6.4.1 Adjusting the position, phase, and frequency
Analog video sources deliver signals that have to be converted into digital signals by the
LCD monitor using a video digitizer. Depending on the 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 monitor.
Comparison of position, frequency and phase
Note
The auto function for adjusting brightness and contrast is only available for analog signals.
The picture quality for digital video signals is already optimized, and adjustment is not re-
quired.
If the image geometry is not shown correctly, proceed as follows:
1. Use the SMPTE test pattern for the display.
2. Select the function "Analog Settings" in the "Geometry" menu.
3. In the "Geometry > Analog Settings" menu, select the function "Auto Position/Frequency/
Phase".
4. Start the autofunction with "Yes".
ð The monitor recognizes the standard used, and has preprogrammed set-up values for
each standard. However, depending on the graphics card used, fine adjustment may still
be required for the selected standard.
Fine adjustment of the monitor
During fine adjustment, the monitor is adjusted manually to the respective video source. The
fine adjustment encompasses settings for position, frequency, phase and image sharpness.
•
In the menu "Geometry > Analog Settings" of the OSD, set the position, frequency and
phase.
Note: By adjusting the image position, you ensure the full picture is displayed on the ac-
tive area of the monitor, down to the last pixel. If the horizontal position is shifted 1 pixel
too far to the right for example, a 1 pixel-wide edge on the right side of the picture is lost,
and a 1 pixel-wide black column is displayed on the left side.
•
Set the sharpness in the "Geometry" menu.
6.4.2 Adapting brightness and contrast
The brightness and contrast must be adjusted for the respective graphics card in the system
on site due to different output levels.
Note
The exact brightness and contrast settings are only possible with a photometer.
Perform the following steps unless a specific procedure is specified for the system.
