Hello davidphasson,
You've posted about using Universal Control with your iPad, specifically about the placement. For your iPad, it can only be positioned to the left, right, or below your Mac display. A Mac can be positioned above other displays. Read more from our best article here: Universal Control: Use a single keyboard and mouse between Mac and iPad
Arrange your displays
Arrange your displays to adjust where your devices think they are relative to the others. You can then move the pointer more precisely in the direction of each display.
1. On your primary Mac, choose Apple menu > System Settings (or System Preferences).
2. Click Displays.
3. If using macOS Ventura or later, click the Arrange button.
The settings window shows an image representing each device's display. Drag the image of your iPad or other Mac into position relative to the other displays: to their left, to their right, or below them. A Mac display can also be positioned above other displays. Don't see your display?
