consumption by 30%.

• Black Level
Sets the picture grayscale to 0 IRE or 7.5 IRE.
The grayscale video signal is measured in IRE units. In some
areas which use NTSC TV standard, the grayscale is measured
from 7.5 IRE (black) to 100 IRE (white); however, in other areas
where PAL equipment or Japanese NTSC standards are used,
the grayscale is measured from 0 IRE (black) to 100 IRE (white).
We suggest you to check if the input source is with 0 IRE or with
7.5 IRE, and then make your selection accordingly.
