Variable Refresh Rate With Asus VG246H connected over HDMI to an A750. When looking at the general tab under display in Arc Control the Variable Refresh Rate option is grayed out and the dropdown says "Not supported."
HDMI spec added limited support for Variable Refresh Rate (VRR) in its 2.0 version and full support for VRR in the 2.1 version. The Asus VG246H monitor uses the HDMI 1.4 version, which doesn't support VRR.
