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 which use PAL equipment or 
Japanese NTSC standard, the grayscale is measured 
from 0 IRE (black) to 100 IRE (white). We suggest that 
you check the input source if it is with 0 IRE or 7.5 IRE, 
then select accordingly.
