False. This has nothing to do with HDMI 2.1. Nvidia doesn't sell any graphics hard that have HDMI 2.1.

VRR is optional on HDMI 2.0

Why not just use Optical out for devices that will not use eARC, or, cannot make use of such audio to a beneficial level? I don't know about which tv's you got, but I would be surprised if they didn't have optical out, I guess is my point.

You can’t carry a Dolby Atmos signal over optical, it has to be HDMI

Yup. You can't even do lossless DTS-HD or Dolby TrueHD, let alone Atmos over TOSLINK. Obviously someone was posting without sufficient knowledge of the subject matter. As for nVidia not supporting HDMI 2.1, you can do it with everything back to Pascal cards via a DisplayPort 1.4 to HDMI 2.1 active adapter. Finding a decent one that actually does it is sketchy at this point since nothing actually supports 2.1 yet to test on, but it's part of the spec.

This is being implemented natively, not via adapter. They are jerry rigging the optional spec channels to support true HDMI consortium VRR.

Is there ANY adapter of this type currently on sale?

Finally! The first TV's with VRR and Dolby Vision! My Xbox has been waiting for this day for some time!

Weak tv series. I want better PPI. I do not want to see the pixels. I want to see the image! 1080p is for up to 24 inches, 2k is from 24 to 32 inches, and finally 4k should be between 32 to 50" max. If those were 8k, they would be instabuy for me. Those gaming specs aren't gonna sell me. 😡 🙄

Fully aware of this - but didn't think you were actually using anything that gave that signal out, so figured it didn't really matter. What are you using that gives out such a signal?

I have a 4K Blu Ray player (LG UBK80) and a LG soundbar (SL10YG) that support Dolby Atmos and DTS:X. Also have an Xbox One X

Okay, but...don't you need content that is actually of that type to produce/attain the benefits of it? It was kinda my point. Just use the optical because you are not really going to use the DA/DTS much if at all, so, it's not a problem?

If you believe sellers on Amazon, yes. 😛 Like I said, since there are almost no 2.1 capable displays at this point (I don't think there are any yet, actually), there is no way to know if they actually work. If they are following spec, they should, but you have to take everything sold on Amazon from a China-based seller with a lot of skepticism.

I play movies all the time, and pretty much every Blu-Ray supports lossless DTS-HD or TrueHD, which optical isn't good enough to do - it can support the compressed versions, but not the bitstream. The majority of 4K movies have Atmos tracks in addition to those lossless ones. Even Netflix and Amazon support higher bitrates than TOSLINK can pass for their original content. You are missing the point of eARC, though. You can get all of those audio formats by just inserting a $200 receiver from two years ago between the source and TV. The point of eARC is to be able to use the apps built into the TV rather than an external player. High end TVs have features in their apps that streaming devices don't, such as Dolby Vision support for Netflix and Amazon (maybe Hulu, too, I don't use it). So right now you have to choose between the top video capabilities or the top audio capabilities, eARC will let you get both.

Sounds cool! Input lag, though, seems to be the real problem with using most TVs with a PC (assuming that's what the g-sync is about). Even standard 60hz monitors are (had been?) much better than any TV I've used, even my latest TV, which is highly rated for gaming. Has that changed?

Most mid-range and higher TVs since 2016 or so have a low lag mode (either PC mode or gaming mode) that reduces input lag to under 15ms, vs the around 100ms that they have when using a non-gaming mode. RTings actually tests this on every TV they review, so you can check them out to see what's good and what's not so good. https://www.rtings.com/tv/tests/inputs/input-lag FWIW, I have been using an LG 55" C7 (the "low end" OLED model from 2017, rated at around 22ms input lag) as a monitor for over a year, and input lag has not been an issue for me even in shooters. If I played more competitively I would probably be wishing I was still using my old Predator Z35, but for most games and people 16ms is fine.

I am aware of this, but, I question whether there is any difference noticeable, and, I question whether it is worth worrying about as the majority of content is not concerned.

It wouldn't be the first time when they introduce new features in software from a newer standard. They have done it before. The only thing you need new hardware for is higher bandwidth, new features can be done in drivers or firmware. So absolutely true, they will support official HDMI VRR, not any pre-standard FreeSync variant that other screens may support.
