Figures 9 is an example of second color display in the eighth row of the OSD.
Each of the small grid squares represents one pixel. Each column has two areas
for second color display. In this example, the second color is at Position 6. The
second color position for the first column has a value of 3 because the OSD is
offset from the left of the TV screen at a distance equal to 03h. Each column is
the size of one display character. Each Second color column is a half character
column. The screen position offset is added to Second color position. Because
the offset is 03h, the Second color postions begin with 3 = (3+0), 4 = (3+1), 5 =
(4+1), and so forth.

Column increment is 0.5. Offset is 03h. System software
requires that the offset be added to the increment for the
second color in the bar display. The bar position must be
defined before the second color is enabled.
