You may be able to cast a Windows 11 screen to a Roku when both devices support the required wireless-display features and are on compatible networks. Roku calls its Miracast-based feature screen mirroring. Availability varies by Roku model, Windows hardware, network configuration, and device settings.
How to Cast a Windows 11 Screen to Roku
Step 1: Check Roku screen-mirroring settings
On the Roku, open Settings > System > Screen mirroring if that menu is available. Review the screen-mirroring mode and device permissions.
Step 2: Make sure the devices are ready
Turn on Wi-Fi on the Windows 11 computer and make sure the Roku is connected normally. Wireless-display discovery also depends on compatible Wi-Fi and graphics hardware.
Step 3: Open the Windows Cast panel
Press Windows + K to open the Cast interface.
Step 4: Select the Roku
If the Roku appears, select it. The Roku may display a prompt asking whether to allow the connection.
Step 5: Confirm the connection
Accept the request on the Roku when appropriate. Windows should then begin mirroring or using the wireless display according to the supported connection mode.
If the Roku Does Not Appear
Confirm that the Roku model supports screen mirroring and that the feature has not been blocked in its settings. Restart both devices and install normal system updates. On the PC, also confirm that its wireless and graphics hardware support Miracast.
Not every Windows 11 computer supports Miracast. In that case, changing a hidden setting will not add the missing hardware capability. A wired HDMI connection or another supported streaming method may be a better option.
Casting a Video Is Different from Mirroring the Screen
Some websites and apps can send supported media directly to a Roku without mirroring the entire Windows desktop. When an app offers its own cast or Roku playback feature, that can provide better video quality than screen mirroring.
