# Calibration Master Display

Each calibration component in the configuration wizard will have an individual calibration multiple display in setup mode. Besides that, all those multiple displays will be merged into one window as calibration master display in setup mode. The calibration master display will also be used in manual mode.

## Master Display Layout

The default calibration master display layout may not be well arranged by default. In this case you can use master display configuration function to adjust it.

Click Configure Master Display option under AlignPlus menu to open master display configuration function, it can be opened when program is running in test mode so that you can see the effect quickly after layout is adjusted.

In the configuration page, check on Calibration first to enter into calibration display setting.

In this example, we can see that the whole display area are divided into a 2X2 zone, HECalib0 occupies the first zone, whose row and column indexes are both 0, and spans are both 1; HECalib1 takes the second zone, whose row index is 0 and column index is 1; CrossCalib uses the third zone with row and column indexes both as 1. However, the last zone is unused.

To utilize the last zone, we can swap zones of CrossCalib with HECalib1 display, and then expand CrossCalib display to take both third and fourth zone, here is the way to configure it.

Click Apply button at the button of the configuration page, there will be a dialog pop up to confirm it's a success or not. If it is not successful, the dialog will have a message to show what the error is such as:

If it says layout finished, then it is successfully applied.

The new calibration master display will look like below after the change.
