NEC Display Wall Calibrator - UsEr’s GUiDE |
Calibration Times
Once the displays have been connected and configured, and the layout has been configured and verified in the
software, the time taken to calibrate the video wall will depend on the number of displays and some of the Target
parameters and Preference settings.
It will typically take about 30 seconds to measure each display. Once measured, the calibration process should take
about 2 minutes per display, however this can take longer if:
More than the default (16) number of
Grayscale Calibration steps
is selected in the
Preferences
.
The
Extended Intensity stabilization time
option in the
Preferences
is selected.
Note:
If the Intensity setting in the current Calibration Target is set to Maximum Possible Per Display, it is not
necessary to perform the Measurement steps. This is because each display will be calibrated to the maximum
possible Intensity that it can achieve, and only the white point will match with the other displays. So it is not
necessary to first measure all of the displays in order to calculate which is the dimmest display.
Likewise if
Specific Level
is being used for the
Intensity
setting of the current Calibration Target, and the level
value being used can be achieved by all of the displays at the specified white point, then the Measurement process
can be skipped. For example if it is known (from a previous set of measurements) that all of the displays can achieve
an Intensity of at least 400 cd/m
2
at a particular White Point, then if a Target Intensity level of 300 cd/m
2
is used, it
would not be necessary to perform the Measurement step.
The following table shows some example typical calibration times for various sized video walls:

Note:
When measuring and calibrating the video wall, the software will automatically move to the next display once
the current display has been completed. The next display will be indicated by the screen on that display flashing
alternating green and red. The software will wait until the color sensor has been placed on the display screen before
automatically proceeding with the measurement or calibration process.
Video Inputs
Each video input can have its own settings for various controls, such as Brightness, Gamma Selection, Picture
Mode etc.
During calibration the settings for the currently selected video input are automatically configured. However if other
video inputs are going to be used as well with the video wall, then the settings for those inputs will need to be
correctly configured to use the calibrated settings.
After calibration, use the
Calibration
tab on the
Display Settings
dialog to apply the calibration settings to other
video inputs.
