In order to learn how to do screen mirroring on Roku, the first thing to consider is when to use screen mirroring and when not. For those who have never tried it before, Screen Mirroring on Roku lets you stream everything from your Android device or Windows PC to your TV and use your Roku device as a receiver. Most Roku devices have screen mirroring capabilities, and the process is the same whether you’re using a cheap Roku Express or a premium Roku Ultra.
For those who need technical information, the protocol that enables this feature is called Miracast, and almost all modern Windows PCs and Android devices have access to it. (Apple devices don’t, although they do have a similar screen mirroring option called AirPlay)
Screen mirroring is usually not the best way to consume media content on a Roku as the built-in apps are much more intuitive. Even if you have your own content, you can just use a media server like Plex or Roku’s built-in media player. However, screen mirroring can be useful when you need to display something that doesn’t exactly fit in a media app or when you don’t have an internet connection.
One more thing to keep in mind is that screen mirroring is a questionable proposition at best. So, don’t be discouraged if the process doesn’t go as smoothly as you think it is.
Note that screen mirroring is a beta feature, so you may experience problems with it.
See the Roku website for an official list of certified compatible devices. In theory, any Miracast-enabled device should work, but don’t rely on it. This is one of the problems with MIracast. Even so, Miracast has improved and become more stable with the latest devices.
To enable this feature, go to your Roku’s settings screen, select System, then Screen Mirroring (Beta). Remember to check “Enable screen mirroring” option.?
How To Add Roku to your Windows PC or Android device
Then it’s time to stream from your device. On a Windows 8.1 PC, swipe in from right or press Windows key + C to access the icons. Select the device charm, then select Project. Select “Add Wireless Display” to start adding the Roku.
This only works if you’re using a modern Windows PC that includes Miracast compatible hardware.
You should see your Roku in the device list. Select it to add it to the list of available devices on your Windows PC. Windows will ask you to follow the instructions on your Roku, but it is not required. After a few seconds, the connection should be established automatically and streaming should start.
On Android, open the Settings screen, tap Display, then tap Screen. The Roku should then appear in the available list of wireless displays.

Start on the Roku
To restart streaming on Windows, select the device charm, tap Project, and your Roku will appear in the list if it’s nearby. Click or tap to project. The “Screen Mirroring” welcome screen will appear on your Roku, and then you will see your device’s display on your TV.
On Android, you can start streaming just as you added the Roku. You should see it in your quick settings list too.
Either way, all you have to do after streaming is press the home button or pretty much any other button on your Roku remote. Streaming mode will exit immediately and your home screen will appear so you can watch something else.
We’ve had problems getting this feature working in the past, but it could simply be due to the beta nature of this feature. It worked for us on the latest Roku 3 model with a Surface Pro 2.
Miracast wants effective wi-fi network without bugs. Try uninstalling virtual machine programs and anything cluttering your network if you can’t use Miracast. On Android, custom ROMs may not be able to run Miracast properly. Make sure you are using the manufacturer’s official Android version on a supported device.
In order to use Miracast devices should not run on same wi-fi network. This is because they detect and connect to Wi-Fi Direct, not over your existing Wi-Fi network. If you face issues during process, try to connect both devices to the same Wi-Fi network. This may or may not help. And since Wi-Fi is used here, sources of Wi-Fi interference can cause problems.
Any problem you have could be due to the beta nature of the screen mirroring feature on the Roku. It could also be just general Miracast problems – many manufacturers seem to have problems getting Miracast to work reliably.
But it’s still a cool feature – it means a lot of people now have Miracast-enabled devices plugged into their TVs. It could help Miracast spread and use – if it works reliably for most people.
