A:AnswerNo, the TV is 36" and legs are at 30". You could try it without the legs if you could find a way to support it. I did that once before on a smaller TV.
A:AnswerWe got it because we got rid of cable. We are using YouTube tv and we just plugged it into the wall. It connects to our WiFi and our computers through Bluetooth. No router for sure. Not positive about the hot spot but it would make sense that would be an easy connect.
A:AnswerYes you can mount your 40 inch Samsung Tizen flat screen TV on wall mount. Must be compatible to support 40 inch and up. Purchased from Amazon. Model # PIMF5,(X003B8JWS5) Hope this is helpful.
