How to Cast Windows 11 to Roku
Casting Windows 11 to your Roku device is an easy way to share your computer screen on a bigger display. All you need is a Roku device that’s connected to your TV and your Windows 11 computer. This guide will show you how to do it step-by-step, so you can start streaming photos, videos, or even presentations on your TV.
Step-by-Step Tutorial: How to Cast Windows 11 to Roku
In this section, we’ll walk through the steps to cast your Windows 11 screen to your Roku device. Follow these simple instructions to get started.
Step 1: Ensure Your Devices are on the Same Network
Make sure both your Windows 11 computer and your Roku device are connected to the same Wi-Fi network.
Having both devices on the same network ensures they can communicate with each other. If they are not on the same network, casting won’t work.
Step 2: Enable Screen Mirroring on Roku
Go to your Roku settings, select "System," then "Screen mirroring," and set it to "Always Allow" or "Prompt."
Screen mirroring options control how your Roku handles incoming screen casting requests. "Always Allow" will automatically accept requests, while "Prompt" will ask for your permission each time.
Step 3: Open Project Menu on Windows 11
Press the Windows key + P on your keyboard to open the Project menu on your Windows 11 computer.
The Project menu is where you’ll find the option to connect to a wireless display, which is what you’ll use to cast your screen.
Step 4: Select ‘Connect to a Wireless Display’
In the Project menu, click on "Connect to a wireless display" to start searching for available devices.
This step makes Windows 11 start looking for devices it can cast to. Your Roku should appear in the list if it’s on the same network and screen mirroring is enabled.
Step 5: Choose Your Roku Device
From the list of available devices, select your Roku device to start casting.
Once you select your Roku, Windows 11 will begin the casting process. You might see a prompt on your Roku asking for permission to connect.
After you’ve completed these steps, your Windows 11 screen should appear on your TV via your Roku device. You can now share whatever content you like, from family photos to presentations.
