Good point. I’ll just argue about HDR and high frame rates being desirable features :) I don’t even know what VRR is.

VRR is Variable refresh rates, so if there is nothing going on in the content, they can bring the refresh rate down and save processing, thermal issues and energy. If there is a lot going on(say a game), they can ramp the refresh rate back up super high.

There are a few different "standards" around VRR, not every device supports all of them.
