The by far easiest method is to install the Steam Link app on the TV. Though, Samsung removed the app a few years ago for some reason. (Yup, i too had a Samsung TV, though likely my last.)

The next easiest method, though not wireless, is to get a dock or USB hub and then use a HDMI cable.

Alternatively, if you are a little tech-savvy, you could boot into desktop mode on the SD and see if you can get Moonlight (please excuse the reddit link) to work, though I have no experience with that tool.
