The best way to do that is using screen mirroring technology. It allows you to stream content from Windows 10 PC to Roku wirelessly. Also, by screencasting your Windows PC, you can stream all the content from your PC to your TV. 

Furthermore, you don’t need to be tech-savvy to learn how to Cast to Roku from Windows 10 PC. Just follow this guide, and you will be able to connect your Windows device to your Roku TV.

How to Check Whether Your Windows 10 Device is Miracast Enabled

For mirroring the screen of your Windows device, you need the Miracast protocol.

Miracast acts like a wireless HDMI cable. It allows you to mirror your screen to another screen using Wi-Fi. That means you can watch content from your computer and display it on your television through the Roku device.

Unfortunately, while most Windows computers have the Miracast feature inbuilt, some versions don’t support Miracast.

Therefore, before heading to the screencasting process, it’s essential to check if the Miracast feature on your device is enabled or not. And here’s how you can check that:

1. Try to Cast your Screen

While this method is not much accurate, it is the quickest way to check whether Miracast is enabled on your Windows device or not.

  • Press the Windows and P keys on your PC or Laptop at a time.
  • If your device supports Miracast, you will see various options for projecting the screen. Otherwise, you will see a message to reinstall the drivers.

2. Review the Display Settings

This method is comparatively easier than the one mentioned above. However, it’s again not much accurate.

  • Go to the Start Menu and select the settings option
  • Click on the System option.
  • Now choose the Display option from the left.
  • Under the “Multiple Displays” section, look for Connect to a Wireless Display option.
  • If you see the “Connect to Wireless Display” option, Miracast is enabled on your device. Otherwise, it is not supported.

How to Cast from Windows 10 to Roku

The process of Screen Mirroring on Roku is pretty simple and barely costs you any time!

However, what’s important is to check whether your Roku is compatible with screen mirroring automatically. Roku devices running on version 7.7 or above are capable of screencasting automatically.

(If you are not aware of your Roku version, you can check it by navigating to the Settings > System > System Update > Check Now.)

Once you check the compatibility of your Roku device, you can proceed with the following steps to screen mirror your Windows device.

1. Access the Settings Menu

Let’s begin by enabling the screen mirroring option on your Roku streaming device. For that, look for the Settings option by scrolling down on the Roku home screen.

2. Select the System Option

From the Settings option, select the System option. You will find various options that you can play around with— for example, language settings, payment options, video quality, audio quality, and many more.

3. Access the Screen Mirroring Section

From the options you see, navigate to the Screen Mirroring section under the System section.

4. Set Up Your Screen Mirroring Preferences

At this point, you will get three options: prompt, always allow, and never allow for screen mirroring. [see the above image]

If you select the “prompt” option, each time you attempt screen mirroring on your Roku TV, it will notify you. If you are a little more serious about unauthorized access, this option is good to go.

The “always allow” option, as the name speaks, will always mirror the screen without notifying you. And the final option, “Never allow,” will entirely disable the screen mirroring option on your Roku.

Depending on your preference, you can select the Prompt or Always allow option from these three to enable screen mirroring and then move to the next step.

5. Connect your Device

This option varies from device to device. Mostly, Windows PCs have the “Connect to a Wireless Display” option under the Display settings option. 

But, in case you don’t find the setting or option there, you can do a simple Google search. Simply type “{your device name} screen mirroring. And you will see how to screen mirror your device.

6. Accept the Screen Mirroring Request (if necessary)

If you have set your Roku device’s screen mirroring option to “Always allow,” (as mentioned in step 4), you can skip this step.

However, if your Roku device is set to any other option, you will have to accept the device pairing request. The options you will get are “Always Allow,” “Allow,” “Block,” and “Always Block.” You can choose Allow or Always allow depending on your preference.

7. Use your Device Normally

That’s it! You have mirrored the screen of your Windows 10 PC to Roku. You can now watch the content from your device on your TV screen.

But, note that when you stream pictures, videos, etc., from your PC to Roku TV screen, the resolution will play an important role. While most latest devices change the resolution automatically, some do not offer this functionality. In such cases, you can adjust the resolution manually.
