Hello everyone!

For next month, I would like to purchase a wall mount for my television with two constraints, and I seek your help, please.
It is a Samsung 55QN97A that weighs 17kg.

1. It will be fixed to drywall. Of course, I will use Molly bolts; will that be sufficient?

2. I would like a mount that is removable, where I can pull the TV forward or even swivel it.

I found two models from the brand Vogel's at Darty, one is affordable (€100 - https://m.darty.com/m/achat/accessoires/accessoire_pour_televiseur/support_mural_pour_ecran_plat/vogel_s_tv_wall_mount_55_1.html) and the other very expensive (€300 - https://m.darty.com/m/achat/accessoires/accessoire_pour_televiseur/support_mural_pour_ecran_plat/vogel_s_thin_546.html), but I don't really trust them as they are mounted on the wall with only two screws...

What do you think? Do you know of any products that are of good quality, reliable, and around €100 max?

Thank you very much in advance!

Edith: the Inovu Are464 meets my criteria except for the price since it is still at €160 (or €150 under the LDLC brand)...

    Good evening,

    For a TV that moves forward and backward and is oriented, a solid support is required, and I don't think these dowels are sufficient...

    In my opinion, it would be better to use 40x40 battens that are 20 cm long for the four screws at the ends of the support, placed vertically, between the two rail plates.

    -- They can be placed from the front or behind the wall... By making a horizontal opening to introduce them.... Then screw them in the center, rotating them 90° to come vertical behind the wall... Screwing the battens into the plasterboard... Installing the support or a mannequin of the same size to position the super screws...
    -- Fill the opening with drywall adhesive... then finishing compound...

    Of course, you need to consider the impact on the existing decor, if applicable... but that's the idea (from experience)

      Good evening,

      Thank you for the DIY lesson! So it kind of worries me... First of all, you should know that my DIY skills are close to zero (even though I'm of Portuguese origin ^^).

      What worries me is that I feel like several of you are making me understand that on a plasterboard wall, even with 5 - 6 molly plugs, it won't be strong enough, is that right?

        Instead of buying online, get advice from a hardware store (Boulanger won't cut it, but Weldom will), they are often good at giving advice even if you end up buying elsewhere.

        In practice, for daily use, the forward-backward and up-down movement is not meant (nor easy) to be adjusted regularly, unlike the lateral movement.

        As for the cable pass-through, there are now so many connections on a TV that, in my opinion, it would be worth spending a few euros on a cable organizer close to the color of the wall (which is easily found in white, gray) or to the TV (black).

        It's true that I should go to a hardware store; they can tell me more easily what's what. Especially if they have products of this type in stock. ;)
        As for the cable, it shouldn't be too much of an issue; on Samsung TVs, there's only one when you have the One Connect box.

        I don't know about that because mine, a Samsung, isn't new, but between Chromecast, media players, set-top boxes, sound bars... there are a ton of gadgets out there.

    Good evening,

    Your question would be better suited for the forum: https://bricolage.linternaute.com/forum/

    Personally, I wouldn't use this type of bracket even in a hard material.
    There are only 2 fixing screws, and since you plan to keep the TV away from the wall, the upper screw will experience significant pulling forces.
    Opt for a bracket with more fixing points to better distribute the load.

    As for the drywall, I'm not sure. The screws will probably hold; the risk is that the drywall panel itself will give way!

      Good evening,

      Thank you for the reply. Indeed, it’s also DIY, but I would also like some advice on choosing the mount because you can find mounts for €30 and mounts for over €300... It’s hard to figure it out. ;)

      I just found out, I have a Habito type reinforced plasterboard where my TV is located.

    Good evening,

    I bought one of this style from Boulanger's in-house brand about a year ago, maybe with fewer gadgets (like a bubble level, cable pass-through) and I paid a little less for it (€99.99):

    https://www.boulanger.com/ref/8000792

    The TV is only 42 inches but it's old, a bit thick, and at least as heavy as yours.

    Very sturdy, with 6 screws for the wall mount, but I had the opposite problem, solid stone with reinforced steel to drill... now, fixing this kind of weight on drywall requires precautions...

    I was told afterwards, and I haven't gone to check, that there was a much cheaper equivalent, for example at Weldom.

      Thank you for the suggestion, I hadn't thought of the brand Essentiel B which offers products at a good quality-price ratio. ;)

      Do they have that at Weldom? I should check out the DIY stores near me then. Thanks again.

    Good evening,
    Since the plasterboard panels are fixed onto either wooden or metal reinforcements, we should try to find out where these supports are located in order to use them as support.
    Some reading:

      Thank you for this informative read. ;)

      What I am sure of is that I have metal rails and a slightly sturdier plasterboard wall where the TV is.

      Still, even putting Molly anchors on 6 points of attachment, I believe I understand that it wouldn't be enough, is that right?

    Good evening
    I am renting, I didn't want to drill holes, especially since it's a Breton house made of granite, with walls over 50 cm thick
    so I opted for a floor stand, VESA type
    adjustable in height, width and horizontal tilt, I even placed the soundbar underneath
    I think my stand is no longer available, but it's something like this:

    I am sure the TV won't fall!

      Good evening.

