Hello,
Here are some settings you might want to check:
Display Settings:
- Right-click on the desktop and select "Display Settings."
- Check the arrangement of your displays. You can drag and drop the display icons to represent the physical layout of your monitors.
- Make sure that "Extend these displays" is selected if you want to use multiple monitors.
To find the settings for multitasking in Windows, go to Start > Settings > System > Display > Multiple Displays: Get more done with multitasking in Windows
