When both of your monitors on a Mac are displaying the same content, it usually indicates that the display settings are set to "Mirror Displays" instead of "Extend Desktop." This means that the same output is being sent to both monitors, resulting in a duplicated view.
To resolve this issue and have different content on each monitor, you can follow these steps:
1. Click on the Apple menu located on the top-left corner of your screen and select "System Preferences."
2. In the System Preferences window, click on "Displays."
3. In the Displays settings, navigate to the "Arrangement" tab.
4. Make sure the "Mirror Displays" option is unchecked. If it’s already unchecked and the issue persists, proceed to the next steps.
5. Drag the white menu bar from the current monitor and drop it onto the other monitor. This action will prompt the system to recognize the monitors as separate displays.
6. Adjust the monitor arrangement if needed by dragging and rearranging the blue boxes in the Arrangement tab. This will help you align the monitors according to their physical position on your desk.
7. Close the System Preferences window.
Now, each monitor should display independent content, allowing you to extend your desktop across multiple screens and have greater productivity or a wider viewing experience.
If you’ve followed these steps and the problem remains, it’s possible that there could be an issue with your cables or the specific ports you’re using. Try using different cables or ports to see if that resolves the problem. Additionally, ensure that your Mac and your monitors are all running the latest software updates, including the latest version of macOS and the most recent display drivers.
Remember, these steps are specifically tailored to Mac systems. If you’re using a different operating system, the process might vary slightly, but the general principle of adjusting display settings should remain the same.
