Triple Display Connectivity: Connect up to three external monitors using two HDMI outputs and one DisplayPort. Independent extended screens require a compatible Windows laptop with MST and sufficient GPU/display bandwidth. On macOS, the connected external monitors show the same content, not three independent desktops.
Up to 4K at 60Hz per Video Output: Each HDMI output and the DisplayPort support up to 4K at 60Hz. Actual resolution and refresh rate depend on the host's video bandwidth, the number of connected displays, cables and monitors. These individual port ratings do not guarantee three simultaneous 4K 60Hz displays on every laptop.
Four High-Speed USB Data Ports: Two USB-C and two USB-A USB 3.2 Gen 2 data ports support transfer rates up to 10Gbps. The USB-C data ports do not support video output or charging.
100W PD Input, Up to 85W Laptop Charging: The dedicated USB-C PD input accepts up to 100W, with up to 85W passed through to a compatible laptop. Maximum charging requires a suitable 100W USB-C PD charger and cable; actual charging depends on the laptop and power supply.
Check Your Laptop's USB-C Port: HDMI and DisplayPort output require a host USB-C port that supports DisplayPort Alt Mode. A USB-C connector alone does not confirm video compatibility. Laptop charging also requires USB-C Power Delivery support.
The UGREEN CM639 35625 8-in-1 USB-C Docking Station adds two HDMI outputs, one DisplayPort, four USB data ports and a USB-C PD input to a compatible laptop. It supports independent multi-monitor workspaces on compatible Windows MST systems. On macOS, the external displays mirror each other, while the laptop screen can display a separate desktop. This model does not include Ethernet, a memory-card reader or a dedicated audio port.
