Pitch compensation
Some Screens using multiple outputs can have outputs with different pitches, especially LED video walls.
Using pitch compensation corrects the outputs with different pitches for a screen with homogeneous scaling.
Preconfig > Canvas⚓
Select a Screen.
Select an output group to set a different pitch.
The reference output group should use a 1:1 pitch.
In Pitch, set the H and V ratio of the output group compared to the reference output group.
