The main reasons why phone screen mirroring may not work with a TV include:
- The TV input is not set to screen mirroring mode, so the TV is not ready to receive the phone's screen content.
- Trying to connect multiple devices at once, which most TVs do not support, causing connection refusal.
- Software glitches on the phone that require restarting both phone and TV to reset.
- The phone and TV are not paired or authorized properly; some smart TVs require manual pairing before mirroring.
- Physical obstructions causing wireless interference between the phone and TV.
- The phone and TV are not on the same Wi-Fi network, which is usually a requirement for screen mirroring.
- Using incompatible or improper mirroring apps or methods, e.g., some TVs use Miracast, others Chromecast, or AirPlay for Apple devices.
- Bluetooth interference, which sometimes requires turning off Bluetooth on the TV.
- Outdated device software that may disrupt compatibility and connection stability.
To fix screen mirroring issues, confirm that the TV input is set to mirroring mode, restart devices, ensure phone and TV are on the same Wi-Fi, remove other connected devices, pair devices if necessary, remove physical interference, try different mirroring apps compatible with your phone and TV, and update device software.
