To attain UL certification, a mount is tested to at least four times the advertised weight rating.

UL approval: Mounts that are UL-approved have undergone an additional level of testing that only adds to your peace of mind while you’re hanging a TV on the wall.

We also kept an eye out for the smaller details that indicated a well-manufactured mount: rounded-over edges, solid-looking rivets, bolts that threaded easily, and the inclusion of all the necessary hardware. Others have multi-piece designs, a factor that adds to the installation time, creates a potential weak spot, and can limit the movement of the TV once you’ve set it up.

The best ones we looked at are built from a single piece of thick metal.

Sturdy construction: A TV mount supports a large (and expensive) TV, so we placed a strong preference on those with a robust construction.

The best mounts have small post-install level adjustment screws that let you raise or lower each side of the TV after you’ve installed it on the wall. Also, if you own an old, uneven house (like I do), you may even want the ability to tweak the TV slightly out of level, in order to align it better with the surroundings. Even just having the reference line of a nearby doorway or window is usually enough for the eye to pick up a slightly crooked TV.

With larger screens, this becomes a significant issue, particularly if you have any strong patterns on the wall, such as brick or wallpaper.

Post-install level adjustment: If you install the wall mount even just a bit out of level, it can look dramatically off once you’ve attached the TV.

The best mounts hover around the 2-inch mark, but some get the back of the TV even closer to the wall than that.

Thin profile: A TV mount shouldn’t call attention to itself, so we placed a premium on those that held the TV closest to the wall.

Whichever mount you decide on, we recommend visiting the manufacturer’s website to confirm compatibility with your specific TV. That range put the 55-inch size in the center of the mounts’ capabilities, and it encompassed a wide selection of general-use TV sizes. So we looked at mounts that supported a range of television-screen sizes from 30 to 80 inches.

Compatible with at least a 55-inch TV: TV screens are getting larger, and some TV manufacturers offer their higher-performance models only at 55 inches and higher.
