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 in 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 natural flesh tones while preserving fidelity of background
colors. For best picture performance leave the AUTOCOLOR function on.
NOISE REDUCER
The NOISE REDUCER automatically reduces conspicuous noise in the
picture without degrading picture quality.
SUPER CONTR (SUPER CONTRAST)
Turn on SUPER CONTR to improve picture detail in areas of high
brightness.
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 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.
To simplify convergence, the following feature allows you to display a test
pattern of horizontal and vertical lines on the screen. Properly converged,
the lines appear white, which is actually a combination of the outputs of
the three color tubes. The output of the green tube is stationary. The
outputs of the red and blue tubes can be adjusted. When properly
aligned, the outputs of all three tubes should be directly over each other to
produce the white lines.
