After adjusting projectors we can start with configuration of the visual. (Apologize screens in German language).
We know that there are probably much better tutorials out there but we decided to publish our way. Maybe it's helpful for some of you.
Important: As we learnd you should use separate screens. In our case screen 2, 3 and 1. Display 4 is our maintenance computer. Do not use nVidia surround in combination with P3D.
We will user Fly-Elise Immersive Calibration PRO to prepare warping and edge blending.
First we start the client.exe and select three times 1 x 1 projectors. Of course not for our maintenance display.
Then we start Immersive Calibration PRO Server and create a new project.
As we have three projectors in one row we select "No Stacking".
Our screen is curved like a horseshoe. So - surprise, surprise - we choose "Horseshoe" and "Map on projector"
In the next steps we choose the right combination of projectors (3 x 1)m, correct native solution and match remote projectors with our combination. In our case -5760 is left, 3840 is the center projector and 1920 is the right projector.
So. Now we are ready to do the major adjustments.
