Pros and cons

Pros

A claimed 4K at 60Hz mode suits presentations, general desktop use and video on a compatible display.
The listing names a broad range of laptops, tablets and phones, and says setup requires no special software.
Higher refresh-rate modes are listed for users prioritising smoother motion at lower resolutions.

Cons

This is a one-way connection from USB-C source to HDMI display, so it cannot send an HDMI source signal to a USB-C screen.

What to know before buying

Listing details to confirm

The listing gives conflicting lower-resolution refresh-rate claims: one section says 2K at 144Hz and 1080P at 240Hz, while another says 2K at 120Hz and 1920*1080 at 144Hz. Confirm the required mode and check that both source and display support it. The 4K at 60Hz and HDR claims are also dependent on compatible equipment, and the source must support DP Alt Mode. Customer feedback reports that the adapter can become warm after extended use.

Who is it for?

A good fit for

People connecting a DP Alt Mode-capable USB-C or Thunderbolt laptop, tablet or phone to an HDMI monitor, TV or projector.
Presenters who want to mirror or extend a compatible device to a larger display.
Users who want Samsung DeX on a supported Galaxy device and HDMI display.

Less suited to

Anyone needing a bidirectional adapter or an HDMI-to-USB-C connection.
Buyers whose USB-C device does not support video output through DP Alt Mode.

Customer feedback describes straightforward setup and positive experiences with functionality, build quality and compatibility, including use with Mac Studio and ProPresenter and with Mac and Windows displays. Some customers appreciate the price, while others dislike it, and reports mention warmth after extended use. These are customer perceptions rather than verified performance findings. The reported compatibility is relevant to the adapter’s intended USB-C-to-HDMI use, but the listing’s DP Alt Mode requirement still determines whether a particular device can output video.

Frequently asked questions

What does this adapter connect?

It sends a signal from a compatible USB-C source to an HDMI display. The listing says the connection is one-way, not HDMI source to USB-C display.

Will it output 4K at 60Hz?

UGREEN claims up to 4K at 60Hz. The source device and HDMI display must also support the required output.

Does every USB-C device work with it?

No. The listing specifies USB-C DP Alt Mode or Thunderbolt support. Check that the device can output video over its USB-C port.

Which higher refresh rates are supported?

The listing is inconsistent. It gives 2K at 144Hz and 1080P at 240Hz in one section, but 2K at 120Hz and 1920*1080 at 144Hz elsewhere. Confirm the mode you need.
