Is this adapter bidirectional?

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.

Why am I not getting 8K or 4K 240Hz?

It require a GPU with DisplayPort 1.4 + DSC via USB-C, a certified HDMI 2.1 cable, and a display with HDMI 2.1 input. Also ensure HDMI 2.1 mode is enabled on your display and drivers are up to date. VRR, G-Sync, and FreeSync are not supported.

Does this adapter work with macOS?

Yes, but macOS systems are limited to 4K@60Hz output over USB-C/Thunderbolt, regardless of the display’s capabilities.

Why do I experience flickering or no signal?

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.

The adapter gets warm — is that normal?

Yes. The aluminum enclosure helps dissipate heat from the chipset. Mild warmth during use is normal and ensures stable high-speed performance.
