NEC Display Wall Calibrator system will automatically adjust multiple displays used in a video wall so that the color characteristics closely match, thereby creating the visual illusion of a single large display. In order to accomplish this, the color characteristics of each display must be individually measured and compared to all of the other displays in the video wall. The optimal settings for each display can then be calculated so that all the displays will match after calibration.
Since each display will vary in both color and intensity (brightness), due to aging, individual components and tolerances, it is necessary to find the lowest common denominator that all of the displays are capable of collectively achieving. In other words, the video wall can only be as bright as the dimmest individual display. The color characteristics of each display are measured using a color sensor, which is connected via USB to a host PC. The sensor is placed on the screen and a series of test patterns is generated and measured. This process is repeated for all displays.
