Review: Cumple con la función de pasar señal 4K 120hz hasta 12 bit color Full Gamma. Pero se pierde compatibilidad con VRR (Gsync / Freesync) Si tienes una RTX 20XX y no quieres estar limitado al HDMI 2.0 este adaptador es la opción, pero considera que no es compatible con VRR.

## Questions & Answers

**Q: Is this adapter bidirectional?**
A: No. It only coverts video from USB-C with DP Alt Mode or Thunderbolt 3/4/5 ports (host) to HDMI displays. It does not support HDMI sources like PS5 or Xbox to USB-C devices.

**Q: Does this adapter work with macOS?**
A: Yes, but macOS systems are limited to 4K@60Hz output over USB-C/Thunderbolt, regardless of the display’s capabilities.

**Q: Why do I experience flickering or no signal?**
A: Use a short certified HDMI 2.1 cable and confirm HDMI 2.1 mode is enabled on your display. Try lowering resolution or refresh rate. Search “Cable Matters 48Gbps Adapter Troubleshooting” for further instructions.

**Q: Why am I not getting 8K or 4K 240Hz?**
A: It require a GPU that supports 8K or 4K240Hz over USB-C (RTX 20/30/40, RX 6000/7000, Intel 11th/12th Gen or newer), an HDMI 2.1 display, and a certified HDMI 2.1 cable. Enable HDMI 2.1 mode on your display and drivers are up to date.

### ⭐⭐⭐⭐⭐ Review
*by M***S on 10 December 2024*

I have the AMD RX6800 XT graphics card in my computer, it has one HDMI output, two DisplayPort and one USB-C. The HDMI was already taken by another monitor I use, so I ended up opting for USB-C -> HDMI to be able to share screen to my TV. Cheap adapters kept limiting my connection. One gave me only 24Hz, very "laggy" picture. Another would top out at 30. A third wouldn't even let me reach 4k. Then I decided to go for the recognized Cable Matters, and just out of the box I can turn up all settings without any issues. Thanks for a reliable device! Extra bonus star for the fact that firmware updates are available even after buying the product. That's was beyond expected. 6/5!
