When displaying computer patterns which repeat every other dot (tiling, vertical stripes, etc.), interference may
occur between the LCD pixels, causing flickering, vertical stripes, or contrast irregularities in portions of the screen.
Should this occur, use the ADJUSTMENT / buttons for HORIZONTAL (LEFT/RIGHT) and VERTICAL (UP/
DOWN) POSITION ADJUSTMENTS to adjust for the optimum picture.
