ATDEC A-HDA-0818 Single Monitor Spring Arm Desk Mount

I tried to use this stand with my Samsung C43J890 43.4" 32:10 Ultra-Wide Curved Monitor. The monitor weighs 28.66 lb which this stand is supposed to handle. Even with the screws on the stand fully tightened it couldn't support the weight of the monitor. Additionally, the clamp crushed the wooden desk I was using (although the desk was inexpensive from ikea). Very disappointed in this product and returned the next day. I've seen multiple other similar reviews with the same complaint. I don't think this is a fluke.

Got this for my 30lb 49" Sony XBR49X900F because it was one of the few stands that explicitly states in its *manuals* (have to look for that paperwork link since amazon is crap about weight limit specs) that it was 'designed for heavier monitors' and is rated for '20-40lbs'. That's 20 minimum.Now, I did need to get an adapter- this thing's mount is for VESA 100x100 and that Sony TV is 200x200 (4x the size).BUT I"m happy to say it's satisfied my requirements.The main arm holds up the TV with tightening to spare. The TILT joint, while I did need to tighten that sucker up, is holding firm. And I adore the quick-lock. Fun story- the thing about hooking up a TV this size is that it's difficult to mount due to its sheer bulk, not just its weight- had a eureka moment where I just put the TV down and then was able to move the arm around behind it to slide in the mounting bracket. Quick-lock made that easy as pie. Anyway, it works well.Now, that's not to say it's perfect. Once you get to a display this heavy, the TILT mechanism they selected is sub-par. IT DOES HOLD, so that other customer that was complaining that it doesn't either didn't tighten it enough or had something go wrong, but even so this could really use a spring or some sort of force-assist to counteract gravity. As-is you have to exert ~60lbs of force to tilt it up (overcome both the force of gravity AND the force of the tightened joint that's already resisting that gravity) but <5lbs to tilt it down. I mean shoot, if you tilt it up and just let it go, the inertia alone could be enough to overcome the tightened joint's resistance and tilt the TV right back down.A minor gripe, you just have to let go of it gently after tilt changes, but there IS room for improvement going forward.Overall I'm happy with it, deserves 4 stars, and here's a pic to show I'm a real human bean.

Absolutely perfect.I bought an LG 43UD79-B along with this arm. The LG 43UD79-B is a whopping 42 inches at 28 lbs (without the stand). This arm is rated up to 40 lbs, and it handles the 43UD79-B without a hitch.When you push the arm as far back as it goes, the actual mount is slightly to the left or right of the actual base. Just be aware of this so that if you want the monitor perfectly centered when pushed far back, you'll need to clamp the mount down a little off-center. I only bring this up because you should expect the mount to "grip into" the desk :)

'rated for up to 40lb monitors' did not support my 12.5kg(27.5lb) monitor. The bracket that mounted to the back of my monitor could not support its weight for tilt/height adjustments , it would sag and face the ground , tried tightening every screw/bolt. did not work. quite the hassle.

Amazing product high end monitor arm. Only buy if youve got the money. Downside for this specific model is my monitor i have now wasnt heavy enough so i needed to add weight for it to be usable. Only get this specific arm if youve got a big monitor and heavy monitor read the actual spec sheets. And dont go under the minimum specs.
