Ergotron – LX Monitor Arm, Single Monitor Desk Mount – fits Flat Curved Ultrawide Computer Monitors up to 34 Inches, 7 to 25 lbs, VESA 75x75mm or 100x100mm – Tall Pole, White

I bought this arm to replace a much cheaper version sold here on Amazon for about $100 less. It just wasn't made quite that well, and did not have the positioning abilities that I wanted, plus it wasn't tall enough for my standing desk. This arm is much, much better - it's very well made and holds my monitor very securely. It's also very easy to move the monitor to just about any position I want with very little effort. So it works for my stand up/sit down workstation, which is just what I needed. Why four stars? Because I am 5'2" tall and this are does not have the height I was looking for. Unless there's an adjustment that I don't know about, maybe. From what I've seen, it looks like the top arm is at its highest position just like in the picture on Amazon. I can get the monitor to go down, but no further up. It's impossible to tell from the very scanty instructions which joints are repositionable and which aren't, so maybe I just don't know how to get it to go higher. And I also may be too picky, but I want my monitor at eye height so I don't have to look down at all, I want to be able to look straight ahead and have my information straight in front of me. This arm is about 3" too short of that. So I have the extension arm on order, and am hoping that will give me the extra couple of inches I want for this arm to be perfect for me. However, this is just a personal preference. Other than that, this is a great piece of equipment, it looks like it's built to last forever!!!! Easy to install, too, even with the crappy instructions. I would recommend this to anyone who needs to be able to reposition a computer monitor regularly, especially if you're in a stand up/sit down workstation like I am. This arm is just perfect for that, with the exception of the height problem. And that may not be a problem for anyone else. If anyone out there knows how to adjust that top arm to go higher than the approximately 45 degree angle it's at please let me know! Overall, very well worth the money and I'm glad I shelled out the extra bucks to move up to this arm from the one I had. Update: I received the extension piece for this monitor arm that is sold here on Amazon. It's basically the same piece as the part that attaches to the pole. It took all of a minute to install and re-position my wiring, and the height problem was solved! Now my monitor is at eye height, which is exactly what I was trying to get accomplished. So now this is a five star review! If you're interested in the extension arm, it's the Ergotron 45-289-026 Mounting Extension. It's a bit pricey for what you get, but it solved my very irritating problem, so it was well worth the money. My workstation is now set up exactly the way I want it, with no eye, neck, or back strain from bending over just a little to get closer to my monitor screen. This is an excellent, heavy duty product and I can see no reason why it should ever need replacement. Here's the link: Ergotron 45-289-026 Mounting Extension

The Ergotron LX is one of the best monitor arms you can buy on the market. They are an industry brand that sell to businesses so they are reliable. Sure you can buy a way cheaper monitor arm, but this one will retain its tension, doesn’t make any noise while moving it, has great location control, and looks amazing. The installation is easy, and the amount of space it takes up is minimal. I’ve had mine for months now (this is a late review after trying it out for a long time) and I love it. It included everything necessary for installation. I am using it on a 24 inch and 27 inch monitor and it works flawlessly. It holds them well. I would say if you have the money then buy this for sure. Don’t buy a cheaper monitor arm if you can afford to buy this. It’s worth the money.

