There was a supply shortage of fans during the launch of the LCD model. Valve solved this by shipping two types of fans until supply was restored. If you had one of the alternative fans, then your SD would have a pretty bad whine.
Though, Valve offered original replacement fans via. IFixIt soon after, so you could just buy the better fan and change it. I did.
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 see if you can get Moonlight (please excuse the reddit link) to work, though I have no experience with that tool.
I think genAI would be pretty neat for bit banging tests, aka. Throwing semi-random requests and/or signals at some device in the hopes of finding obscure edge-cases or security holes.
