Review on 🔌 Cable Matters 8K DisplayPort 1.4 to HDMI Adapter: Unidirectional 8K Cable Adapter for RTX 3080/3090, RX 6800/6900 and More by Jared Allred

Worked for several minutes and decided not to work. When it worked I got 4k@120 but no HDR. The construction of the product was very weak, seemed to be of poor quality. I hear noises from inside with slight movement, which is not a good sign. Maybe I was unlucky and caught a defect. I will be returning the item and hope it worked so I can connect my 3090 to my Oled in the bedroom as my HDMI port is already in use. Please control your product quality better in future, thanks!
