I can give you three manners to display/connect netflix on/to TV.
1 - You can connect to netflix by HDMI cable from Notebook to TV. (This is the easier way). I'm sure.
2 - Every TV that owns a HDMI input might get a netflix shown on its screen. Just by purcheasing a Ezcast dongle (https://www.iezvu.com
) could be a big deal. Even If that TV is not a Smart TV that thing become it reality. The most known brand of it is called Chromecast, but I hostely prefer Ezcast. It's up to you.
3 - If your TV is a smart tv I think there is on section of Apps on there. You can find it out by clicking its remote or app control. In order to connect/cast your netflix to your Smart TV, firstly you should be sure that your TV is connected on the same wifi network that you smartphone or the other device that your prefer use is. Once it, you have to download and open netflix app and click on the button casting. Do it Like you would do with youtube app. In this Way the netflix will open in your TV out, If that TV owns a Netflix app.
4 - Connect by HDMI cable from Xbox to TV. Xbox owns a Netflix app
5 - There is many other devices with Netflix app. You can get it by wifi or cable connection
