A:AnswerYes, they do. They took my 21 yr. old Sony 150 lb TV away as long as you buy a 50" or bigger TV and the fee was 14.99, this fee may differ depending on where you live.
A:AnswerYour existing cables will be fine. I did some research reading on high end cables for any 4K, UHD or SUHD TV's and the pros are saying whether you buy a 100.00 cable or a 10.00 cable you will not see a difference. But I do suggest to research this on your own and make your own purchasing decision. I do prefer the gold plug HDMI ends which were 5.00 each and they work great, but do look into the options yourself.
A:AnswerIt does not have surround sound. It has a simulates surround sound option. In all honesty the speakers are pretty good, but you probably want to get a sound bar or a real surround sound system.
A:AnswerIt would depend on how your headphones are connected. I have a Turtle Beach headset connected into the fiber optic digital audio output. There doesn't seem to be an RCA out or an external speaker output for a 3.5mm plug.
A:AnswerYes you can apply the full HDR TO THE XBOX. I RECOMEND USING A BETTER HDMI CORD THAN WHAT MICRO GIVES YOU. YOU CAN GET ONE CHEAP FOR 40$. mAKES A BIG DIFFERENCE. BUT IF YOU DONT GET ONE, ANY GAME ADVERTISED BY MICRO WILL BE ABLE TO USE WITH 4K AND SEE GREAT THINGS.. AMAZING
A:AnswerYOU CAN HAVE THE TV PAIR TO ANOTHER REMOTE VERY QUICKLY. DURING THE SMART HUB APP SETUP IT WILL TELL YOU TO POINT THE 4K REMOTE AT THE REMOTE U WANT TO CONTROL YOUR TV WITH. TAKES ABOUT 15 SECONDS.
