Press the AUTO ADJ. button to fine-tune the computer image or to remove any vertical banding that might appear and
to reduce video noise, dot interference or cross talk (this is evident when part of your image appears to be shimmer-
ing). This function adjusts the clock frequencies that eliminate the horizontal banding in the image. This function also
adjusts the clock phase to reduce video noise, dot interference or cross talk. (This is evident when part of your image
appears to be shimmering.)
This adjustment may be necessary when you connect your computer for the first time.
NOTE:
Some signals may not be displayed correctly or take time.
The Auto Adjust function does not work for component and video signal.
If the Auto Adjust operation cannot optimize the RGB signal, try to adjust Horizontal/Vertical Position Clock and Phase
manually. See pages 45 and 46.
