2.13.7.1. Border Color
Table 2–59: Border color settings
Next to the character display area in which the charac-
ters are displayed there is an area which is surround-
ing the character display area. The visibility of this bor-
der area depends on the width and height of the
character display area. The user is free to define the
color vector of this border.
2.13.7.2. Full Screen Double Height
If double height is enabled for the full screen each line
of the OSD is repeated twice at the RGB output. As a
result, characters which are normally displayed in nor-
mal height, are now displayed in double height and
characters which are normally displayed in double
height are now displayed in quadruple height.
Row 0 and 24 are handled in a special way. If double
height is selected for the full screen these two rows
can be fixed to normal display (each line of these rows
is repeated only once).
In double height mode the user may want to start the
processing of the display at row 12 and not at row 0. To
decide this, three bits are used as a global attribute.
