Do you know the dimensions of the mounting bracket as it might span two studs then no need for MDF etc
edit.. According to the lg site the bracket is 452mm wide so you might be lucky if you have studs at 400mmm centres...

I did actually buy some of those brush plates but the one behind the TV still stuck out too much for the G4 so I just put the backbox in and left it faceless behind the TV, I used a brush plate on the cable exit behind the media stand though. Cables dropped down the wall without issue thankfully.

Unbelievably the centre point of the wall meant the mount didn't hit a single stud, the holes were a few cm off and since I couldn't deal with the TV being uncentered I put a few extra noggins in and replaced the plasterboard cutout with a 12mm piece of plywood spanning the two studs. Basically my original plan and it's rock solid, no chance of it falling off and worth the piece of mind on such an expensive TV. Just a bit of a mess for the next owners to deal with but hopefully they want a TV in the same place!
 
Plywood over the stud work avoids the need to break into the plasterboard. Neodymium magnets will reveal the centre point as the pb screws dont line up. Bevel the edges and paint to match the wall. Screw brackets into plywood, it will easily hold 23 kgs.

As mentioned in the initial post and follow up posts, this particular TV sits completely flush with the wall, you cant (or wouldn't) want a piece of plywood between it and the plasterboard wall. Might as well buy a different model of TV if you go that route!

Correct, I was looking to embed it in a box (media box or recessed sockets) behind the TV but after checking with a couple of electricians they said there's no reason it can't be dropped down the wall and pulled out the bottom here in the UK, different matter in the US though. Saves me getting an electrician in to spur off a new socket.

Got it, so the outer face of the screen is flush with the wall?

I popped a screenshot in the thread on page 1 that will show it better than anything I can describe! There's basically 0 gap between the back of the very thin TV and the wall, purposefully, so you wouldn't want to go adding one.

If its not completely flush would 18mm plywood, painted, make a huge difference?
 
For those that are not understanding, these LG OLED TVs are extremely thin, the bezel is so tiny as to be basically not there, and the back of the TV is completely flat so it goes flat against the wall, in the same way that hanging a frameless mirror would work.
The mount is a custom piece supplied with the TV, and only suitable for use with that specific TV.

They also cost £2000+, so no one who buys one will want a chunk of emulsion-daubed MDF or similar shoved behind it.
