Setting Black Level

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 that you check the input source to see if it is with 0 IRE or 7.5 IRE, then select 
accordingly.
