Similarly, you can also configure any of the monitors as your primary display. Here’s how to change the position of monitors 1 and 2 and also set a main display in a multi-monitor setup in Windows.

A common issue in a dual-monitor setup is when you need to move your mouse cursor to the wrong side of the screen to reach the second monitor. You can fix this by rearranging the displays to reflect your monitors’ physical layout. To swap monitors 1 and 2:

1. Press Win + P to open the Project menu, then choose Extend to extend your desktop across multiple displays. If you can’t extend your display, make sure you have correctly configured your dual monitor setup .
   
2. Right-click on an empty area on your desktop and choose Display Settings. Alternatively, go to Settings > System > Display. 
3. In Display settings, click Identify. Windows will display numbered boxes on your screens to help you identify monitors 1 and 2 (and others, if you have more than two displays).

4. To rearrange the monitors, drag each display to the left/right or top/bottom position to replicate your physical setup. For example, if you have a vertical dual monitor setup, where display 2 is positioned under display 1, drag and place display 1 above display 2 to mimic the layout.
   
5. Click Apply to save the new display settings. Now, try to move your cursor across displays to test the new setup. It should feel seamless.

How to Set a Main Display in Windows

The main display (primary monitor) shows your taskbar, desktop icons, notifications, system tray, and the quick settings panel. This is also where most new apps will open by default. If you want to change your primary display so all vital content shows there, you can do so from the Settings app.

To set a default display on a dual monitor setup:

1. Press Win + I to open Settings.
2. Open the System tab and choose Display.
   
3. Here, select the display you want to set as your primary display.
4. Click to expand Multiple displays to view more options.
   
5. Select the Make this my main display option. Once done, Windows will move your taskbar items, system tray, desktop icons, and notifications to your primary display.