      Thank you, I had thought about it, but aesthetically I don't find it great. I have been a homeowner for 4 months now, I would have liked to "enjoy" it to install a wall mount. ^^

    Hello, one remark is that the number of screws distributed across the width in the upper position subjected to pull-out is predominant (there's no point in putting screws every 4 cm as this will weaken the partition; a large panel or 2 small ones makes no difference, it's the width of the panel with a maximum distribution of 50 cm that seems risky while you can use the length of the TV to cover the panels without harming the aesthetics.
    Think about how you will attach the support to the panel so that the screws do not interfere against the partition; this implies mounting the support before the wall installation with countersunk screws and ultimately, it’s the panel that will bear the weight of the whole setup.

    "Donkeys change their minds, not fools."
    Remember to put "resolved" on your message if that’s the case.

      I was thinking of placing it lengthwise, with 100cm wide and 50cm high so that I could put 3 anchors at the top and 3 at the bottom. Is that not sufficient, in your opinion?

      For the support, I was thinking of pre-drilling the aluminum plate and the wall to put in some molly screws and secure the support by driving the screws through. I thought that would strengthen the partition. Is that not the right way to proceed?

    It's less bad... it's still a compromise...

    The size of the holes and the dowels must also be a compromise...

    -- Not enough dowels and it won't hold.
    -- Too many dowels == too many holes == risk of breaking the drywall..

      Hello, the plate in the length direction of 1 m is correct. I'm using 5 anchors at the top, which also seems like a good choice for screwing. "Use screws with a female socket or hex head and wrench, if possible.
      And the anchor must not turn in the plasterboard; there is a key to lock it when screwing or a special plier.
      In my opinion, metal molly-type anchors should be fixed before the plate because they have a collar that will be compressed by the plate, as shown in the demos; and with one meter, you should expect to hit either a wooden reinforcement or a metal rail. For wood, you should use a wood screw or a standard anchor.
      We're all involved in this project; we hope everything goes smoothly!!

        Thanks everyone!

        So if I recap the steps, just to make sure I don't say anything stupid.

        1. I pre-drill my aluminum plate with 4-5 holes at the top and 3-4 holes at the bottom + holes for the TV mount.

        2. I place the aluminum plate against the wall and mark the location of my holes on it.

        3. I put the molly bolts in the wall to secure the aluminum plate AND the mount. Of course, I use a molly bolt tool to properly secure them so they don't move. For the size, I was thinking of going with 8.

        4. I attach my aluminum plate with appropriate screws. I was simply thinking of using the ones provided with the molly bolts when purchased.

        5. I then attach my mount to the plate using the previously installed molly bolts at wall level, behind the aluminum plate.

        6. Finally, I attach my TV to the mount.

        I was also thinking of adding washers to all these screws, do you think that's necessary or at least recommended?

        Hello, following the message at 6 PM, I think that 5 8mm wall plugs are quite big; it's not the diameter of the screw that matters but the width of the collar that the plug will make against the plasterboard once compressed. Let's consider some 6mm ones at the dealer with washers for the aluminum.

    Molly anchors are good... but attached to cardboard with a bit of plaster, they don't hold much either...

    It's the total surface area used that reinforces the structure... And the drywall should be sandwiched... not just used as a reference point... hence the solid fixing points, behind the drywall and with a nice size..

    You have to understand that your TV doesn’t weigh 17Kg when you pull on it or turn it... it easily gains an extra 10Kg with your movements... not to mention the clumsy gestures or the kids...

    Your Portuguese community gives you a head start... and you should easily find someone who can do it properly.

      Yes, I will take all your advice and go a bit further in my research. ;)

      I will need to find a way to properly strengthen all of this to have a solid support and avoid any problems. Thank you again!!!

      And by the way, any advice on a good model at a reasonable price? ????

        Hello, I went through the conversation about finding a support; it’s not the most difficult part. However, when it comes to the mounting, you need to be careful. No seller is going to guarantee you a solution; it’s too much of a commitment. Look for wall-mounted supports for kitchen elements; these are bars that are fixed with a multitude of screws along their length to distribute the load beyond tearing. If you can go through the partition without harming the aesthetics, with a 10 cm wide plate along the length of the support, the partition is sandwiched, and the lower fixation poses less risk because it works in compression.
        The model priced at €100 from Darty will require an adaptation with an oversized upper support to distribute the pulling forces.

        Hello,
        Thank you for this response.

        Indeed, I will need to find a viable solution to solidify all of this. The problem is not to harm the aesthetics...

    Hi

    What's behind this partition as a room?
    You can try to go through with a threaded rod, and behind you can put a shelf, or whatever you want, or just a piece of metal across, and it will be fixed with the same threaded rod ^^

        It's an interesting idea, but strangely, it makes me a little scared to go through a wall like that, even if it's drywall. ^^

        What do you think of the idea of the aluminum plate mentioned below?

    Hello,

    Following your various comments, I'm trying to find a compromise to do things right while staying within something technically feasible for me.

    One solution that seems like a good compromise would be to install an aluminum plate to solidify everything, but I'm not completely sure about it.

    If I take this plate (https://www.leroymerlin.fr/produits/menuiserie/panneau-bois-tablette-etagere-tasseau-moulure-et-plinthe/verre-verre-synthetique-et-accessoires/verre-et-plaque-polystyrene/plaque-composite-aluminium-3-mm-blanc-lisse-l-100-x-50-cm-80125533.html) and fix it to the wall (with Molly screws, right?), it will better distribute the forces and that should work, right?

    And actually, I need to make all the holes in it, especially those that will be used to fix the TV mount, then insert my Molly screws into the plasterboard and finally fix the plate and then the TV mount on top of the plate, I've got that right?
