Hello Peter Hofpointner,
After thorough research, testing from my end and consulting, it’s been concluded that When a call is made/ Teams notifications come in, they will always show up on the primary screen/monito
- This is the expected design behavior with new teams
- Incase you want notifications to show up on a different monitor. you will need to make it primary
++ This is the expected behavior with New Teams
The only way is changing which display is the main display in Windows or drag the pop windows.
