This should handle my 31pound 65inch TV (vesa 200x200mm), Right? Even though there is a supposed "size limit" of 47 inches, it has a "weight limit" of 33 pounds. I can't see any technical reason these wouldn't work perfectly well together. The weight seems the only major factor here, especially when I'm mounting the TV "flat" to the wall (no tilt/swivel/rotation needed).

The Mount-It! Swivel Monitor Wall Mount has a specified size limit of 47 inches and a weight limit of 33 pounds. Although your TV falls within the weight limit of 33 pounds, it exceeds the size limit of 47 inches. Therefore, this wall mount may not be suitable for your 65-inch TV despite meeting the weight requirement.
