VRR is short for variable refresh rate, a feature added with HDMI 2.1.It's useful for video games, as it means they do not have to deliver frames perfectly in sync with the display's fixed refresh rate in order to present a smooth experience. I mention G-Sync/Freesync certification, because it is all too common for VRR-capable displays to only do the bare-minimum to meet the HDMI 2.1 spec otherwise.

Dolby Vision and HDR10+ are newer premium HDR formats.

I'll talk this over with our firmware designer. I believe most of the things you're asking for come standard as part of the HDMI2.1 spec and the latest spec seems to be HDMI2.1a. As of right now, we are only compliant up to HDMI2.0 due to the nature of our commercial market. They prefer reliability over cutting edge. However, I don't see updating to the new spec as a major issue. High-end FPGAs have really come down in price and have made it much easier to accomplish such tasks due to their high throughput capabilities.

For gaming consumers you really need 2.1 I believe.

That's great to hear.

Don't just do the bare minimum VRR support to be HDMI 2.1 compliant though. The spec only requires a very narrow VRR window. Lots of cheaper devices make this window 48 to 60 hz, even when the display itself supports fixed refresh rates up to 120 hz. VRR should work anywhere from 30 all the way up to the maximum refresh rate supported by the TV. That is why I mentioned the G-Sync/Freesync Premium certifications.
