Picture adjustment

This section describes the settings for operation of the flat panel display with a
video source. The most important settings are:
Adjusting the graphics memory of the video source
As with all monitors, the flat panel display also has certain limits, e.g. maximum
resolution and vertical frequency. The graphics adapter must be set when using the
flat panel display such that the limits are observed.
Fine adjustment of the flat panel display
Note
Fine adjustment of the flat panel display can only be carried out via the two analog
ports (15-pin Sub-D and DVI-I). The digital input (DVI-D) does not require a fine
adjustment since the signal display is always optimum.
RGB picture sources (via 15-pin Sub-D or DVI-I connector) supply analog signals
which are basically intended for conventional CRT monitors and which are
processed directly by them.
In contrast, the analog signals must be converted for a flat panel display into digital
signals by a video digitizer. Depending on the picture source, cable length and
video mode (e.g. VGA, SVGA, XGA) this conversion may cause certain deviations,
which cannot be corrected fully automatically by the flat panel display.
A manual fine adjustment is therefore necessary during which the flat panel display
(or, more precisely, the video digitizer) is matched to the respective video source.
The fine adjustment comprises e.g. setting the horizontal/vertical picture position
and the picture sharpness. This can be carried out for the color flat panel display
SCD 19101 D/DT using an OSD menu.

Optimum picture quality

In order to achieve an optimum picture quality, the color flat panel display
SCD 19101 D/DT should be operated with a graphics resolution of 1280 x 1024
pixels (settings for graphics card in the PC).
When adjusting the picture position and size, ensure that the picture appears
exactly on the active surface of the display and that it is not offset by even one
pixel. For example, if the horizontal position is offset by one step to the right, the
right-hand edge of the picture will disappear, and a black pixel column will appear
at the left-hand edge. And similarly for an offset to the left, top or bottom. If the
vertical lines are still slightly fuzzy, correct using the settings "Frequency" and
"Phase" (see Section 6.3.5 "OSD menu functions").
