Understand casting, mirroring and compatible devices. These steps are designed to help you troubleshoot or compare options using your own compatible device and an authorised viewing service.
Understand casting, screen mirroring and when each method works best. The steps below are written for people using a typical UK home connection, with no specialist equipment or advanced technical knowledge assumed.
Know the difference between casting and mirroring
Casting typically instructs a supported television or receiver to play content directly, while mirroring reproduces what appears on your phone screen.
Not every app permits both methods. Some content protection and platform restrictions prevent casting or mirroring.
Check the connection
Compatible casting devices often need to be on the same local network. Keep both devices updated and check that the television supports the chosen casting method.
If the devices cannot discover each other, check Wi-Fi isolation, VPN behaviour and local network permissions for the relevant app.
Choose the appropriate playback method
For long viewing sessions, direct playback on the TV app often reduces interruptions compared with leaving the phone screen active.
If the app supports casting, use its built-in Cast or equivalent button rather than relying on a generic screen mirroring tool.
Troubleshoot lag or failed connections
Restart both devices, reconnect to Wi-Fi and check app permissions. Make sure you have not accidentally connected to a guest network that isolates local devices.
If an app blocks external display use, check the service’s published compatibility information rather than attempting to bypass protection.
