Hi I’m wanting to put my Samsung 4K Curved 55 inch 7 series (UE55NU7500) on the wall. I’m very confused by such a overwhelming amount of different ones on the internet. Which one do I need for my TV? I don’t want to buy the wrong one and my tv coming crashing down. I’m hoping to get a handyman to carry out the installation. How do I know if they are doing it right or if they know what they are doing?
