Brightness
The brightness calibration is an automatically
process and starts with some white patterns to
measure the brightness of the specific monitor TFT
Panel. Thereafter it toggles between lower and higher
brightness values to adjust the setup value. The
brightness calibration may take about 2 to 5 minutes.

Note:
Any calibration should be done in a dark environment ( ~8 cd/m
2
) as recommended by
the ITU, SMPTE or EBU recommendations.
Note:
The BRIGHTNESS menu stops immediately when no probe is connected to the monitor
and indicates „ERROR“ in the status field!
The OSD reacts slowly to commands, cause the system is searching for a probe!
Note:
Under some circumstances the expected brightness value isn't available at the
measured monitor, may be to low or to high. In that case the lowest possible value will be
adjusted.
Note:
LCD video monitors with a CCFL lamp backlight always reacts with a „post-roll“. That
means, after setting a new value it takes some time to stabilize the backlight electronics for a
constant value. The automatic adjustment works slowly to compensate the „post-roll“ effect.
Close and save this menu step by pushing the
MENU
key once.
