Calibration Projects
The NEC Display Wall Calibrator application uses Project files to store the following information and settings:
Layouts including all of the connection settings and video wall size information.
•
Measurements for each display, including the time each measurement was taken.
•
Calibration results for each display, including the final color characteristics of each display and when it
•
was calibrated.
Calibrated Monitor Settings for each display so that settings can be restored to one or all displays if
•
necessary.
All of the display measurements and settings are unique to each display and are identified within the software by
the model and serial number of each display.
Project files can be saved at any point. By saving Projects using different file names, different configurations for the
same video wall can be stored and later restored to the displays if necessary.
Project files can also be used to keep track of when a video wall was last calibrated.
Analog Video Inputs - Important Notice
The display calibration process adjusts the digital portion of the video processing within the display. For analog
video signals such as VGA, RGB/HV, and Option-Analog, the signal is digitized within the display using an Analog-
to-Digital converter. Due to variances in analog video signal levels and offsets from the video source device, it may
be necessary to also adjust the settings for the video Analog-to-Digital conversion.
If the screens on the video wall do not match well in color after calibration, use the Test Pattern tool with the
Calibrated White setting to evaluate the displays using their internally generated test patterns. If the Test Patterns
match well, then it indicates that the analog video signal levels need to be adjusted. Use the Display Settings
dialog - Video tab to perform an automatic adjustment of the video levels.
Note: This adjustment process requires specific patterns to be displayed on the video signal in order for the display
to automatically adjust the video signal levels correctly. Failure to display the correct signal may result in the video
levels being incorrectly set and the displays may not match in color when using an analog video source.
