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.

3. Update or Reinstall the Display Drivers

If the troubleshooter fails to find any issues, it’s likely that the display drivers on your PC are outdated. In that case, you can try updating the driver and see if that helps.

If you need help with that, check our guide on how to find and replace outdated drivers on Windows and follow the steps outlined there.

If you get the “Your PC can’t project to another screen” error even after updating the display drivers, the drivers may be damaged or corrupted. You can try to fix corrupted drivers by reinstalling them on your PC.

4. Try Generic Fixes

In most cases, one of the above tips should help resolve the issue. If not, you can try some generic Windows fixes to get rid of the error.

• Run the SFC Scan: Corrupt or damaged system files can give rise to such errors. Running an SFC scan on Windows can help you find and repair such files on your PC.
