I think most recently manufactured tv hs dlna.
Just search your tv model on Internet then you should be able to find out.
If so, then download bubbleupnp app from play store. You can either set up another server on your computer, which I do, using plex server, which you can download for free for your pc. Or you can use your phone as the server as well.
You can control all the streaming from your pc to your tv or phone to tv right from the bubbleupnp app. Very cool. If you install the extra bubbleupnp server on your computer, you can even stream remotely. Very easy to set up and very cool. Real cool.
