You can click + or - buttons at the upper right side of the display to make a time shift between audio and video.

This can be useful when you have for instance an external audio system connected to the TV that needs extra few miliseconds to be fully synchronized with video. Yet another example can be a shift for certain movies where the audio is not fully synchronised with video. By default, audio is synchronised with video, i.e. ΔT is zero.

You can offset audio and video by up to 1000 msec, plus or minus, in 50 msec steps. Please note that you can experience audio dropouts during offsetting. Also note that you will not hear the offset immediately due to the lag.

The functionality is available only during the active session.
