How to Fix Screen Mirroring Not Working? 16 Smart Strategies Here

Screen mirroring has become an essential way to share content from a phone to a TV or PC, yet many users face situations where screen mirroring is not working. Problems such as lag, black screens, or unexpected disconnects often appear. These interruptions usually arise due to network conflicts, software mismatches, or device settings.

This page covers the reasons and 16 specific fixes, helping restore smooth connections and reliable performance.

Part 1: Why Is Screen Mirroring Not Working

Screen mirroring lets you enjoy your phone's content on a bigger screen, but it doesn't always work as expected. Understanding why it fails can help you troubleshoot and restore a smooth connection:

• Different Wi-Fi networks - Devices are not connected to the same network.
• Compatibility issues - The device may not support Apple AirPlay, Miracast, or Google Cast.
• Mirroring disabled - Screen casting is turned off on the phone or receiving device.
• Outdated software - The phone, TV, or PC system is not updated.
• Network restrictions - VPN or firewall blocks device discovery.
• System glitches - Temporary bugs interrupt the connection.
• Weak Wi-Fi signal - Unstable internet affects mirroring.
• Hardware limits - Older devices may not support wireless display.

Part 2: Fix Screen Mirroring Not Working (Phone to TV) in 10 Ways

Way 1: Check TV settings

Ensure that the proper casting feature (like Google Cast or AirPlay) is enabled in the TV's network or connection menu. Also check if options like device visibility or screen mirroring are turned on in the TV's settings, and consider restarting the TV or updating its software to clear any system glitches that might be blocking the connection.

Way 2: Try safe check #1

• On your TV, open its network settings and verify that it's truly connected to the exact same Wi-Fi network name as your phone (even mesh networks can show identical names for different nodes).
• Then on your phone, open Quick Settings and look for the Cast/Screen Cast option - if the device list is empty, that means the phone can't discover the TV on the local network, pointing to a network discovery issue rather than an app problem.

Way 3: Run a temporary hotspot test

• Turn on a mobile hotspot on your phone or another device and connect the TV/Receiver to that hotspot temporarily.
• Check if the TV becomes discoverable and mirroring works when both devices are on the hotspot network.
• If mirroring works over the hotspot but not your regular Wi-Fi, it indicates an issue with your home network's device discovery or router settings.

Way 4: Adjust router settings flags

Check if the AP isolation or client isolation is disabled, as these settings can block devices from seeing each other on the network. Next, ensure your router's multicast and UPnP features are enabled, which are required for protocols like Miracast and AirPlay. Finally, verify that both the phone and TV/PC are on the same Wi-Fi band (2.4 GHz or 5 GHz), since some routers prevent cross-band device discovery.

Way 5: Run the same node test

Try a same-node test by connecting both your phone and the TV/PC to the same Wi-Fi access point or node on your mesh network, since devices on different nodes sometimes can't discover each other.

If your router has separate SSIDs for 2.4 GHz and 5 GHz, connect both devices to the same frequency to rule out cross-band discovery issues. If mirroring works when they're on the same node, the problem is likely with your network's roaming or isolation settings rather than the devices themselves.

Way 6: Open Display Mirroring on TV

Here's how to open display mirroring on a Smart TV to help fix screen mirroring not working (steps may vary by TV type):

• Go to your TV's Settings or Home screen menu and find the Display Mirroring, Screen Mirroring, or Cast option.
• On some devices like Amazon Fire TV Stick, go to Settings > Display & Audio and enable Display Mirroring.
• Once the TV is waiting for a connection, open the cast/screen mirror feature on your phone and select the TV from the device list.

Way 7: Enable Screen Mirroring on your phone

• On Android, swipe down from the top of the screen to open Quick Settings, then tap Cast, Screen Cast, or Smart View to turn on mirroring.
• On iPhone, open Control Center, tap Screen Mirroring, and select your TV or computer from the available devices.



• Make sure the phone stays awake and doesn't switch to power-saving mode while attempting to connect.

Way 8: Use Casting Options from media applications

For using casting options from media apps to fix screen casting not working, open a supported app (like YouTube or Netflix) on your phone and look for the Cast icon within the app interface. Tapping the Cast icon lets you select your TV or compatible device directly, which can help bypass general system mirroring glitches.

