I'm not 100% sure, but I don't remember any of the tvs at Uni being Smart tvs.
We just took an HDMI cord with a HDMI to lightning adapter on it (purchased Best Buy / Amazon) and plugged one end into our phones or iPads and the other into the TV. Instant Amazon Prime, Netflix, YouTube, whatever you want. You can even run the connection off of a computer to play dvds. Worked great, no issues. Just be sure you get a cord long enough to reach from the tv to the bed, so you don't have to get up to pause, rewind, or change the show.
