Mounting 77" G5 to plasterboard wall

I've just bankrupted myself after buying an LG G5 after contemplating a G4, since I bought this house, literally a year ago this weekend.

What I didn't realise, is the wall I was going to mount it too, and all the walls in fact, have a slight cavity with plasterboard, for what I can only assume is for insulation purposes.

Where I want the TV, the stud is running directly through the middle, so I should be able to get the middle bolts in that. Will it be ok to use the spring toggle bolts for the sides. From some googling, it seems that quite a few people have mounted it entirely with the spring mounts, but I'd rather have some peace of mind knowing it's on a stud.

I think the gap between the brick and the plasterboard is only around 2" maybe 4", so I maybe able to some sort of long plug and bolt into the brick work?

I don't really want to cut the wall to bits if I have to, and certainly don't want some plywood behind it, as it won't sit flush.

Any ideas greatly welcome!
 

However you mention brickwork and studs. Usually you wont have both in the same wall.

I've recently mounted my 77 inch Sony oled to a plasterboard wall. I was hoping to find studs but they were either side of where the TV had to sit centrally. i used 6 of the below to mount the bracket and its rock solid. Quite scary drilling a 25mm hole in the wall to use though!

 
These TVs use a bespoke bracket for flush mounting.

In that case I think I would cut a neat verticle rectangle with a jabsaw at each end of where the bracket will go, a bit longer than the height of the bracket, screw some batten to the wall, then screw the bit of plasterboard you just cut out back to the batten, fill and paint it, then screw the bracket on top. Doesn't even have to be that neat a job as the TV will cover it.

Spring toggles can take a huge amount of weight, so I don't see why not if they are properly installed.

If you've also got some screws going into the stud I think you'll be fine.

I've done similar with some shelving that holds drinks, and that's easily had 50kg on it.
 
pretty brave fitting expensive TV on the wall one consideration is floor stand

That looks like ****. These TVs are designed to be flush mounted on the wall for a sleek look. It's not risky or brave, it's just a matter of using the correct fixings.

Sleek look with 9.3.4? :D

I'd probably pay a company (not just a one man band but well known) to get it fitted, ensure they have insurance...so if it does fall you're covered (and also protects house contents insurance for damage)

I don't have TV wall mounted (as it's front of a window ) but looking at my gear, if I imagine if it's on the wall now, and fell off, it would damage two subwoofers , a center speaker, a pair of bookshelf speakers, and possibly my tower speakers
:eek:
and of course smash the OLED. That's a few thousand trashed.

Thanks for that. My builder/carpenter friend also just recommended these too! So I think I'll give them a try for the bits not in the stud!

This is an option I did consider, but preferably don't want to go down that route if I don't really have too. I have a friend coming on Monday that's a builder/carpenter to give me a hand. Obviously it is the safest way of doing it!

After watching that video I'd get it mounting to studs, cross brace between two or three uprights.
Plasterboard just seems a unreliable mounting surface...for something that's £4000+

I just watched that video you posted. At least two of the center bolts will be in the stud already. The two on either side of that will just be using some form of plasterboard plug.

If going by that video he is using a hook type bracket with both the plugs inline of each other so that is already a lot of stress hanging forward. The TV bracket won't be doing that sort of leverage and is spread across 6 bolts (it maybe more I haven't looked properly) so I think it will be fine considering the gripit ones which I'll probably use held at least 20kg each.
