Dear Cammie,
Welcome to the Microsoft Community
I understand how challenging it can be when a feature that previously worked without issues suddenly stops functioning. Let's work together to resolve the issue of casting your Windows 11 PC to your Roku TV.
Steps to Troubleshoot and Resolve the Casting Issue:
- Reset Network Settings: On your PC, go to Settings > Network & Internet > Advanced network settings > Network reset. This will remove and then reinstall all your network adapters and set other networking components back to their original settings. Restart your PC afterward.
- Change Projection Settings: Press
Win + Pon your keyboard to open the projection options. Select Duplicate or Extend and see if your Roku TV appears. - Disable and Enable Network Discovery: Go to Control Panel > Network and Sharing Center > Advanced sharing settings. Turn off network discovery, save changes, and then turn it back on.
- Factory Reset Roku TV: As a last resort, you can perform a factory reset on your Roku TV. This will erase all settings and data, so consider this only if other steps fail.
If you've tried all these steps and still cannot cast to your Roku TV, it may be beneficial to reach out to Roku Support for further assistance. They can provide more specialized support for compatibility and connectivity issues with their devices. I hope these steps help you get back to casting your screen from your Windows 11 PC to your Roku TV. Please let us know if you need further assistance or have any other questions.
