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.
NOTCH FILTER
Turn on the Notch Filter when viewing a television 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.
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 colortubes. 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.
