Why Is Screen Mirroring Not Working On Your Roku?(10 Fixes)

Screen mirroring allows you to mirror your Android or Windows screen on your Roku TV wirelessly.

So, when it’s not working, you might suffer since it won’t be able to cast your device’s screen to your big screen.

To fix your screen mirroring, you should start by knowing why it’s not working.

Why is Screen Mirroring not working on my Roku? Your Miracast, wireless network drivers, or operating systems could be outdated. If that’s not the issue, your Roku device is stuck in limbo, or your network is set to “Public.” It’s also possible that your device isn’t Miracast enabled, or system errors are hindering your system’s efficiency.

So, screen mirroring technology can give you the best watching experience if you can fix it quickly whenever you encounter a hitch.

Read on for more on the underlying causes of the problem, how you can fix each of them with ease. Check out the list of the Best Streaming Devices on Amazon now!

Why Won’t My PC Connect to My Roku?

• Miracast Driver is outdated. The possible reason your PC won’t connect to your Roku is that your Miracast Driver is outdated. This error occurs when the computer uses a screen mirroring technology that the driver version doesn’t support.
• Standby mode. Your screening mirroring can also fail to work if your Roku device is stuck in limbo. Whenever the operating system considers the Roku device to be in standby mode, this error arises.
• The network is set to to “Public”. If you’ve set your network to “Public,” the Windows defender firewall can also block your connection from Roku TV. This can also cause the link to keep disconnecting.
• Outdated Windows can also hinder your PC from connecting to your Roku. It’s important to note that the connection requires a working Miracast Driver to give you the desired experience. Remember, the Windows Update supplies and maintains these drivers. So, you are likely encountering the issue due to driver issues if your Windows aren’t up-to-date.
• Outdated wireless network drivers. If you are using severely outdated wireless network drivers, you can experience this same issue. Your Miracast requires the proper framework to function efficiently. So, if you haven’t updated your network driver to the latest, you might need to act fast to sort out the problem.
• Software bugs. Another possible reason your PC isn’t connecting to your Roku is software bugs. Due to system errors, your device might appear to be in the paired devices list but fail to connect your PC to Roku.

Why Won’t My Roku TV Connect to My Laptop?

One of the probable reasons your Roku TV won’t connect to your laptop is that it doesn’t support screen mirroring.

If you have Roku Express, you should remember that only model 3900 introduced in 2017 supports screen mirroring.

The famous model 3700 Roku device won’t connect with your laptop.

At the same time, only model 3910 of the Roku Express+ devices introduced in 2017 support screen mirroring.

With model 3910, your Roku TV can only connect to your laptop if you use the HDMI output.

If you want to find your Roku device’s model, you should follow these steps:

1. Settings.
2. System.
3. About.

If your Roku TV support screen mirroring, you might not have enabled the screen mirroring option on the device.

This option allows you to cast the screen of your laptop on your Roku wirelessly.

With this, you can view your laptop screen, including web pages, music, videos, pictures, and more, to your Roku TV.

To enable the screen mirroring on Roku, you should note this:

The screen mirroring feature has defaulted on Roku devices that operate on version 7.7 or the subsequent operating systems.

If yours operates on an older OS, you should do the following:

1. Select the Settings button.
2. Select the screen mirroring button.
3. Turn on the feature.

Another possible reason your Roku won’t connect to your laptop is that you’ve set your Network to “Public.”

If that’s not the case, your Windows version or the Miracast Driver is out of date.

Software errors can cause the same issue in this case as well.

To be on the safe side, you should ensure that these operating systems are up-to-date.

You can also restart the devices to fix the software-related issues.

Some people also encounter this problem since they don’t know how to allow a screen mirroring request made from their laptops.

Roku devices display on-screen prompts across the TV screen’s bottom.

From the prompts, you should choose either Accept or Accept always if you want the Roku TV to connect to your Miracast-enabled laptop.

As you can see, some of the major issues hindering your PC from connecting to Roku are culprits here too.

Screen Mirroring Not Working on Roku, How to Fix It?

In this section, let’s see the specific ways you can fix each of the underlying reasons your screen mirroring is not working on your Roku.

Find the relevant solutions to each of the problems below.

1. Temporarily disable Windows Firewall & Network Protection

Sometimes the firewall on your computer might be stopping your mirroring from functioning normally.

Follow these simple steps to see if that is the source of the issue.

1. Open your “Control Panel”.
2. Choose “System and Security” and then choose “Windows Firewall“.
3. From the list of links on the left side of the window, choose Turn Windows Firewall On or Off.
4. Choose the “Turn Off Windows Firewall” option.
5. Click OK.
6. Close the Windows Firewall window.

2. Change the input

Try changing the input on your TV from Roku to just the television.

Selected Project (duplicate screen) on your Windows 10 laptop, and it should find your Roku device.

Then change the television input back to Roku, and your laptop should be able to find the Roku as well.

3. Use 2.4G/5G Networks

If you were previously using a 2.4G connection, try changing it to 5G, and vice versa.

Go into the modem settings and rename the 2.4G and 5G outputs to different names in order for them to show up separately when you search for them on the Wi-Fi network from the TV.

4. Update your Operating System

If you are using Windows, update the OS to its current version.

Otherwise, you might struggle to screen mirror your computer on m your Roku due to the inefficiency of Miracast drivers. To fix issues caused by this, you should do this:

1. Press Windows key + R.
2. Type ‘ms-settings:windowsupdate’ and press Enter.
3. Click on Check for updates.
4. Restart before the installation of every pending update if prompted.
5. Restart your computer once you’ve installed all the updates.

5. Disable VPN

If you happened to use the VPN while trying to connect your Roku device to your computer, try disabling it and see if it does the trick.

6. Set your Network to “Private”

As we mentioned earlier, when your Network is set to “Public,” the Windows defender firewall will interfere with your ability to access your favorite content. You can fix this issue by doing this:

1. Press and hold “I” +” Windows” keys.
2. Go to the Network & Internet section once the Settings app is opened.
3. Navigate to “Network Status” and click on “Change connection properties.”
4. If you or someone set your Network Profile to Public, change Private.
5. Restart your computer and reconnect it to Roku TV.

7. Restart your Roku device

This is a very quick, yet surprisingly effective in many cases, thing to try. To restart your Roku from Settings:

1. From the Home menu, go to the Settings menu.

3. Select the System option.

You can also do it through Roku TV Setting.

3. Choose Factory reset.
4. Factory reset everything and confirm by entering the on-screen code.

9. Remove Roku from the Connected Devices List

It triggers your operating system that your devices are getting connected.

Since this process never completes, you can experience lots of interruptions.

To solve this, you should remove and re-add your Roku wireless display adapter.

Here’s how you can do this:

1. Press Windows key + R.
2. Type “ms-settings:connecteddevices” inside the text box.
