Yes my bedroom tv is a hd tv but not a smart tv as it was when they first came out. It also worked in my living room and thats a smart tv. The tv in the living room would work really slow, lag or even drop and disconnet the internet when I would watch Netflix. But I put the same Chromecast on that tv and it worked a THOUSAND times better. Its just labled" bedroom" when you are searching for it and it will still connect. (One of my worries was that to would have to buy one for each tv) but apparently I dont. And it didnt say if you could or couldn't in the instructions, so that trial and error worked out great. The only problem with it is that the Chromecast comes with a plug that you have to attach to it so you have to unplug it from the electrical source and the tv and reconnecf to the other tv and an electrical source and the cord is VERY short. I just remedied it with an extension cord.
