To connect to a regular TV, you need to purchase a mirroring cable separately and connect your smart device to the TV using it.
For Smart TV
To connect to a smart TV, use the wireless mirroring feature to link your TV and smart device.
However, wireless connections may be unstable and result in interruptions, so if possible, I recommend using a mirroring cable for a more stable connection.
And, Connecting the phigolf application to a Smart TV wirelessly varies depending on the manufacturer, so please contact the customer support of your TV manufacturer for specific instructions on the connection method.
