Symptoms
- TV or receiver doesn't show up as an option to mirror to
- Mirroring starts but the picture freezes or lags
- Sound plays but no picture shows, or vice versa
Likely causes
- CommonTablet and TV/streaming device not on the same Wi-Fi networkMost mirroring standards require both devices to share the same local network.
- CommonIncompatible mirroring standards between devicesNot all tablets and TVs support the same mirroring protocol (like AirPlay vs. Miracast vs. Chromecast).
- PossibleWeak Wi-Fi signal causing lag or dropped connectionMirroring is sensitive to network speed and stability.
What to do
- Confirm both the tablet and the TV or streaming device are connected to the same Wi-Fi network.
- Restart both the tablet and the TV/streaming device.
- Check that your tablet's mirroring feature (AirPlay, Miracast, Chromecast, etc.) is actually supported by your TV or streaming box.
- Move closer to the router or reduce other network traffic if lag is the main issue.
- Update the software on both the tablet and the TV/streaming device.
- If mirroring still fails to detect the device at all, check the TV's own network settings for mirroring being enabled.
When to call a pro
This is a network and compatibility issue rather than something a repair shop would fix; check the TV or streaming device's own support resources if the problem persists.
