The maximum current is 1A. Connection or disconnection of a unit may only be
carried out by servicing personnel or those trained by them.
6. Adjustments
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 DVI-A 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 DSC191
3-D using an OSD menu.
To optimize the display settings for the installed graphic board, and to ensure all
gray levels are distinguishable, we recommend to adjust the brightness and
contrast levels for and only for analog inputs. Note that the calibration (in the
Look Up Table) is not changed by these adjustments (All the monitors are and
remain factory calibrated):
Using a 100% black picture and an appropriate measurement device (a spot
