Let’s start by making sure your setup complies with the specifications for your MacBook Pro and Adobe Premiere Elements (PE). Given that you mentioned using the most recent version of PE and that your computer is a powerful M1 MacBook Pro, there shouldn’t be a problem.
In order to view the program window on one screen and the preview window on another, you are trying to configure Premiere Elements’ dual display feature. To do this, you must take the following actions:
1. Connect your MacBook Pro to a second display by connecting an external monitor to it.
2. Open the project you wish to work on in Premiere Elements.
3. Choose the “Dual Display” choice from the Window menu.
4. The program window and the preview window should now each be in their own independent windows.
5. Drag the preview window to the secondary display and the program window to the main display.
It could be aIt may be a configuration problem or a software malfunction if you are unable to drag and drop windows. You might attempt the following troubleshooting steps:
1. Make sure your MacBook Pro is configured so the desktop may be extended to the external monitor. Make sure “Mirror Displays” is unchecked by navigating to System Preferences > Displays > Arrangement.
2. Try closing Premiere Elements and starting it again to check whether the problem still exists.
3. If the problem still exists, consider resetting Premiere Elements’ options by pressing and holding the Option and Shift keys while you run the program.
4. Last but not least, you might try updating Premiere Elements to the most recent version, which might have bug patches that could solve the problem you’re having.
I hope these steps help you get the dual display option working in Premiere Elements. If you have any further questions or run into any other issues, feel free to ask.
