CHAPTER 4: Operation
Fig. 4-17. Rear Projection.
Selecting ON for the Text Mode
locks VGA text to solid pixels (no
shimmering). CGA graphics,
however, may be compressed. Unless
you regularly project CGA graphics
with the Projection Panel, text mode
should be set to ON.
Text Mode works only when text
is present. For example, this mode
works in VGA text but not in VGA
graphics.
You are now ready to begin a
presentation.
Now that the Projection Panel is
properly connected and you have
adjusted the image on the screen,
you are ready to begin projecting
your computer data and graphics.
The projected images will be live
from your computer and change as
you change the computer data.

Text Slice allows you to adjust VGA
text characters to look their best.
The Projection Panel discards one
of seven pixels to adjust characters.
Text Slice allows you to choose
which of the seven pixels you want
the Projection Panel to discard. Text
Slice is ON for only 720 text mode
(VGA text). Text Slice has no effect
on characters when Text Mode is
OFF. Adjust the Text Slice until your
characters are solid and fully
formed.

The Projection Panel screen area is
640 pixels wide. Text that extends
beyond 640 pixels may be either
compressed or truncated. When text
(or graphics) is compressed, it is
tightly spaced to fit the display
screen. Truncated text (or graphics)
is not respaced to fit the display;
rather, anything beyond the right
edge of the screen display is not
shown.
