Your TV needs to be capable of receiving a wireless mirroring signal such as Miracast or similar. Look in the manual or check the model online for specifications.
If it's not capable, you will need an external device which is capable or receiving a wireless mirroring signal such as a Blu-ray player (which has this feature), Chromecast, Amazon FireStick, etc.
