A:AnswerThe TV's top holes for a wall mount are 5 inches from the top of the TV. You'll need to add at least that much to how far you want the TV from the ceiling.
A:AnswerYeah. I had one of those boxes that had multiple hdmi cords connected. Playstation,switch,xbox etc.... and cable. Until I took the cable off the box with multiple hdmi. And send the 4k cord (good to have) from cable straight to tv hdmi. Once I did that I went into settings. There is a spot to hook up your cable to tv. It will allow your samsung remote to work with your cable box aswell. Once you get the command to press up and down. You shouldn't have to do that. Fyi don't forget to hit home to get to list then scroll to the right. Hope this helps.
A:AnswerThat's a great question. The Q60, Q70, Q80, and Q90 represent the different models in the Samsung TV line up. The higher the number the better the picture quality will be.
