Are there any standards/certifications for TV wall mount quality?
The answer would seem to be &quot;Yes.&quot;  In short, you'll want to look for VESA and UL certifications for monitor/TV mounting brackets.
There are VESA Flat Display Mounting Interface (FDMI) specifications for wall mounts but those seem to be mostly constrained to the &quot;geometry&quot; of the mount and its usefulness for fitting VESA-compliant monitors and televisions. The VESA standards do seem to set weight specifications that must be met in order for the mounting system to be considered VESA Certified though.
UL certifies TV/monitor mounts, and &quot;mounts that are UL-approved have undergone an additional level of testing that only adds to our peace of mind while hanging a TV off the wall. To attain UL certification, a mount is tested to at least four times the advertised weight rating. Most of the mounts we researched have an advertised weight rating of 130 to 175 pounds, which is already excessive, given the relatively light weight of today’s TVs.&quot;
