To adjust video sharpness

1On the computer, display a suitable high contrast image (see right).

2Insert a small flat-bladed screwdriver into the SHARPNESS adjustment hole so that it engages with the slot in the rotary dial.

3Turn the rotary dial fully clockwise - you should see a bright white shadow to the right of your high contrast image:

4Turn the rotary dial anti- clockwise until the white shadow disappears and the edges of your image become sharp.

To display a suitable high contrast image The best way to clearly view the effect of sharpness and brightness adjustments is to display a high contrast image, with vertical edges, on the screen.

Open a word processor, type the capital letter ‘H’, or ‘M’ and increase the point size to 72 or higher. For best results, the background should be white and the character should be black.
