		<!-- The display uses different gamma curves for different refresh rates. It's hard for panel
		vendor to tune the curves to have exact same brightness for different refresh rate. So
		flicker could be observed at switch time. The issue can be observed on the screen with
		even full white content at the high brightness. To prevent flickering, we support fixed
		refresh rates if the display and ambient brightness are equal to or above the provided
		thresholds. You can define multiple threshold levels as higher brightness environments
		may have lower display brightness requirements for the flickering is visible. And the
		high brightness environment could have higher threshold.
