  room is at its brightest when setting this level.

  Select “1” in the AUTO BRIGHTNESS menu.  

  (Figure 1) 

  Then use the front buttons to move the cursor 

  up to the BRIGHTNESS setting. Choose the

The brightness of the LCD screen can be set to increase or decrease depending on the 

amount of ambient light 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.

The Auto Brightness function is set to OFF by default.
