You sit down to watch a video, share photos, or give a quick presentation. Then it happens. My screen mirroring is not working. The screen stays black. The TV does nothing. Frustration kicks in fast.
This problem is more common than most people think. My screen mirroring is not working can happen on Android phones, iPhones, smart TVs, or even laptops. Sometimes it connects and drops. Other times it fails completely without warning.
The good news is this. My screen mirroring is not working issues are usually easy to fix. The cause is often Wi-Fi, settings, updates, or compatibility. This guide explains every reason clearly and shows how to fix each one step by step.
Why My Screen Mirroring Is Not Working on My TV
When my screen mirroring is not working on TV, the issue often starts with the television itself. Many modern TVs support screen sharing, but the feature may be disabled by default. A TV screen mirroring not working situation usually happens when the TV input source is wrong or wireless display settings are turned off.
A smart TV screen mirroring issue can also appear if the TV software is outdated. Older firmware may fail to recognise newer phones. In many UK homes, users report that screen mirroring not showing TV occurs after a power cut or factory reset. The TV forgets previous connections and must be set up again manually.

Common Reasons My Screen Mirroring Is Not Working
A screen mirroring problem rarely has a single cause. It is often a mix of network issues, permissions, and device limits. A common screen mirroring issue happens when devices try to connect but fail silently.
In real-world testing by consumer tech groups in the UK, over 60% of cases showed screen mirroring not connecting because both devices were on different Wi-Fi networks. Another frequent complaint is screen mirroring failed after updates. Even something simple like Bluetooth interference can trigger wireless display not working errors without clear warnings.
My Screen Mirroring Is Not Working on Android Devices
When my screen mirroring is not working on Android, settings are usually the culprit. Many users turn off casting by accident. Others experience Android screen mirroring not working after installing new apps or system updates.
A very common issue is cast screen not working because battery optimisation blocks background activity. Samsung and Pixel phones may also disable mirroring when power-saving mode is active. This causes screen share not working even though everything looks fine on the surface.
Why My Screen Mirroring Is Not Working on iPhone
If my screen mirroring is not working on iPhone, AirPlay is usually involved. Apple devices rely heavily on network discovery. Even small network delays can break the connection.
Many users report iPhone screen mirroring not working when Low Power Mode is enabled. Others face screen mirroring fails to connect because AirPlay permissions reset after an update. Apple support data shows that nearly half of AirPlay complaints come from network isolation or router settings.
My Screen Mirroring Is Not Working Due to Wi-Fi Issues
When screen mirroring not working due to WiFi, the connection cannot stay stable. Both devices must use the same network. Even a guest network can break it.
In homes with dual-band routers, one device may use 2.4GHz while the other uses 5GHz. This mismatch often causes screen mirroring keeps disconnecting or complete failure. Weak signals also trigger screen mirroring not connecting, especially in flats with thick walls.
How to Fix My Screen Mirroring Is Not Working on Smart TVs
Fixing screen mirroring not working on smart TV often starts with a restart. Turning off both the TV and phone clears temporary memory errors.
Updating the TV software is critical. Many smart TV screen mirroring issue reports disappear after firmware updates. Resetting network settings also resolves cases where the TV refuses to appear during scanning.
A short checklist many technicians follow includes checking wireless display status, refreshing the network, and reconnecting devices from scratch.
My Screen Mirroring Is Not Working After a Software Update
When screen mirroring not working after update, settings often reset silently. Permissions change. Background access gets blocked.
Real-world case studies show that Android 13 and iOS updates caused widespread screen mirroring issue reports in early releases. Restoring permissions and clearing cached connections usually fixes it. Sometimes, toggling the feature off and on again restores normal behaviour.
My Screen Mirroring Is Not Working with HDMI or Wireless Cast
Wired connections fail too. Screen mirroring not working with HDMI usually points to a faulty cable or unsupported resolution. Cheap adapters often cause mirror screen to TV problem errors.
Wireless casting can fail if the TV does not support the same protocol. This results in wireless display not working even when Wi-Fi is stable. Testing with another cable or adapter helps isolate the issue quickly.
Device Compatibility Problems When My Screen Mirroring Is Not Working
A screen mirroring compatibility problem happens when one device is simply too old. Some TVs do not support newer Android or iOS standards.
In these cases, screen mirroring not supported by device is the real answer. Checking the manufacturer’s support page saves time and frustration. Compatibility limits are common with budget TVs sold before 2018.
My Screen Mirroring Is Not Working Because of App Restrictions
Streaming apps often block sharing. This causes screen mirroring blocked by app messages or silent failures.
Netflix, Prime Video, and banking apps use digital protection. This makes screen share not working by design. Watching directly on the TV app is the only option in these cases.
Security and Permission Settings Causing My Screen Mirroring Is Not Working
Modern phones protect privacy aggressively. A screen mirroring permission issue often appears after updates or app installs.
If local network access is denied, the phone cannot see the TV. This creates a screen mirroring settings issue that looks like a network failure. Granting permissions usually fixes it instantly.
Troubleshooting Steps If My Screen Mirroring Is Not Working
Effective screen mirroring troubleshooting follows a simple order. Restart devices first. Then check Wi-Fi. Finally, review permissions and compatibility.
Tech repair shops in London report that over 70% of cases resolve within ten minutes using this approach. Random fixes waste time. A structured method works better.
When to Use Alternative Methods If My Screen Mirroring Is Not Working
Sometimes mirroring just isn’t worth the effort. If screen mirroring not connecting keeps happening, alternatives help.
HDMI adapters, Chromecast, or built-in TV apps often provide smoother playback. When screen mirroring keeps disconnecting, switching methods saves stress and time.
Frequently Asked Question
Why can’t I connect to my TV wirelessly?
Screen mirroring is not working often because your phone and TV are not on the same Wi-Fi network. Connect both devices to the same network and try again.
My phone doesn’t detect the TV at all. What now?
Screen mirroring is not working due to outdated software on one or both devices. Update your phone’s OS and the TV’s firmware for better compatibility.
Why does the connection keep dropping?
Screen mirroring is not working because of a weak or unstable Wi-Fi signal. Move devices closer to the router or reduce network interference for a steady link.
I try to connect but nothing happens. Any ideas?
Screen mirroring is not working if the devices are not compatible with each other. Check if your phone and TV support the same protocol like AirPlay or Miracast.
The screen goes black when I connect. Why?
Screen mirroring is not working due to restrictions from apps or content protection. Some streaming services block mirroring to prevent unauthorized sharing.
How come it worked before but not now?
Screen mirroring is not working after a recent update introduced a glitch. Restart both your phone and TV to clear temporary software issues.
Bluetooth is on, does that affect it?
Screen mirroring is not working because Bluetooth or VPN can interfere with the connection. Turn off Bluetooth and any VPN on your phone before trying.
Conclusion
Screen sharing problems feel annoying, but they are rarely permanent. My screen mirroring is not working usually comes down to Wi-Fi, settings, or compatibility. These issues are common in UK homes.
Once you understand the cause, fixing it becomes simple. Restarting devices, updating software, and checking permissions solve most cases. My screen mirroring is not working does not mean your device is broken.
If problems continue, use alternatives without guilt. Technology should work for you, not against you. The next time my screen mirroring is not working, you will know exactly what to do.
