A:AnswerGo to Samsung.com for the Specifications and NOTE Samsung has great phone support to answer all pre-purchase and set up concerns. I was impressed.
A:AnswerBought a tv floor stand for sizes 32" to 55", it came with different sizes and lengths of screws, did fit one of the size. If you carefully notice, the screw threads are in the deep inside and not all the way out to the opening, so you need a smaller size than the opening, sorry don't know the actual size.
A:AnswerYes it supports the latest HDMI interface because it is 4K and it uses a higher bandwidth for 4K content. It’s also backwards compatible for older resolution devices.
