Greetings justvictor,
You can use AirPlay to stream content to a compatible device using the steps found here:
Stream audio and video from your Mac with AirPlay - Apple Support
"It’s easy to play movies, TV shows, and videos on the big screen of your TV. On your Mac, open the Apple TV app
, start the show, click
in the playback controls, then select your Apple TV or smart TV. See Control what’s playing in the Apple TV app on Mac.

Tip: Found a great video on the web you want to watch with your friends? Use AirPlay right in the Safari app. See Play web videos in Safari on Mac."
Take care.
