From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Let's assume there are some crazy displays where the high end of the VRR range ends up being lower than the refresh rate as determined by the actual timings. In that case when we toggle VRR on/off we would step outside the VRR range when toggling VRR on/off. Let's just make sure that never happens by not using VRR in such cases. If the user really wants VRR they should then select the timings to land within the VRR range.
