slide bar that you can use to adjust the delay by up to 250ms.
●Dolby Digital Comp Try Now
Set Dolby Digital compression mode.
●Auto Volume Try Now
When you change channels, video sources, or content, Auto Volume automatically adjusts the
TV's volume level so that the volume level remains the same for all sources. For example, if you
switch from a streaming video application to a Blu-ray player or a favorite TV channel, Auto
Volume can modify the volume up to 12db to equalize the sound.
The Auto Volume function has two settings: Normal and Night. Normal applies a normal level
of volume adjustment. Night applies a slightly lower volume level and is ideal for late-night TV
viewing. If you want to use the volume control of a connected source device to control the sound,
deactivate the Auto Volume function. When you use the Auto Volume function with a source
device, the device's volume control may not function properly.
