Q: I plan to buy an Nvidia RTX 3080 because of its HDMI 2.1 support—it’ll pair nicely with my LG C9 TV. I’ve researched cables, but information about actual HDMI 2.1 48Gbps compliant ones is all over the place. Do you have a recommendation for what to buy?
If you’re able to shop at a physical store, the easiest solution is to look for an Ultra High Speed HDMI cable when they become available in Q4 2020. Cables with that specific label must support all HDMI 2.1 features, including bandwidth up to 48Gbps—and can only earn the designation after undergoing mandatory certification from the HDMI Licensing Administrator group, which oversees the HDMI specification. Genuine products will have an official QR code and hologram on the packaging that you can scan in a mobile app for verification.
