pixel to be blanked, etc.
Right
Adjusts the right-hand edge of blanking.
A value equal to the number of active
pixels per line in the current input
standard indicates that no input pixels
that are normally visible should be
blanked. Subtracting 1 from this causes
the last input pixel to be blanked, etc.

setting of 1 indicates that no input lines
that are normally visible should be
blanked, 2 causes the first input line to
be blanked, etc.
