The maximum brightness is 7500 in this case.
When I keep stepping down the screen brightness, it will be down to 375 by 375 for each step.
When it stays in 375, I can not make it becomes 0 or 1.
The lowest brightness should be 1 in this case because the maximum brightness is greater than 99.
0 is not reachable so I used max(something, min) here. min is 1 in this case.
