input if separate power is required; the hub supports pass-through charging up to 85W. Attach USB-A or USB-C peripherals to the corresponding ports for data transfer. Most operating systems will recognize the hub automatically; adjust display and power settings on the host device as needed.

Usage recommendations

Use a compatible USB-C PD charger rated to the desired wattage to achieve up to 85W charging. For stable 4K@60Hz video output, use high-quality HDMI cables and confirm the host device supports 4K output via USB-C. Avoid connecting high-power-draw peripherals that together exceed the host’s or the charger’s power capabilities to maintain reliable operation.
