6.6 Adapting the monitor using Force Mode

Setting without a measuring instrument
Precise adjustment is only possible with a measuring instrument.
If there is no measuring instrument available for fine adjustment, proceed as follows:
• Use the SMPTE test pattern.
• Adjust the brightness so that image sections with 5 % and 0 % gray value still visibly
contrast.
• Adjust the contrast so that image sections with 95 % and 100 % gray value still visibly
contrast. To adapt the luminosity to the ambient lighting, adjust the backlight luminance.
CAUTION: the factory-set brightness is no longer maintained.
Note
To set the image parameters you can also use the adjustable LUT functions in the
LUT" menu [} 50].
Automatically setting the video source
In order to automatically adjust the video source, it must support communication via the Dis-
play Data Channel (DDC), and the devices must be connected correctly. When switched on,
the monitor's EDID data (Extended Display Identification Data) is read out, and the video
source can detect the monitor.
CAUTION
Installation and parameterization of the video source
Please refer to the video source manufacturer's manual for detailed information about in-
stallation and configuration of the video source.
6.6 Adapting the monitor using Force Mode
NOTICE
Force Mode is a service tool
Force Mode should only be used by service personnel to determine an unknown timing
and implement it in the monitor.

6.6.1 Introduction to Force Mode

Various factory-set timings are saved in the monitor. As soon as a video signal is con-
nected, an appropriate timing is sought. "Auto In Process" is displayed during this phase.
These timings are compatible with the standard video signals provided by current graphics
cards.
If no image or only an unclear image is displayed on the monitor, the signal is outside the
standard supported range. Such signals are common with older medical equipment. A tim-
ing of this sort can be set using the Force Mode function.
In many cases, a signal outside the standard range is displayed correctly without having to
use Force Mode. This is possible because a large number of known timings are saved in the
monitor.
