Streaming to smart TV

Hello,

First of all I apologize for my English.

I want to use Kodi on my desktop and stream it to my Samsung Smart TV. At this moment it’s possible to stream video from my local hardrive but I can’t stream video from one off the (legal) add ons. I can select my TV but nothing happens.
Can somebody help me out ?

I am using Windows 10

Any help would be much appreciated.

Ray,