All in all this is a great articulating arm. It's very solidly built, fairly well thought out, and once set up it adjusts easily. When I unpacked, I was surprised at how heavy it was -- it is really solid. There are a couple of small caveats but they aren't enough to diminish my rating. First, the adjustment for the counter-spring for the vertical movement is next to impossible. The design calls for inserting an Allen wrench into the area behind the joint where the monitor mounting plate is attached to engage the rod which controls the spring tension. First, it is pointless to try the adjustment without the monitor in place since it is the monitor's weight one is attempting to counterbalance, and that means that the monitor will make it impossible to see into the recessed area where the wrench needs to go. There is nothing in there to guide the wrench so it is practically impossible to fit it into the hex-head on the end of the rod. Meanwhile, with the monitor and other parts of the arm in the way one cannot just continually turn the wrench -- one must turn it, then remove it and reorient it before inserting it again -- so even getting lucky at getting the wrench seated the first time won't help much. Lucky for me that the factory setting was almost perfect for my monitor so I didn't have to monkey with this that much. It is a bad design and I hope they are smart enough to change it for future offerings. My second caveat is really minor, but it just seems like they could have easily handled it better. One installation option involves installing the arm on a surface by running a bolt in the platform of the arm through a hole in the table's surface and then using a wingnut to clamp a small plate underneath the mounting surface. This works well but the bolt is very long -- I'm not sure why they need a bolt that long. In my case, there was a drawer beneath the surface where I was mounting it and the excess length of the bolt interfered with the drawer. One option to fix this is to use a shorter bolt -- that might not be easy to do, however. Where the bolt fits through the platform of the arm, it drops into a square hole and the bolt has a square section at the top of its shaft which locks into that square hole to keep the bolt from turning. It might not be that easy to find a replacement bolt with that square section as I suspect that it is not a standard part. Another option is to take a hack saw and cut off the excess portion of the bolt. Unless there is sufficient room in the mounting area to accommodate a hack saw, this would entail mounting the arm, marking the place to cut the bolt and then removing the arm to retrieve the bolt (and one would likely need a vise to hold the bolt while cutting). It would have been easy to avoid all of this, however. The bolt itself is at the bottom of the hollow upright tube which the arm is mounted on -- if they had just welded a nut to the platform and threaded the bolt through a lock-nut, then the welded nut, it could be adjusted to whatever height was desired before installing. To avoid having to install, mark the bolt, and then remove for adjustment, one could likely just estimate the length needed based on the surface on which it is to be mounted (to be fair, one could do the same with the hacksaw method but with the downside of needing to obtain a new bolt if the estimated length turned out to be too short). One last complaint involves the provisions for cable control -- the cavity in the arm for passing the cables is a little awkward to use and seems a bit small. It works well enough, however -- the real problem is that there is nothing similar for the upper arm and since a little slack is needed in the cables to allow for moving the monitor around, angling the screen, etc., one is faced with having cables drooping down behind the monitor. I alleviated this a bit by using some velcro ties to hold the cables to the upper arm so that the slack portion is only from the end of the arm to the monitor. These are minor quibbles, however, and only affect the setup. Once the arm is in place and adjusted, it works great, easily holds my 22 inch monitor, and I am very happy with it.

VERY glad I read reviews on this and the model that has replaced this one as a successor--the reviews I read said that the new replacement model (dubbed an upgrade/pro by Ergotron) is in fact just a redesign using cheaper materials and same price. I made sure to purchase this model (the older one) and am very glad that I did. The install is very quick and simple, the materials are solid and streamlined (the other ones I used had larger than necessary builds, too thick bases, etc), and moves in all the right ways. They could do a slightly better job with built-in cable management but that is easily mitigated with velcro straps or zipties etc. I definitely recommend this monitor arm, I am using it on a 34" curved ultrawide, and I did not need to adjust the settings on the unit at all--the size and weight of my monitor made it work out of the box. DEFINITELY make sure to pay attention to the different ways that you can adjust tension on the device to get your perfect setup.

the spring is of high quality. get this brand only if you frequently need to keep moving the monitor like me.

Produit de très bonne qualité, bien conçu, avec une finition robuste et élégante. L’articulation est fluide et le montage simple. Malheureusement, il n’a pas été adapté à mon écran de 47 pouces pesant plus de 20 kg. Je l’ai donc retourné. Cela dit, pour un moniteur dans la plage recommandée, c’est un excellent bras de support.

Perfect monitor arm for the Dell 49" U4919DW

Love this product. Best stand imo.

I didn't like the product, the tolerance is too big which makes my screen wobble while typing. The color is actually dark gray instead of black. On paper, I liked the features, but in practice I really just don't like the product, certainly not for that price. For more than 30 euro's less you have a secretlab monitor arm that is probably way better than this.
