Calibration Order

After the Layout Wizard has been used to congure the layout of the video wall, the order in which operations such as

measuring and calibrating displays can be modied using the Calibration Order function.

The Layout Wizard will initially congure the order to be the same as the IP address or Monitor ID assignments.

However this may not be convenient for efcient calibration, since the order may involve excessive operator movement

between displays during the process. So a different order can be selected at any time, while maintaining the display

connection order.

The Calibration Order dialog is accessed from the Edit menu.

Click on the display rectangles in the desired order to set a new calibration order. The keyboard arrow keys can also

be used to quickly select displays. When all displays have been selected in the desired order, click the Apply button.

Calibration Times

Once the displays have been connected and congured, and the layout has been congured and veried 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:

• The Use LUTs Calibration Method is used since this measures the grayscale response, and transmits the

LUT correction data to each display.

• 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 rst measure all

of the displays in order to calculate which is the dimmest display.

Likewise if Specic 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 specied 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

at a particular White Point, then if a Target Intensity level of 300 cd/m

is used, it would
