AI (ARTIFICIAL INTELLIGENCE)
When the AI function is on, the TV's internal computer will perform the following:

1. Automatically monitor and adjust contrast depending on room lighting (sensor is
located on the front panel), to produce a more natural picture.
2. Automatically monitor and adjust color levels and maintain natural flesh tones.
3. Automatically compensate for weak or strong TV signals to produce a clear picture.
(The SHARPNESS function is automatically adjusted.)

Turn the AI function off to control other PREFERENCE SETTINGS.

AUTOCOLOR
The AUTOCOLOR function automatically monitors and adjusts the color to maintain
constant color levels even after a program or channel changes. It also maintains

NOISE REDUCER

degrading picture quality.

CONVERGENCE ADJUST

Your Projection TV has three color projection tubes: one for red, one for green, one for
blue. When mixed together in the proper proportion, the output of these three color
tubes can produce any color. To produce these colors, however, the beams must be
precisely aligned over each other so that the colors can be mixed. The process of
aligned these picture beams is called "convergence".

Over a period of time, the picture tubes can drift out of alignment due to normal bumps
