Unfortunately I don’t think the auto refresh rate switching works for any s905x box (not inside Android apps). Maybe in Kodi? But no it isn’t like the MiniX boxes.
As far as I remember, there are NO s905x boxes that can do it. However, I see you are interested in the VIM2, but I am unsure if any s912 box makers have or plan to add that feature. It is the ONE feature in my opinion, would be a deal sealer for a lot of folks to get on board.
