My iPad Bluetooth does not pair with my lg tv

Is your LG TV a smart TV?

Does your LG TV support Apple AirPlay?

AirPlay works over a wireless, WiFi network and NOT Bluetooth.

If your LG TV does not have any of these features, then to mirror your iPad to your LG TV requires a wired HDMI connection using a good quality HDMI cable and this genuine Apple adapter connected to your iPad.
