Review: Best USB C to HDMI adapter for Dolby Atmos from PC - Perfect. The only adapter that works just as advertised. I bought this as it supports Atmos format content from PC without HDMI port and it is able to output Dolby Atmos audio without breaking a sweat. No heating issues, just plug and play. Even the driver update was not required, the one I received had the latest firmware preinstalled.
Review: Supports 4k@120Hz on M1 Pro - The model I received was 201388-A with VMM7100. You may need to update the firmaware but after that, it is just plug & play with M1 Mac and Supports 4k@120Hz on my LG C2.

## 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.

**Q: Why do I get only 4K@120Hz with Intel GPUs and Acer monitors?**
A: This is a known compatibility limitation with Intel GPU and Acer monitor setup when using this product. With AMD or NVIDIA GPUs, the same monitor can reach 4K@144Hz or higher.
