Using the Auto Brightness function
The brightness of the LCD screen can be set to increase or decrease depending on the amount of ambient lighting within the
room. If the room is bright, the monitor becomes correspondingly bright. If the room is dim, then the monitor will dim accordingly.
The purpose of this function is to make the viewing experience more comfortable to the eye in a variety of lighting conditions.
SETUP
Use the following procedures to select the brightness range the monitor will use when the [AUTO BRIGHTNESS] function is
activated.
1. Set a level for the bright room condition. This is the maximum brightness level the monitor will rise to when the ambient
lighting level is highest. Configure this setting when the room is at its brightest.
Select [ON] in the [AUTO BRIGHTNESS] menu ( Figure 1). Then use the front Keys to move the cursor up to the
[BRIGHTNESS] setting. Choose the desired brightness level ( Figure 2).

2. Set a level for the dark room condition. This is the minimum brightness level the monitor will lower to when the ambient
lighting level is low. Make sure the room is at its darkest when setting this level.
Then use the front Keys to move the cursor up to the [BRIGHTNESS] setting. Choose the desired brightness level ( Figure 3).