This method works because many apps use more stable casting protocols that can still connect even when full screen mirroring fails.

Way 9: Try another mobile phone on the same TV

Try screen mirroring from a different mobile phone to the same TV. If the second phone connects successfully, then the problem is likely with your original phone's settings or compatibility rather than the TV itself. If the second phone also fails, the TV's mirroring feature, network, or settings may need adjustment.

Part 3: Fix Screen Mirroring Not Working (Phone to PC) in 7 Ways

Way 1: Restart your phone and PC

Restarting your phone and PC can often fix screen mirroring issues caused by temporary glitches or network conflicts. Power off both devices completely, wait a few seconds, and then turn them back on. After restarting, try connecting again, as this refreshes system processes and network connections that may have been blocking the mirroring.

Way 2: Enable wireless display on the PC

• Go to Settings > Apps > Optional Features > Add a Feature, search for Wireless Display, install it, and restart your PC.
• Once installed, open Connect or Project on Windows and select your phone to start mirroring.

Way 3: Update the network and display drivers

To update the network and display drivers to fix screen mirroring issues on a PC:

• Open Device Manager on your computer.
• Expand Network adapters and Display adapters.
• Right-click each adapter and select Update driver > Search automatically for drivers.



• Follow the prompts to install any available updates.
• Restart your PC and try screen mirroring again.

Way 4: Enable screen cast or mirroring on the phone (Android)

• Swipe down from the top of the screen to open Quick Settings.
• Look for Cast, Screen Cast, Smart View, or Wireless Display and tap it.
• Your phone will scan for nearby devices; select your TV or PC from the list.
• Make sure both devices are on the same Wi-Fi network for a stable connection.
• Keep the phone awake during the connection to avoid interruptions.

Way 5: Disable Screen Time (iOS)

On iOS, Screen Time restrictions can block screen mirroring features like AirPlay. To disable it, go to Settings > Screen Time > Content & Privacy Restrictions and turn off the toggle or adjust the settings to allow AirPlay. After disabling Screen Time restrictions, try mirroring your iPhone to the PC again.

Way 6: Disable VPN or firewall temporarily

A VPN or firewall can block the local network discovery needed for screen mirroring. To fix this, temporarily turn off any active VPN on your phone or PC and disable firewall apps or settings that may restrict connections. Once disabled, try reconnecting your phone to the TV or computer to see if mirroring works.

Way 7: Update the PC software and the phone OS

Outdated software on your phone or PC can cause screen mirroring to fail. To fix this, update your phone's operating system via Settings > Software Update and update your PC through Windows Update or your system's update tool. After both devices are updated, restart them and try screen mirroring again to ensure compatibility and stability.

Part 4: FAQs about Screen Mirroring Phone to TV/PC

Q1. Why can't my phone find my TV or PC for mirroring?

Most often it's because the phone and the TV/PC are not truly on the same Wi-Fi network (e.g., guest vs main Wi-Fi or different bands) or the receiving device's mirroring feature isn't enabled.

Q2. My TV shows up but mirroring still won't connect - why?

This can happen if the casting method (AirPlay, Google Cast/Chromecast, Miracast) your phone is using isn't supported or enabled on the TV/PC.

Q3. Did something change - it used to work, but now it doesn't. What changed?

Software updates on the phone, TV/PC, or router can alter how devices are discovered or connected, causing mirroring to stop.

Q4. Why does mirroring work for some apps but not others?

Some apps use their own casting functions (like YouTube's Cast icon) which can succeed even when full screen mirroring fails due to protocol or network issues.

Q5. Could the network be blocking mirroring even if Wi-Fi is connected?

Yes - router settings like AP/client isolation, VPNs, or firewalls can prevent the phone and TV/PC from discovering each other.

Q6. My screen mirroring shows a black screen or drops after connecting - why?

This may be due to unstable Wi-Fi, handshake problems between devices, or app/content restrictions like DRM protections.

Q7. How can I test whether the TV or my phone is at fault?

Try mirroring from a second mobile device or test with another TV/PC - if multiple phones fail on the same receiver, the issue is likely on the TV or network side.

Q8. Is screen mirroring supported between different platforms (e.g., iPhone > Android TV)?

Native mirroring may not work cross-platform due to different protocols (AirPlay vs Cast/Miracast), so a third-party app could be required in mixed ecosystems.
