Video compensation (sharpness and brightness)
Using the in-built X100 controls you can adjust the picture sharpness and
brightness to improve the remote picture quality.
Video compensation is best carried out 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 not
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
(provided only by the Adder X100AS receiver) - see the
section for details.
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.
• A BLACk shadow on the right of the character
indicates UNdER compensation.
• A WHITE shadow on the right of the character
indicates OVER compensation.
Note: The Word processor method is accurate
and quick. However, for the very finest video
compensation, use the latest Adder "skew" test
pattern program which shows both the skew
pattern and a section of mixed size Hs (black on
white and white on black).
If the image controls cannot provide a crisp image
If, after adjusting the image controls, one or more screen images remain
fuzzy or have coloured shadows you may need to use the Skew adjustment
feature. Please see

The three keyboard indicators ('Num Lock', 'Caps

level of the sharpness adjustment currently applied:
the slower the rate, the lower the level of sharpness
being applied.
