A:AnswerYes. Cable is easy to connect and too is USB. Both ports will only accept the the proper input cord, so no mix up. Just look at TV before they install and note where ports are. Or look at diagram in instruction manual
A:AnswerLook up the hardware spec for the size and thread bolts in the manual that came with your TV or the Rocketfish unit and buy them at Home Depot. Manuals should also be on line.
A:AnswerIf you have 41 inches of space above your fireplace you can figure you will need 6 to 8 inches of space below where your TV begins to allow space for a sound bar. Without a sound bar you can probably cut that down to about 4 or 5 inches. Make sure to measure the height of the TV you're getting to be sure it will fit in the remaining space.
A:AnswerYes it came with many different size screws for most TV's. The thing that I learned the hard way was to attach all cables to the television before you mount it. The unit hugs the wall so closely that it is very hard to attach anything when the television is up on the wall.
A:AnswerThe mount is designed for mounting on a completely vertical only wall. it does have clips to keep the TV from falling off in an event (earthquake gets bumped etc.) But i would not recommend it for what you are describing
