CHAPTER 4: Operation

4.3.4LEVEL UP AND LEVEL DOWN

The Level button adjusts the color mapping to compensate for computer-to-computer differences. Just as colors look different on different monitors, there will always be some color differences between the monitor and the Projection Panel. If the color match between the monitor and the Projection Panel is not satisfactory, the level can be adjusted to change the mapping. It is important, however, to ensure that the Tint or Contrast is set correctly prior to adjusting the level.

Level Up or Level Down increases your flexibility by allowing you to choose which tones of color/greyscale will be projected.

Pressing Level Up increases the limits of the range of tone which will be depicted by that color. Pressing Level Down will cause a smaller band of tone to be depicted as a given color. There are 64 steps. The level controls operate only on analog video signals such as those from VGA, MCGA, or Macintosh II display systems.
