Until 8K is a standard HDMI 2.1 is not yet needed.
Sorry but I don't agree with that assessment. I think it's wrong to imply that HDMI2.1 can be dismissed because it's all about 8K and far in the future. Only a few months ago, people were asking (unrealistically) if the 2017 Denons would have it.
HDMI 2.1 will offer, among other things, support for HDR10Plus aka Dynamic metadata for HDR10. Just as people were hopping around wanting the updates for "pass-though" (short-hand for decode-repackage-transmit) of HLG, and dolby vision, so equally, the same applies for HDR10Plus
. If you want to be future-proof that means wanting, no demanding, support for all
HDR formats from the manufacturers, and rejecting
what they want (a "format war" - see https://www.avsforum.com/forum/465-hi...-displays.html
). If there isn't the same fuss about pass-through for HDR10Plus as there was for HLG and dolby vision, we've already allowed them to stage a "format war"
HDMI 2.1 will also offer eARC which should matter to any audiophile (ie everyone on this thread) who wants the HD audio formats to be supported rather than 1990's lossy 5.1-max audio over ARC at present (patchy support for DD+ over ARC excepted).
I'd also expect HDMI2.1 to offer proper standardised support for some "missing" 4K picture modes not officially supported by HDMI2.0 which will be very important for 4K Blu-Ray player owners who currently have to ask their player to up-sample to a different mode just to send the picture down the cable. (4K50/60 10-bit 4:2:2, 4K24 10-bit 4:2:2, 4K24 4:2:0). The last of those is the 4K Blu-Ray disc format so people will have a keen interest in sending the unadulterated picture down the cable to allow the TV to do as much or as little processing as the user wants. Presently, they are forced into allowing the player to unpack the chroma sub-sampling.
If some or all of those features are available as firmware upgrade on current/new hardware all the better. They are all features of HDMI2.1.
