UGREEN 15852 USB-C Dock with Dual HDMI

The UGREEN 15852 dock adds two HDMI outputs, three USB data ports and USB-C pass-through charging to a compatible USB-C device. Its listing claims dual 4K at 60Hz or 8K at 30Hz from HDMI 2, but Mac displays mirror rather than extending independently.

At a glance

Two HDMI outputs are listed for connecting external displays. The stated dual 4K@60Hz capability depends on the host's video output and bandwidth.
HDMI 2 is claimed to support a single display at 8K@30Hz. The listing says the host must support DP 1.4 and DSC for this mode.
USB-C PD pass-through is claimed up to 85W when paired with a 100W charger and cable, which are not included.
One USB-C data port and two USB-A data ports are described as supporting transfer speeds up to 5Gbps.
The listing warns that macOS shows mirrored images across two connected monitors rather than independent extended desktops.

Customer feedback is mixed on reliability, connectivity and value. Some report useful dual-HDMI operation, while others describe HDMI or USB issues, disappointment with value, or the dock stopping after several months. These reports matter if the dock will support regular multi-display work, where dependable ports are important. The aggregate ratings lean positive overall, but do not resolve those conflicting experiences or establish the cause of reported problems.

Negative themes

Frequently asked questions

Can it run two displays at 4K at 60Hz?

The listing claims dual 4K@60Hz, but says laptop bandwidth and video-output support matter. Confirm your host and cables can support the target resolution and refresh rate.

Can it show 8K?

The listing claims 8K@30Hz through HDMI 2 alone. It says the laptop needs DP 1.4 and DSC compression. Without DSC, it states the maximum is 4K@60Hz.

Will two monitors work as separate extended screens on a Mac?

No. The listing says macOS mirrors the image on one monitor when using this dock with two displays, rather than extending both independently.

Is a charger included for pass-through power?

No charger or cable is listed as included. The claimed 85W pass-through requires a 100W PD charger and cable.
