RGB Adjustment Controls
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 ß/© buttons for HORIZONTAL (LEFT/RIGHT) and VERTICAL
(UP/DOWN) position adjustments to adjust for the optimum picture.

and “H-POS”)

2) with the INPUT SELECT button and press the MENU
button.
With the MENU screen displayed, press the ADJUSTMENT ƒ/∂ buttons
to select “RGB 1 INPUT ADJ.” Then press the ENTER button to display the
“RGB 1 INPUT ADJ.” screen.
