Today, I bought you a program and I wanted to set up the way it's shown in the video below.
https://www.youtube.com/watch?v=DuIK-NuN3aY

He set up 6 different monitors / splits, with different resolutions. How is this possible? Whenever I try to configure this, settings are not saved or can not be set up as shown in the video.
1146, 1148, 1146, 880, 2560, 1920 are his resolutions.

Is this all stored in one profile or are the multiple profiles required? As far as I can see in the video, it's easy to click on the titlebar without switching to another monitor. I am using an ultra wide 34 "3440x1440px monitor, a graphic card 1070.

And yes i disabled Auto-Fill All Splits.

In addition, the video shows that on the titlebar is also a separator. Where does this option turn on?
I bought the program because I want to do exactly as it is shown in the video. I do not need other functions.

Please help me.
