I had a problem selecting a wall mount for my garage on a 40" TCL. The width of the brackets is narrower, even for large TVs up to 90 inches. Then comes the issue of VESA 100x100 capability. I didn't want to risk having an off-center rail on the mount, so I decided to buy TWO AM wall mounts. They both butt together on my center stud and then the ends reach the next stud which is 16 inches apart. Problem solved - TLV centered with my raised sound system, SUPER EASY to install if you have a drill and tape measure. Cutting into the studs is very easy, masonry is more difficult as the depth needs to be >2 inches. I can't imagine some companies charging $190 for installation - if you can find studs it's very easy and you can't beat the price!
