2.6.1 Benefits
With Ambilight, you enjoy a more relaxed viewing
experience and improved perceived picture quality.
Dim the lighting conditions in the room and position the
TV up to 25cm away from the wall for the best Ambilight
effect. To prevent poor infrared remote control reception,
position your devices out of sight of Ambilight.
