Screen mirroring technology can be great if you don’t have a smart TV but are still eager to stream video on to the big screen.

With this feature, you can have whatever there is on your compatible Windows 10 phone or tablet’s display to be mirrored on the TV with the help of a Roku steaming device or Roku TV.

Also, it just isn’t about mirroring videos but anything that is displayed on the Windows 10 device can be easily replicated on the TV. That includes images, music, web pages, and almost everything else.

In such a scenario, the TV itself turns out to be an extension of the Windows 10 device, with whatever being on the display of your Windows device getting reflected on the TV as well.

The mirroring technology used by Roku is based on the Miracast standards, which establishes a stable communication between devices such as a laptop, smartphone, or tablet to external displays such as a TV, a projector, or a monitor.

All of it happens wirelessly, which is why Miracast is also regarded as HDMI over Wi-Fi.

Also, while Windows 10 comes with built-in support for Miracast, there are some versions that don’t. Hence, a good first step would be to check if your Windows 10 device is Miracast ready before you’d want to start mirroring.

How to check if your Windows 10 device is Miracast enabled

Wireless connect

  • Type Connect in the Cortana search box. From the search result, select Connect
  • A new window will open with the following message if your Windows 10 installation supports Miracast: xyz is ready for you to connect wirelessly (where xyz is the name of your device).
  • However, you will know it’s on the contrary if you get to see this message: This device doesn’t support Miracast, so you can’t project to it wirelessly.

Also, you will have to set things up first on your Windows 10 device and establish a connection with your Roku TV. You will also have to be sure your Roku device supports screen mirroring.

You can do that by pressing the Home button on Roku remote and select Settings > System > System update > Check Now.

How do I mirror Windows 10 to Roku?

Screen mirroring from a Windows 10 device:

The process is really easy so that you can start mirroring within just minutes. Before you start, you will have to enable screen mirroring on your Roku device. Here is how you do that:

Click on the Home button on your Roku remote and select Settings from the list of options on the left. Select Screen mirroring to enable the option. That’s all.

Next, here are the steps to be followed with your Windows 10 device.


  • Launch Action Center: You can do that by simply clicking on the bottom right-most corner. This is relevant irrespective of whether you have Tablet mode enabled or disabled on your Windows 10 device. For Windows 10 mobile, Action Center can be launched simply by swiping down from the top.
  • Select the Connect option: It should be showing at the bottom of the Action Center. If not, click on the Expand link along the bottom to reveal all the options you have in the Action Center.
  • You should now be able to see a list of all wireless displays and audio devices you have in your vicinity.
  • Click on your Roku device and follow on-screen instructions thereafter.

The above will lead to your Roku device to display an on-screen prompt on your TV where you will need to choose from one of the following options:

  • Always accept: Selecting this will add your Windows 10 device to the list of Allowed devices so that each time you connect your device to a Roku, there won’t be this prompt anymore. You will get to start mirroring the right way.
  • Accept: This makes for a sort of one-time arrangement where the contents get mirrored on the Roku device for the present moment only. For each subsequent attempt, you will have to make a choice again.
  • Ignore: This, of course, blocks the current connection request so that you won’t be able to mirror the contents on your Roku device.
  • Always ignore: This again is the harshest step as your device gets blacklisted forever on the Roku device and is added in the Blocked devices There won’t be any on-screen prompts displayed on the TV at all during all subsequent attempts.

The point to note here is that the above setting including the list of Allowed or Blocked device list can be changed to suit present requirements. Here is how you do that:

  • Click on the Home button on the Roku remote.
  • Select Settings > System.
  • Here, Screen mirroring mode will let you tinker with the on-screen prompt settings. Similarly, the Screen mirroring devices setting will let you change the status of always accepted or always blocked devices.

  • You should be able to see the display device listed here. Click on it and you are now ready to mirror your Windows 10 display on to it.

However, just in case you are unable to mirror to Roku TV, you would do well to update your Wi-Fi and display drivers. You can do that by going to Device Manager > right click on the Wi-Fi and display device > Update driver and follow on-screen instructions.
