    Hello,

    Provide more details, please.

    How the TV is connected to the board?

    Is it connected via HDMI? Make sure you are not connected to the DVI.

    Are you observing errors in the console? Could you try with unplug and plug the cable?

    Could you try with other cable also?

    Also check here for more information regarding the what is supported.
