Using a full-motion mount, I have a wall where my 55 inch 30lb tv will be mounted. There are 2 studs but 1 is an inch from a doorframe so not unusable.

The plan is to use 4 137b support toggle bolts in the drywall. Here are my questions:

  • Would this plan be fine since the tv isn't heavy?
  • is a full-motion mount a good idea and if the answers no, what about a flat mount?
  • could I just use 1 stud that is slightly off center for the full-motion mount?

Materials

Tv mount

Toggle bolts

I can't find a link but the package says they hold 137 lb on 1/2 inch drywall.

NO, JUST NO

I wouldn't recommend this in general. I especially don't recommend it with a full motion mount. Why? Because in addition to various engineering calculations that will tell you how 30 lbs. becomes some larger amount in some aspect (I don't understand all the math, but trust me on this), there is a huge problem that people will, despite their claims to the contrary, inevitably pull on the TV stressing the mounting hardware far more than the 30 lb. weight would imply.

Just don't do this.

Studs should be every 16". Possibly every 24". If you really truly can't get the mount to hit two studs then you have other options:

  • Cut open the drywall. Add some 2x4 cross-pieces between studs at the height of the TV mount. Replace the drywall. Patch and paint. Install the TV mount to the cross-pieces.
  • Cut a piece of plywood to span at least two studs. Mount it to the studs. Paint it to match the drywall, assuming at least some of the plywood would be visible with the TV mount and TV installed. Install the TV mount on the plywood.
