This wall mount should fit well. I use it for a 70-inch Philips TV and am very satisfied. You can't go wrong with this purchase.

I haven't looked it up yet, but the following tip could be helpful for your research. Check which VESA standard your desired TV has (technical data sheet) and look for a wall mount and check its technical data to see whether it supports exactly this Vesa standard. Vesa standards are always specified in vertical and horizontal distances. e.g. 200 x200 . means that there are screw mounts behind the TV at a distance of 20cm vertically and 20cm horizontally, so any wall mount that supports 200x200 can be installed. So you can always be sure before you buy whether the wall mount fits your TV.
