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 thatall 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.

The host PC does not have to supply any type of video signal to the displays in the video wall, as test patterns are automatically generated within in each display. Communications with each display from the host PC are performed via either RS232 or LAN (Ethernet).

Main Features and benefits

NEC Display Wall Calibrator is available on Apple Mac OS, and Microsoft Windows.

Automatic calibration

NEC Display Wall Calibrator communicates with the display monitors directly using either RS232 or a LAN (Ethernet) connection. All adjustments to the display settings are performed automatically using this communications link. It is not necessary to manually configure the displays as all of the necessary settings are made by the software.

Internal Test Patterns

Displays are calibrated using internally generated test patterns. This simplifies the operation by allowing calibration to be performed automatically without having to manually select different test patterns during the calibration process, and without the need to connect a PC to the video input of the displays.

10 bit internal Look Up Tables (LUTs)

Each LCD display monitor supported by NEC Display Wall Calibrator features three internal 10 bit LUTs. These tables allow very precise adjustments to be made to the display’s Tone Response Curve without reducing the number of displayable colors or introducing color banding artifacts.

Gamma Correction

As well as adjusting the Intensity (luminance) and white point of the displays, the software will also calibrate the grayscale using the internal LUTs of the displays. This means that highly accurate color can be achieved not only at 100% white, but at all steps along the grayscale. A variety of different Tone Response Curves can be applied also, from something as simple as a small simple gamma value to complex custom curves.

Flexible Connections

Displays can be connected using RS232, LAN, or in combinations of both, to the host PC used to perform the calibration. By using a wireless equipped host PC and LAN, displays can be calibrated without making any physical connections to the host PC.

Projects

All display configurations, measurements, and calibration data can be saved as a project file for later reference, re-calibration etc.

Multiple Calibration Sets

Different display monitor calibration projects can be uploaded to each group of displays allowing quick and easy switching between different calibration settings without the need to re-calibrate each display.

Informative

A Summary window shows the results of the calibration and the measurement data. This allows for detailed logging and reporting of the calibration procedure.

Flexible

NEC Display Wall Calibrator provides many features and options that make it flexible enough to be used in a large variety of video applications, including "on set" use in TV studios and full DICOM support for medical imaging.

Colorimeter function

The software features a Colorimeter function which allows direct measurements to be taken by the color sensor and the results displayed in a variety of different formats.

Scalable

Video wall sizes from a 1x1 single display, up to 100 displays or up to 30 rows or columns.

Yes. Use the Layout Wizard to create a layout with a 1x1 video wall and calibrate as normal.
Create a layout with the maximum number of rows and columns of displays. Then disable the displays in the layout that are not part of the video wall. To disable a display, right click on the icon for the display in the main window and select Disable. It may be necessary to manually re-configure the Connection settings for some of the displays since the Layout Wizard will have assigned IP addresses or IDs sequentially for all displays, including the disabled ones.
The time until the displays need to be re-calibrated will depend on many factors such as the environment and duration they are used, the age of the displays, the calibration Target settings used, and how critical the color matching requirements are. Newer displays will tend to drift more rapidly than displays that have been in use for several days or weeks. Typical re-calibration periods could be six months for most applications and as low as one month for color critical applications. If calibrating using the SpectraView Engine (SVE), the display will automatically stabilize the display color allowing for longer intervals between calibrations.
It depends on the particular type of calibration settings being used and the performance of the new display compared to the existing displays. If the new display is much brighter than the existing displays, then in most cases it is possible to only calibrate the new display in order to match the others - since it can be adjusted down in luminance to match the other displays. However, if the new display is about the same or lower brightness as the existing displays, then the existing displays may need to be re-calibrated in order to match the new display since it may now be the dimmest display.
The displays may not all match perfectly due to several reasons, such as: - The color and brightness uniformity of the screen is never perfect and will vary across the screen area. However, the color sensor is only measuring and adjusting the center of the screen. - When evaluating displays visually, we tend to look at the joints were adjacent displays meet. The edges of the displays are typically most non-uniform. - The color sensor used to measure the displays perceives color slightly differently than the human eye. Colors on two different displays that the sensor measures as being identical in value, may be visually different to the human eye. - The color of the LCD displays will vary slightly with viewing angle. So when viewing a video wall, each display will be viewed from a different angle which causes color shifts. - The colors on the LCD screen can be temporarily distorted by any pressure applied to the screen. Applying too much pressure to the color sensor during calibration can cause inaccurate color matching. In order to try and improve the color matching between displays after they have all been calibrated, first try recalibrating the worst matching display(s). If this does not improve the matching, then use the Visual Trim feature to make minor changes to the display visually.
