A:AnswerThe OEM legged stand is the to keep the set vertical. I know the swivel stand is great we have one on a 32". The weight of a 50" may be prohibitive. Make sure you find a swivel stand that can handle the weight with a few lbs to spare since most have a GLASS base. FYI to be save a 40" table top will be good fit for this 50" flat screen. Also find a set with with the best view angle for your situation.
Good Luck
A:AnswerA 40" table top with easily accommodate this set. It come preloaded with apps and the technology to access the internet via a browser. If you have Prime and that's what you use on your Firestick you're all set. However, if you're like many and what to cut the cable still no problem. Just remember internal memory is limited so careful how much you sideload. If you don't no how visit You Tube it's all there.
Good Luck & Enjoy
