- The range of listed resolution and refresh-rate options may suit high-refresh gaming displays when the source and display support them.

## Before you buy

- The listing is inconsistent about product type and generation, calling it an adapter or cable and variously describing Thunderbolt 3/4/5, Thunderbolt 4/5 or USB-C DP Alt Mode. It also lists several maximum modes, including 16K@60Hz with DSC, without confirming which source and display combinations achieve them. Check device and monitor support, including DSC, before relying on a particular resolution, refresh rate, MST or audio mode. DisplayPort is not Mini DisplayPort or HDMI.

## A good fit for

- People connecting a USB-C or Thunderbolt laptop, tablet, smartphone or gaming handheld to a DisplayPort monitor or TV.
- Buyers seeking a high-refresh external display connection, provided their source and display support the chosen mode.

## Less suited to

- Anyone needing bidirectional conversion or a DisplayPort-to-USB-C connection.
- Displays or sources that lack the appropriate USB-C DP Alt Mode or Thunderbolt support, or the required DisplayPort connector.

## Customer feedback

The supplied evidence contains aggregate ratings but no customer-comment summary, so it cannot establish what buyers praised or criticised. The rating distribution skews strongly toward five-star ratings while also including lower ratings. Treat this as a broad signal rather than confirmation of compatibility or performance, which depend on the source, display and selected operating mode.

## Frequently asked questions

### Which way does the UGREEN CM654 carry the signal?
The listing specifies signal from a USB-C source to a DisplayPort monitor or TV only. It is not bidirectional.
### Does it guarantee 16K at 60Hz?
No. The listing claims 16K@60Hz with DSC, but actual modes depend on the source, display and DSC support. Confirm both devices support the mode you want.
### Can it connect to an HDMI or Mini DisplayPort display?
The listed output is DisplayPort. The listing cautions that DisplayPort differs from HDMI and Mini DisplayPort, so this adapter is not stated to connect directly to either.
### Does it support high-refresh gaming?
The listing claims FreeSync and G-Sync support and lists high-refresh modes. The source and display must also support the selected resolution and refresh rate.
