double-click the monpanel icon.

The default color mode on Presenter 1280 is 18-bit. In this mode, some
smooth shaded images appear banded. If you wish to decrease this banding,
and if you have 24-bit graphics, you can switch to 24-bit mode. In that mode,
however, some colors may flicker. So you may want to switch back and forth,
depending on the types of images you are viewing.
When you choose 24-bit mode, the display creates additional colors by
averaging the true colors it displays in 18-bit mode. The result is a palette of
15,990,784 colors, not quite the 16,777,216 in true 24-bit).
To switch between 18-bit and 24-bit mode, use the Monitor Panel. Follow
