Description
Automatically calibrate A/D converter for
the applied video level
The video level range of the system is
checked, and the monitor set accordingly. This
results in optimum adjustment of the individual
RGB A/D converters to the video source.
The calibration results in a larger and more
flexible video level range (e.g., the full bright-
ness is also achieved at 700 mV if the video
level is limited at this value).
Note: A suitable test pattern is required. The A/
D converters have been factory-set and need
not be readjusted.
The function is shown only in conjunction with
a supporting signal source.
Note: The "Switch loop" menu item is not avail-
able unless "Source scan" is set to "Enabled".
The following four parameters are relevant to
this setting:
•
H frequency
•
V frequency
•
V total
•
Interlaced/non Interlaced
If one of these parameters changes, the moni-
tor treats it as a timing change and initiates
resynchronization via an "Auto in progress". To
prevent this from happening as a result of each
and every minor signal disturbance, the value
representing the permissible number of faulty
or changed borders must be increased in the
case of unstable signal sources.
Note: The higher the slider setting, the longer it
will take for a desired timing change to occur
(delayed by a number of milliseconds).
