-PICTURE- FUNCTIONS
Use the CURSOR
Press ENTER to turn function on or off.
When the AI function is on, the TV internal computer will perform the following:
Automatically monitor and adjust contrast depending on room lighting (sensor is
located in the front panel), to produce a more natural picture.
Automatically monitor and adjust color levels and maintain natural flesh tones.
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 PICTURE 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
natural flesh tones while preserving fidelity of background colors. For best picture
performance leave the AUTOCOLOR function on.

• NOTCH FILTER

Turn on the NOTCH FILTER when viewing a television program or a program from one
of the regular video inputs to improve the picture appearance, especially around the
outline of buildings, signs, letters, etc.
Turn off the NOTCH FILTER when viewing a program from the S-Video input to get the
maximum sharpness and clarity out of the picture.

• NOISE REDUCER

The NOISE REDUCER automatically reduces conspicuous noise in the picture without
degrading picture quality.

• CONVERGENCE

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
aligning these picture beams is called "convergence".
Over a period of time, the picture tubes can drift out of alignment due to normal bumps
and vibrations or moving the TV. If you move your TV, or if, after a time, you notice
color rings or halos around objects in the picture, you may want to converge (align) the
colors.
