If it's dot and dab what i suggested is by far the best option . Anything else could fail

Slightly confused about the construction of your wall as you mention dot and dab, and also suggest running the cables behind the plasterboard.

If it's dot and dab, what's behind the plasterboard? Can't be a void as dot dab is to attach plasterboard to a flat surface like brick or block, so don't know how you will feed the cables behind it.. Fixing to brick or block is easy - something like wallbolts will be very effective. If it's lightweight block e.g. thermalite then specific fixings are needed.

If it's a stud wall then the plasterboard is fixed to a timber frame with drywall screws rather than dot dab in my (limited, I admit) experience. If I wanted to attach something heavy I'd screw it directly to the wooden frame, not try to attach to the plasterboard. If necessary I'd remove the plasterboard and install extra noggins at the height required (this would also allow holes to be made in the noggins to run cable through if you want to hide it). Obviously this would involve new plasterboard, plastering and repainting.

With 'Dot n Dab' there IS usually a void between the back face of the plasterboard and the blocks that the dabs attach it too. In my house the void between the plasterboard and the blockwork is 25mm, so quite feasable to conceal cables between the two surfaces.

I've just put up a 43 inch tv on a party wall. I'm in a new build and apparently they use metal frames now so you can't bolt anything to it. That's a Taylor Wimpey house so other builders may be different but I was told it's been like that for ten years or so now. Caught me off guard when I looked inside the wall! We fixed a wooden baton behind the wall and screwed that to the plasterboard and then screwed the bracket to the baton.

My recommendation would be the invision mounts. Really simple fixings and some of them can pivot out from the wall as well as tilt but also sit really close to the wall for having that function.

Please check the vesa sizes on the back of your tv to make sure it fits the bracket. Not all brackets cater for every size. You just need to measure the distance between the screw holes on the back of the tv.

Hmm, they look interesting, never seen them before.

That said with a dot and dab wall it's much less hassle to just drill through to the solid wall behind.
