Scott says that the new HDMI standard will be pushing 4K and 8K video at over 5400 Gbps. Will HDMI ever be replaced? Scott says that if metadata doesn't survive going through an AV receiver, it could greatly affect the HDR10 dynamic range going to the TV. Your AVR needs to support HDMI 2.0A to do that, and few manufacturers will tell you that. Dolby has launched a program to educate people on which devices will support Dolby Vision.
Gary wonders if the new LG G6 series can enjoy HDR through Samsung's new Blu-ray player. It has to have HDMI 2.0a. But with DOlby Vision it only needs HDMI 2.0. Scott says that is correct. But what about the Vizio Reference series? It doesn't have HDMI 2.0a. Leo says that's because it's last year's model. So it can only receive Dolby Vision HDR, not HDR 10, which is what the Samsung Blu-ray player does. So Scott says to get the LG G6 TV. It does both. Will Vizio upgrade it with firmware? Scott says not likely. It's a hardware difference.
