Optimize scanning frequency
The correct signal frequency now has to be set with "Total horizontal lines".
1. To set "Total horizontal lines" correctly, open a test pattern with a clearly defined border
(e.g., SMPTE image).
2. Correct the signal frequency so that no interference is present in the picture. If the dis-
tance between interferences becomes larger, and these therefore also become fewer,
you are changing the values in the correct direction.
Optimize geometry/resolution
The active resolution range is defined by the values of the "Horizontal Resolution" and "Ver-
tical Resolution" input fields. This range is displayed in the center of the monitor in black.
The inactive resolution range is the unused range between the active resolution and the
maximum resolution of the monitor. In Force Mode, this range is displayed gray (gray scale
monitors) or blue (color monitors).
SMPTE test pattern
Inactive resolution area
Active resolution area
To adapt the active resolution range to the actual video signal resolution, perform the follow-
ing steps:
1. Open a test pattern with a clearly defined border (e.g., SMPTE image).
2. In the "Force Mode" menu, use the "Horizontal blank pixel" input field to shift the left
edge of the SMPTE image pixel-exact to the left inside edge of the gray/blue area.
3. Correct the values in the "Horizontal Resolution" input field until the right internal border
of the gray/blue area is pixel-exact at the right edge of the SMPTE image.
