This quick walkthrough shows how to use Dual Screen mode in Ableton Live, letting you view the Session and Arrangement views at once instead of constantly switching between them. Open a second window through View > Second Window, or hit Cmd Shift W on Mac (Ctrl Shift W on Windows), then drag it to a second monitor or resize both windows to share one screen.
With two windows open, you get more than a side-by-side view. Press Tab to swap which view, Session or Arrangement, appears in each window, and use Shift Tab to do the same for device and clip views.
One practical payoff worth noting: dedicating one window entirely to MIDI clip editing while the other handles arranging or session work keeps detailed editing separate from the bigger picture, which is especially useful if you're working on a large or dual monitor setup.
