Example: if monitor vrr range is 40 - 60Hz and * flip at refresh_rate > 60Hz: Flip should happen at the flipline boundary & returned refresh rate would be 60Hz. * flip at refresh_rate == 50Hz: Flip should happen right away so returned refresh rate is 50Hz. * flip at refresh_rate < 40Hz: Flip should happen at the vmax so the returned refresh rate would be 40Hz.
