Make windows span across multiple screens

I am new to Macs, is there away to make windows span across multiple screens. I have two dell screens connect to a dell hub. When I drag a window across the screens, if does not show up on both screens, it shows partially on one screen.

MacBook Pro 14″, macOS 15.1

You may also need to go into System Settings > Desktop & Dock, and turn off the Displays have separate Spaces switch.


Extended desktop mode and being able to stretch windows across displays been around for a very, very long time – since Apple released the Macintosh II in March 1987. Mission Control and Spaces add an extra layer, where you can have multiple "Desktops", and that could interfere with using the older feature.
