6.1 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 analog port. The digital input (DVI-D,DP) does not require a fine
adjustment since the display signal is always optimum.
RGB picture sources via VGA 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
