Monitor adjustment - Force Mode

6.4.6.1 Introduction
Various factory-set timings are saved in the monitor. As soon as a video signal is connect‐
ed, 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 ranges. Such signals frequently occur with older medical equipment. A timing of
this sort can be set using the Force Mode functions.
In many cases, a signal outside the standard ranges is displayed correctly without having to
use Force Mode. This is possible because a large number of known timings are saved in the
monitor.
Force Mode timings can be saved in the custom settings. Thus, up to five additional Force
Mode timings are available. See Service level 2 functions
Only one timing can be saved in Force Mose itself.

NOTICE
Force Mode is an engineering tool
Force Mode is only used to determine exotic and unknown timings.
An unknown timing can be used in the monitor with these data.

Scanning in the interlaced and non-interlaced procedures
There are two different scanning systems. They differ in the technology used to display the
image on the screen TV signals and monitors which are compatible with them are normally
set to the interlaced procedure; computer signals and monitors compatible with them are
normally set to the non-interlaced procedure. These two formats are not compatible; one of
them must first be converted before the signals can be processed together.
In the case of interlaced scanning, each image is divided into two separate fields. An image
therefore comprises two fields. An interlaced image is output on the screen in two scans.
The horizontal lines of the first field are scanned first, and then, again starting at the top of
the image, the horizontal lines of the second field are scanned between the first set of lines.
Field 1 consists of the lines 1 to 262 1/2, and field 2 of the lines 262 1/2 to 525. Only a few
lines are displayed at the top and bottom of each field.
