To keep the LCD brightness within a specific range, not the 0~100% wide range, adjust
the minimum and maximum value of the LCD backlight. For example, set the Light Min. to
30 and the Light Max. to 70. Then, the adjustable LCD brightness range is among 30% to
70%. By doing this, the LCD brightness does not become too bright or too dark if the
ambient light reaches the default maximum or minimum value.
LUX Max. and LUX Min.
The SRM series is an ideal product for outdoor display. However, if the SRM series is
installed in an environment with stable and low lux lighting, the LCD monitor cannot detect
the default maximum lux (5200 lux) and make the LCD brightness reach to the maximum.
To set the LCD brightness to the maximum value, the user can adjust the default
maximum lux value.
For example, in a low lux office desk lighting environment, the default lux maximum value
may be adjusted from 52 (5200 lux) to 4 (400 lux). Once the setting is changed, the
monitor detects the ambient light and increases the LCD brightness to the maximum
(Figure 6-9). In this case, the LCD brightness increases in a low lux environment by
decreasing the maximum LUX value while keeping other settings in default (Figure 6-10).
