A:AnswerYes, this player works with my LG TV so no reason to think it wouldn't play through a Samsung. Get the best HDMI cable you can and you'll be good to go.

A:AnswerThis unit has an usb connection and I tried to play back a movie from my usb thumb drive, but with no success. A message appeared on the TV screen stating that my usb drive was unrecognizable. But when I connected the same usb thumb drive directly into my 4K TV's USB port, all my videos appeared and I was able to play the movies on my 4K TV successfully using my TV controller.
