ONE STUD TV mount in plaster wall or drywall: Why only one stud?

[@juliejones6822]

Everything you explained is just great! It is every scenario I went through trying to hang a 70'' TV on a plaster wall. First mistake was buying a wall mount that needs 2 studs to attach to. 2nd mistake was using the wrong type of a stud finder. 3rd mistake was marking the wall at nail heads. And that left me unable to find a second stud that would match up with the Vespa Pattern on my TV. After 20 pilot holes hitting absolutely nothing in my wall, I finally You Tubed tutorials on plaster and lathe walls. Giving me all the answers on how to hang a 70'' TV on a plaster and Lathe wall. Number 1 problem solver is....buy a ONE Stud Wall mount. And life is good!

I recommend 1-stud mounts for every wall type now, even brick and concrete, but yes on plaster too. Sometimes it's difficult enough just to find one stud, but with these, it's all you need.

I found my nightmare began with the one stud mount in an older house. Finding one stud can be very time consuming due to all the reasons listed above. The TV actually weighed less than the mount and with one stud you must find the beam. I found the large tv mount very friendly. If you get lucky and find a stud center after many attempts Perfect. I ended up using the best of toggle bolts and the best of the Stud finder. The weight distributed no problem.

Is it a bad idea to try to run cords through plaster and lathe covered walls?

[@toolsandrepairs]

Unfortunately the kits for running power cords and low voltage wires in a hollow wall seem only to be for drywall as far as I can tell. Other than that, you may want to use a raceway on the wall surface and just paint it the color of the wall.

I can’t find a stud even with the magnet

[@toolsandrepairs]

Knock on the wall to try to find the stud. You may need to buy some wall patch and drill some exploratory holes where you think the stud is and just fill in the holes where the drill punches all the way through. If it's a small, light TV you could just use toggle bolts like flip toggles.
