    Yeah that makes sence. I think I'll just replace the backet with a better one. Found this one on amazon which looks a better fit. That combined with a specialist raw plug for plaster boards weight rating. should do the trick.

    From this I don't think the single arm brackets work well for my situation. But we live and learn.

    Just fix it to something solid instead of wasting cash on another bracket surely??

    Plasterboard plugs might have great capacity but nothing to say the board they are in can handle it.

    2 bolts into something solid = forever solved.

    I had a similar issue when mounting a TV to an external wall. There seemed to just be a cavity behind the plasterboard and no way of reaching the brick exterior and studs were nowhere near where we needed? Very odd, I thought.

    Managed to secure a single arm mount for a 32" TV which is going find (although we're careful when adjusting). When we upgrade we'll need to rethink the approach.

    Cavity blocks are common, there are bolts that are designed to go in and catch which will do the job - head goes through - expands and then catches on inner of block.

    Sorry maybe I didn't describe it well enough, but there was literally just a space of air behind the plasterboard and any brick was too far to feasibly reach with any screw or fixture. I put enough holes in the wall to be sure! Whenever we upgrade through the TV location will change slightly so we may have more look then.

    You need a wider wall bracket that'll take 6 screws, zip toggle fixing are strong.

    Interesting. Piece of threaded steel bar threaded into the wall behind? Only a few quid in B&Q or similar. Just a thought.

    It’s been mentioned a couple of times but worth remembering that using plasterboard fixings the real risk is the plasterboard failing not the fixing.
    If a fixing is rated for x kg and the tv ends up on the ground the chances are the fixing will still be intact and attached to the bracket and there will be a big hole in the wall.
    Also a tv that is on a wall is pushing down on the fixing whilst one on an arm is pulling the upper fixings.

    it's going to be under the mount, and behind the TV. Paint it the same colour as the wall and it will barely be noticeable.

    These are the options from what we've been told

    1. screw into a stud - X no studs available at that location
    2. screw into solid wall behind - X there's no solid wall behind
    3. use heavy duty hollow wall fixings - X they won't support a cantilevered mount
    4. screw some wood between the studs - X too messy
    5. cut a hole in the wall and reinforce it from behind, then re-plaster. This also sounds pretty messy but it's the only one left.

    Great advice above - Can't believe the length of this discussion, at some point people need to completely disregard the "OP doesn't want to do XYZ arguments" when its been made abundantly clear that the OP hasn't a Bulls notion in this particular area.

    * No disrespect to OP of course - I'm sure they're eminently capable otherwise.

    It's gotten to the stage now that tv bracket manufacturers are including a link to this thread in their installation instructions. :D

    I've used 6 of this plasterboard anchors to hang a 55 inch TV on plasterboard wall(2 sheets).
    I's almost an year and holding strong. I think the TV has around 18kg, but the wall bracket is fixed.

    I'd only trust expandable anchors, such as these https://www.amazon.co.uk/dp/B082Y7H5PZ/ref=cm_sw_em_r_mt_dp_XJJX3Z1439A28ZR3TV3Z or similar.
    You can get them in all woodies like shops.

    Although, I'd be worried about the extendable arm's attachment point. Too much weight-bearing in such a small area. it might just snap the board off. Can you find out where the studs are? Maybe try to align with them, that would defo work well and almost any wall plug fixings would work.

    I have that setting tool and it's excellent for use with those anchors - if you try to set them just using just a screwdriver, they have a tendency to spin in the plaster, grinding an even bigger hole..

    I used them to put up a load of bookshelves in my kids rooms (though it should be noted, the bookshelves aren't putting anything like as much pulling strain on the plasterboard as an extended TV mount would)
