The verdict

One of the few mounts that explicitly covers 85 inch and larger TVs, including 100 inch class screens. Do not rely on the VESA range alone, because the maker lists only certain patterns and excludes several common ones such as 300 x 300 and 400 x 400 mm. Check your TV's exact pattern against the list.

The Beast XXL (MI-394XL) is Mount-It!'s full-motion wall mount for very large TVs. It is listed for 75 to 140 inch screens up to 275 lb, with VESA patterns up to 1200 x 900 mm. The arm extends 38.6 inches, swivels 110 degrees, tilts 5 degrees up and 10 degrees down, and retracts to 4.3 inches from the wall. It installs on 16 inch or 24 inch wood studs or solid walls and is covered by a lifetime warranty.
