It is not the Molly plug itself that sets the limitation. M5 or M6 doesn't matter. You could probably hang up a car if the screw in the Molly plug was in a steel beam. It's the construction of the Molly plug in combination with the strength of the gypsum board that limits the maximum weight. The "wings" of the Molly plug will over time eat into the gypsum board due to the movement of the TV mount. Furthermore, the gypsum board is weakened by the small angled metal wings on the plug, which are supposed to prevent it from rotating during installation.
In your case, the TV mount itself is also problematic. Since the gypsum board is the weak link, using more or heavier Molly plugs won't help. It will only weaken the gypsum board. The narrow plate against the wall also increases the torsional forces and doesn't distribute the forces optimally.
When mounting heavier objects in gypsum, a Toggler plug is preferable. It distributes the load better (over a larger area) and doesn't damage the gypsum. A Toggler plug can hold about 100-120kg per vertical load in single gypsum.
In your case, I would probably recommend that you change the TV mount to a model that spreads the load on the wall maximally (wider mount). Four Toggler plugs will suffice. No reinforcement of the wall is necessary.
Alternatively, you could fasten your existing mount to a wooden board with the same height as your existing mount but 20-30cm wide, which is then attached with four Toggler plugs. That will certainly hold. You can paint or wallpaper the wooden board or do something similar so that it is barely visible.

Of course, you have. And all of them you've mounted with molly plugs in just gypsum board. You're probably cousins with the guy who insisted he used his 10.8V Makita to mix concrete too? I've duct-taped an entire house, don't believe in nails and screws.Pear4Life said:
It seems there are several people here who have done a similar mounting as the OP and failed... considering all the responses that are coming.
Opinions are one thing, experiences are another.
Leaving the discussion with the following:
Number of mounted screens in the last 15 years: Approximately between 1500 & 2000. Number of screens that have fallen down: 0
I hope you get your screen up OP, no matter which way it comes up. And remember that everyone actually wishes you well
Happy holidays!

Happy New Year!
I should probably switch to a mount with a more evenly distributed weight or test to see what happens if the mount I have now can handle my TV. But the problem is that I would like to find one that extends 65 cm from the wall, as that's when I can rotate the TV 90 degrees at a perfect angle. I would be grateful if anyone had a recommendation and preferably not a mount over 2000 kr.

Since you have sold brackets yourself, do you have any recommendations for me, preferably one that also extends 65Okarlsson said:
I have sold that wall bracket (and others) in the store for many years and can start by stating that the arrangement for the wall bracket is poor and not something used on higher-quality brackets. On good brackets (for larger TVs) there is a plate against the wall so the force is spread out a bit more. Regarding how much weight the plug can hold, it is pulling downwards in a hook-like manner, not outward force as it is for you. What happened to a number of customers over the years was that the TV bracket against the wall became loose, I never heard of anything that fell down. Having said that, this type of bracket was mostly sold up to 32 inches, not like these large brackets.
Installing painted plywood over two studs will work great and is quick. As long as the TV is larger than 40", you will likely hide the entire board behind the TV anyway.
No, I have never mounted that bracket you have with a molly plug.Tegge said:
However, I have children and a house with drywall and extensive experience with all sorts of things that have been attached and have come loose with molly plugs.
Bookshelves, bed lamps, coat hooks, speakers.
Additionally, I know how a molly plug works and have seen a cross-section of drywall. Gypsum is more or less compressed dust.

Of course, I have not. I would guess that 75% of these are in drywall.F Finndjävel said:

Here's a suggestion for another bracket:

This is a really sturdy bracket. Usually priced at just over 2000kr.
4 mounting points. You can also drill two extra own holes for 6 mounting points.

You should be able to attach something like this to at least one stud. https://www.kjell.com/se/produkter/dator-natverk/fasten-stativ/3-ledat-vaggfaste-for-tv-32-75-p57265Tegge said:
