A:AnswerA quick G search shows the UN55MU6500FXZA mount specifications are VESA 400x400. From this mount's product description, it supports UP TO VESA 600x400.
So, YES, it will work with the UN55MU6500FXZA.
A:AnswerYes! There are actually 4 screw holes in the back of the TV. You have to unscrew the screws in the top screw holes. I used 25mm length M6 screws for the installation. 12mm is what it says in the manual but I wanted to make sure the TV does not come loose. There is enough depth in the threads for 25mm without using spacers. Hope this helps anyone who has this same question.
A:AnswerAll hardware is included with this item. Not hard to hang, but will need hammer, drill, & level, Even Thur it comes with a small one less then an inch.
A:AnswerThe back plate on this bracket is roughly 24” wide so you’ll need to mount 2x4’s horizontally on your wall studs and mount the TV bracket to the horizontal 2x4’s. BUT, before you do that, I’d double check for some wall studs between the two you found because wall studs are usually mounted 16” apart, center to center.
