Resolving Error: Can’t Share Desktop Across Screens

Whether you want to give a presentation in a boardroom, extend your gaming experience to a larger monitor, or simply stream Netflix from your laptop, Windows makes it relatively simple to project your screen to another display. But what if you get the “Your PC can’t project to another screen” error on Windows?

If you’ve encountered a similar error, here are some troubleshooting tips that will help fix it.

1. Rule Out Any Connection Issues

Before moving on to any advanced fixes, it’s a good idea to double-check the physical connection between your computer and the external display. Start by disconnecting the HDMI or DisplayPort cable and reconnecting it. Also, ensure that both the port and cable connector are clear of any dust particles.

If it’s just a minor connectivity issue, this should do the trick and fix the “Your PC can’t project to another screen” error on Windows.

2. Run the Hardware and Devices Troubleshooter

The Hardware and Devices troubleshooter is a useful tool that can scan your computer for any hardware-related issues and attempt to fix them. While this troubleshooter does not guarantee to fix this particular error, it’s a tool worth running nonetheless.

Since the Hardware and Devices troubleshooter is not available in the Settings app, you will need to use the Run command to access it. Here are the steps for the same.

1. Right-click on the Start icon or press Win + X to open the Power User menu.
2. Select Run from the list.
3. Type msdt.exe -id DeviceDiagnostic in the text field and press Enter.
4. In the Hardware and Devices window, click Advanced and tick the Apply repairs automatically checkbox.
5. Click Next to run the troubleshooter.
   

Allow the troubleshooter to find and fix any issues, and check if you can project to another screen after that.
