    <!-- 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.

         For example, fixed refresh rate if

             display brightness >= disp0 && ambient brightness >= amb0

             || display brightness >= disp1 && ambient brightness >= amb1 -->
