Which screws do you need? The screws with which my Samsung hangs on the wall are gone, of course. However, I still have the original packaging. I'd have to see if the right ones were included... Or has it been done in the meantime?

I use the wall mount for an LG 49UF850V and it works wonderfully. However, I don't quite achieve a right angle to the wall (about 85 degrees).

Yes, this should be compatible according to the manufacturer's page and specifications. I can't find a single picture of the back of the TV on the net unfortunately. If you could upload one to imgur.com or a similar photo host and then post the link here (add comment), this could be effectively verified. The question I have is whether the back where the 4 holes for the wall bracket are on a flat surface, or whether that surface is stepped a few mm or the whole back is on the same plane.

According to our research, the models are indeed compatible with each other.

There are different screw sets available that should fit all TVs.

Yes, that should work. With my almost bezel-less 43" Sony it works, even if it's close. If the edge is larger than 3 cm, it will probably be tight.

Max size for the bracket is 55". Therefore not recommended.

According to the compatibility list on the manufacturer's website, this bracket should be compatible with the TV mentioned: https://www.vogels.com/de-ch/c/wall-2245-schwenkbare-tv-halterung-schwarz

Looking at the second picture, my question cleared up, that should work. :)

Depending on the Curved TV model, it may or may not be VESA wall mount compatible. If you tell us your TV model, we will be happy to clarify it for you.
