Enabling Screen Mirroring on Roku

Problems Mirroring Windows Screen
We’ve found there are many problems when mirroring your Windows screen to the Roku. It just doesn’t work as expected.
Here are some tips if the Windows computer won’t connect to the Roku:
- Restart the Roku by going to Settings > System > System restart.
A personal note about this. I have a Roku Streaming Stick that will only allow a Windows connection once. If another attempt is made it requires a restart every time. I haven’t found a fix for this. This doesn’t happen for me on my TCL Roku TV or my Roku Ultra box.
- Make sure the latest Windows updates are installed. You can do this by going to Start > Settings > Update & Security.
- Make sure the latest RokuOS updates are installed. You can do this by going to Settings > System > System update.
- Update the network and display adapter drivers on your Windows PC. You can do this from device manager. Expand Display adapters and Network adapters. Open the display adapter and network adapter you use, go to the Driver tab then choose Update Driver.
- Reset Windows network settings by going to Settings > Network & Internet > Status > Network reset.
- Reset Windows Firewall by going to Settings > Network & Internet > Status > Windows Firewall > Restore firewalls to default.
I hope this tutorial has helped you connect and mirror your Windows screen to your Roku TV or Roku device.
