Yeah, the problem is that there is a well-set standard for VRR on a regular DP connection, there’s a so-so standard for VRR on HDMI, but there isn’t a good standard for communicating VRR through an internal connection. The market is at a standstill with not enough tablet vendors asking for VRR, and neither the SoC vendors or the panel vendors want to be the first one to build only half of the solution. Apple or Samsung could build a full solution on their own and jumpstart that market, but can’t be arsed.
