How to Screen Mirror Windows 11 PC to Roku TV: A Comprehensive Guide

Screen mirroring from your Windows 11 PC to your Roku TV is a seamless way to enjoy your favorite content on a larger screen. However, there may be instances where your Windows 11 PC doesn't detect your Roku TV as a compatible projection device. This guide will walk you through the troubleshooting steps and provide a clear, detailed process to help you achieve screen mirroring successfully.

Troubleshooting Your Windows 11 PC and Roku TV Screen Mirroring

Firstly, ensure that both your Windows 11 PC and Roku TV are connected to the same Wi-Fi network. The screen mirroring feature requires a stable WiFi connection to function correctly. If your devices are not on the same network, establish a connection and try again.

1. On Your Roku TV: - Enter the Settings > System > Screen Mirroring menu. - Turn on the Screen Mirroring option. This makes the Roku TV available for screen mirroring.

2. On Your Windows 11 PC: - Press the Windows key (Win K) on your keyboard to open Quick Settings. - Click on the Connect to a wireless display icon.

3. Checking for Your Roku TV: - Scan the list of available wireless display devices. Your Roku TV should appear in the list. If it does not, proceed to the next troubleshooting step.

Advanced Troubleshooting Steps

If your Windows 11 PC still does not detect your Roku TV, follow these advanced steps:

1. Resetting Devices: - Restart both your Windows 11 PC and Roku TV. This can often resolve any connectivity issues.

2. Testing Screen Casting: - Test the screen casting feature from the Roku mobile app on your smartphone or tablet. This can help identify if the issue is specific to the PC or a general network issue.

3. Third-Party Solutions: - Consider using a third-party wireless display adapter such as the Microsoft Wireless Display Adapter. These adapters can provide a direct connection for screen mirroring, bypassing potential network issues.

Alternative Methods for Screen Mirroring

For those who prefer not to use the built-in screen mirroring feature, here are alternative methods to achieve screen mirroring:

Method 1: Using an HDMI Cable

For a wired connection, use an HDMI cable to directly connect your Windows 11 PC to your Roku TV. This method is reliable and straightforward.

Method 2: Wireless Casting via Third-Party Apps

1. On Your Roku TV: - Ensure that your Roku TV has a wireless casting app installed. A common alternative is the Chromecast app.

2. On Your Source Computer: - Your source computer should have a casting app or extension installed, such as the Google Chrome extension.

3. Check Network Configuration: - Both the TV and the computer should be on the same Local Area Network (LAN). The first three octets of their IPv4 addresses should match. For example, if your TV's IP address is 192.168.1.100, your computer's IP address should be 192.168.1.101.

If the IP addresses do not match, you may need to force a static IP address on your devices to ensure they are on the same subnet.

By following these steps, you should be able to successfully mirror your Windows 11 PC screen to your Roku TV. If you encounter any further issues, feel free to ask for help or seek additional advice.
