Computer Adjustments

When displaying computer patterns which repeat every 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, adjust "CLOCK", "PHASE", "H-POS" and "V-POS" for optimum computer image.
