Hi, previous CAC-1085 had VRR support on its specification, but 1088 does not.
Does 1088 support VRR? It is said 1087 does not support VRR in other post at least.

FROM Twitter :
The Parade PS196 is supposed to support VRR but I don’t know if any adapters exist yet that use that chip.

Here’s something but I don’t know if you can get it or if it supports VRR.
