What does an AWG rating have to do with a HDMI cable?

Problem shooting my Apple TV 4K HDR. Can get 4K resolution but not HDR. Think all my other components are 4K/ HDR compatible.

Thank you.

    I think the HDMI cable needs to be version 2.0 to be compatible with HDR. And soon it will need to be version 2.1 (48 kb/sec.) to be compatible with Dynamic HDR. (Yes, I know. That sounds redundant.) And also 8K, which will be here sooner than you might think. Not to mention some of the high color gamut stuff. I'll let them sort all of that out before I start upgrading. :#

    And back to your original question, I don't think wire gauge comes into play just yet, but it will with 2.1.

    For HDMI cables they're usually 23-26 gauge wire for the conductors. Longer run cables are usually 23awg. Not all HDR is created equal amongst the brands. Something might not be talking the same language.

    The difference between 1.4 and 2.0 was hardware/firmware/software related, not cable related. The requirements for cables didn't change a bit. If you are having an issue with components that are not talking to each other properly and are supposedly capable of the latest and greatest offerings, then you are most likely a firmware update away from the two pieces working together fully.

    With that said, all things being equal in construction of the cables, I always go with the larger gauge cabling if flexibility of said cable is good.
