Making picture corrections (Screen)
Set the picture size, brightness, etc. before you switch on moiré reduction.
i Only switch moiré reduction on if you can see light and dark stripes on your screen, or if the picture is dull and blurred.
In some cases, moiré reduction may cause the picture quality to deteriorate (reduced picture definition, slight flickering). To optimally restore the picture focus in the horizontal and vertical picture area, use the function Focus.

Setting or switching off moiré reduction (Clear Moiré)
If the picture you see on screen has light and dark stripes or appears dull and blurred, this may be due to what is known as the moiré effect. This effect usually has physical causes, being triggered by interference between the pixels in the matrix and the video signal. The intensity of the moiré effect is dependent on the screen resolution and horizontal frequency.
= Setting the horizontal moiré reduction intensity
= Setting the vertical moiré reduction intensity With a value of 0 the moiré reduction is switched off.
Adjusting the vertical linearity (Linearity)
Vertical linearity must be set when the screen display appears distorted at the top or bottom.
= Correcting compression distortion at the top or bottom of the display
Setting the picture definition (Focus)
This function enables you to improve focus – e. g. after the moiré reduction.
= Improving focus right and left range
= Improving focus up and down range
