The "Calibrate screen" function in the GP Admin module is used to display graphic objects without distortion. The following window opens:

To ensure that the calibration is carried out correctly, please proceed as follows:

1. Select how large you would like the calibration box to be. As a rule, it is sufficient to leave the standard selection at 100 x 100 mm.
2. Change the size of the dialogue box so that the box outlined in the image is enlarged to 100 x 100 mm (preferably with the mouse).
3. Click on the "Apply calibration" button.
4. Click on the "Exit" button to close the dialogue box.
5. Close the GP Manager.
6. Restart the GP Manager. Only now is the calibration applied.

Note:
Recalibration is only necessary if the resolution under Windows is changed, a different graphics card is installed or a different monitor is used. Poor calibration is present, for example, if the dimensions of the bar are not displayed correctly, i.e. the bar is compressed or stretched.
