The remote module has a video adjustment to control picture sharpness on the display screen.

To adjust video sharpness:

1.On the computer, display a suitable high contrast image, ideally with one or more black vertical lines on a white background (for example, a capital “H” at 72 points in a word processor—see Figure 4-1).

2.Insert a small screwdriver into the adjustment screw on the side of the remote module.

3.Turn the screw fully clockwise—you should see a bright white shadow to the right of your high contrast image

4.Turn the screw counter-clockwise until the white shadow disappears and the edges of your image become sharp.
