Image controls - sharpness and brightness

The X2 Multi Screen modules incorporate special controls to compensate for losses incurred within long cable links. Using these controls you can adjust the picture sharpness and brightness to improve your remote picture quality. The

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.

controls allow you to either affect all of the video channels collectively, or where losses are inconsistent, select and adjust channels individually.

The need for image control adjustment is best discovered when viewing high contrast images with vertical edges, such as black lines on a white background. When doing so, if you notice that the screen image is ‘fuzzy’ or ‘dark’ then the image controls may be able to solve this condition.

Note: If the high contrast images exhibit shadows with separate colours, then there may be a skew problem which requires a different image adjustment - see the ‘Skew adjustment’ section for details.

•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.

•A BLACK shadow on the right of the character indicates UNDER compensation.

•A WHITE shadow on the right of the character indicates OVER compensation.
