4.7.7TEXT SLICE

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.

4.7.8TEXT MODE

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.

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.
