Period
This divides one day (24 hours) to two periods. You can set
different hue, brightness, and contrast for different periods.
Hue
This is to adjust monitor video brightness and darkness level.
The default value is 50.
The bigger the value is, the large the contrast between the
bright and dark section is and vice versa.
Brightness
This is to adjust the monitor window brightness. The default
value is 50.
The larger the number is, the brighter the video is. When you
input the value here, the bright section and the dark section of
the video will be adjusted accordingly. You can use this function
when the whole video is too dark or too bright. Please note the
video may become hazy if the value is too high. The value
ranges from 0 to 100. The recommended value ranges from 40
to 60.
Contrast
This is to adjust the monitor window contrast. The value ranges
from 0 to 100. The default value is 50.
The larger the number is, the higher the contrast is. You can
use this function when the whole video brightness is OK but
the contrast is not correct. Please note the video may become
hazy if the value is too low. If this value is too high, the dark
section may lack brightness while the bright section may over
exposure. The recommended value ranges from 40 to 60.
