Hello. I'm going to mount a 46" TV on a swivel wall bracket. The TV weighs 24 kg and the bracket itself 5 kg. It's rated for 50 kg, so that's not a problem. The problem is the wall. It's made of lecablock with studs and plasterboard. I was, of course, planning to mount it on the studs, but since the bracket only spans a maximum of 44 cm between screw holes, I can only attach it to a maximum of one stud (and then it wouldn't be in the center either).
The problem is also that the distance from the plasterboard to the lecablock is about 6 cm (including single plasterboard). Molly plugs don't sound like an option unless you want to wake up one night to find the TV has fallen and large gaping holes in the plasterboard.
Since it's swivel, I'll be out about 50 cm, which means extra weight to consider.
What would you do? Should I try to find some extra long plug to use in the lecablock, or is there some other smart solution?

1. Molly or similar will also work in single drywall, if installed correctly.
2. Even a sturdy screw into a stud will prevent it from falling to the floor.
3. Long aerated concrete screws, like https://www.bauhaus.se/lattbetongsk...H1slJ5bpbOStXkIZJLL2MdrcJ-JHR0_YaAjRIEALw_wcB, can be pre-drilled and driven straight through everything, guaranteed to hold.
4. If you are super-anxious, mount a plyfa board to attach the bracket.

At intervals, use a spacer tube and drill a larger hole that the tube fits into in the plasterboard. Thick-walled tubes of one meter can be purchased at the hardware store, which you cut to size yourself. But, if you have a stud around the middle of the bracket, drill 2 new holes in it and insert some large screws, then place 4 Molly in the regular mounting holes and you are 100% secure.
