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 – Matte Black

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.

This mount is perfect for what I bought it for - having a lot of versatile movement of my monitor, so that it can be adjusted frequently. This mount is not a set-and-leave type, where you need to set it once and stick with that location. You can adjust it as much as you want, and it holds position. The only adjustment that may take some time to make is the position of the arm on the pole, because a ring underneath the arm must be adjusted to maintain the height position. However, the height range without adjusting the arm is already pretty significant, and I do not see that it would be necessary to adjust the arm height on the pole very often. Adjustments are smooth and they stick - I do not have problems with the monitor falling out of position after I adjust it. The other reason that I picked this particular unit (besides the ability to adjust frequently and easily) is the tall pole. This provides a larger range of movement, and if your monitor is on the upper end of the rated size scale, you will probably need it. I was really happy about this choice, and although I have not really needed that extra height yet, I am really happy that I have the potential for it. When the mount arrived in the box, my first impression was that the parts were all solid and well-made, heavy construction. Assembly was really easy (no-brainer) and when put together, it was clear that the quality construction was as solid as I thought, and all parts worked smoothly together and fit easily. Ergotron did not stinge on any of the parts - they are all solid, good quality. I mounted it to the desk with the clamp, instead of drilling holes, because the desk will be moved to a new apartment soon, and I want to have flexibility of placement in the new place. The clamp provided good stability for my monitor, and I have had no problems with vibrations or the clamp slipping while I am adjusting. I may leave it in the clamp even after moving, since I have not had any problems with it. I was torn about purchasing the dual mount so that I could have the flexibility of setting up dual monitors in the future, but ultimately decided not to. Now that I have the mount, I realize that I can buy the same mount again and mount both arms on a single pole to achieve the same setup as the dual mount system. Or I can set the mounts side by side. So, I feel I made the right choice and I am not limited. Overall summary: highly recommend! Pros: quality parts, solid construction, easy assembly, easy adjustment, adjustments hold after you make them, extra height range with tall pole, choice between clamp or through-desk mounting, rotates freely between portrait and landscape viewing (fun fact - this rotational direction is not limited at all except by your cables that will wind up if you continue to rotate - you could keep rotating indefinitely if your monitor were cordless). Cons: takes a little more time to adjust the height position of the arm on the pole (this is no big deal for me). Also, having a wall directly behind the mount will limit movement away from you to some degree, because the arm will be restricted by the wall - you will not be able to retract it as far against the wall as you would if the desk were free-standing. However, it seems obvious that you will not be able to achieve the full range of movement if there are obstructions.

I have tried many desk mount monitor arm products and this is by far the best. Sadly it is the most expensive. Here is what made a difference to me: 1: Stable (other products as well, but this one FEELS stable whereas the others do not) 2: Assembly (best in class - including heavy monitor installation) 3: Ease of use (best in class - easy to maneuver, easy to move, stays put) 4: Aesthetics (bought the aluminum version and it looks really good) 5: Quality (this is by far the heaviest, beefiest, well made product in its line) The cons list is short: 1: Price (it's expensive, but has from what I can see a best in class warranty offsetting a lot of the inherent cost) 2: The set screw ring eats into the back of the post. I wish they would have used a channel or something to help remedy the digging in. This will in time show to my room. 3: There is no limiter like the HX (however no others I have used has this to my knowledge) My setup: ----- ------------ ----- | | | | | | |2K | | 4K | | 2K| | | | | | | ----- ------------ ----- Each of the 2k 27" monitors use this product. The 43" 4k monitor uses the Ergotron HX. The 2k left back faces the room. The 4k back faces the corner of my desk. The 2k right is up against a wall. My right monitor is mounted 11" from the wall with 1/4 gap from the wall to the arm. Math is needed to get it right, so be cautious. The HX has a limiter on the arm. On the cons, I can look past the price as it is a buy once cry once item and a 10 year warranty which means this will definitely outlast my other arms I have in other rooms at a fraction of the cost increase in price over the other items I would trust my expensive monitors to. I have had this monitor setup for 6 years and will likely continue to do so for my workstation. It is PLENTY of space for all my VMs, documents, photo editing, side browser window TV, and communication platform. I expect these arms to last at least 10 years, but if they don't and the warranty does NOT cover something, I will buy another set. I do not expect any of my other monitor arms to last past 3 years. Another item to check out based on my findings: the AVTL is the 2nd heaviest duty mount I found. For non-critical mounting, that is a good mount in my opinion. HOWEVER, I do not know the US presence of the company and do not know how long the mount will last with its 3 year warranty. I am not saying this is the best mount out there but it works for me. I have another room with the AVLT Dual 13"-43" Mount. I paid less than $190 after tax. The same dual monitor setup here cost almost $650. I do expect to come close to the same cost per year on both items (with the Ergotron edging out slightly at $65 per year vs AVTL $63.33 per year if it lasts the full warranty term). HOWEVER, if you compare apples to apples and do not use a dual monitor mount, now the value is with the Ergotron. The same setup with AVTL as I have on my main workstation (3 single arm mounts) would have cost around $450 after tax whereas the full Ergotron setup set me back $955. Now the cost per year is in the favor of Ergotron for sure as one of my monitors is at the brink of breaking 33lbs (so I did not want to use the almost at limit arm from AVTL where I couldn't find their US presence easily). I hope this helps someone else out there make their decision but I do NOT have any buyers remorse (but I just got them installed today so... YMMV)

I have two of these clamped to my desk(s). They are super easy to set up and almost a toolless set up. The Arm is very adjustable and stable. It holds my mac studio monitor (13+ lbs) in place with no drift at all. The knuckle that attaches to the monitor is easily attached to the monitor with knurled thumb screws and then that can be easily placed on the swing arm. One person can do this though you might need two people with a larger monitor. I did not need to adjust the tightness of the arm because it was perfect for the weight of my mac studio monitors. I just slightly tightened the set screws holding the monitor attachment in place after i mounted the monitor. The tools to tighten the set screws and adjust arm tension are provided. The clamp that mounts the stand to your desk is hand tightened with a good size knob. I did need to cut a notch in the back trim of one of the tables to accommodate the clamp because the lip of the table was too narrow. The other table had enough clearance that it was not necessary. The overhanging edge on the table I did not need to cut was 2.25” which was enough for. the clamp to be securely mounted. The table I cut only had 1” of top overhang the edge trim which was not enough for the clamp. One last thing, it is hard to tell from the pic, but my monitors are not sitting on my desktop. I have progressive lenses so I like them low, but I slide charging and usb cables under them and I need about 1/4” clearance; they do not sag and remain in position without having to adjust.

5 stars, not because there are not better ones above this price range(e.g., Humanscale at $240plus) but because nothing seems to come cloese naywhere near or belwo this price range. The cheaper ones are no more than clugs with badly fitting parts and whose screws need to be loosened, if they haven't been stripped, if you want to move the monitor position. In its price range and above I haven't yet found a decent competitor except for the Humanscale M2 or M8. The LX is a well made, nicely designed, unit well worth the price. At first, it wouldn't hold my monitor up -- the upper arm kept sinking -- and yet my monitor, at 15.4 lbs., was well below the 20 lb. max capacity for this unit. The adjustment for the weight of the monitor is #2 on the scant pictographic instructions. The picture instructions are not the best--not the worst but. . . Anyway I searched for an adjustment to the spring-tension canister in the upper arm that counterbalances the monitor's weight. Pushing the upper arm up and the screen mount down reveals the adjustment screw head at the end of the canister and the larger supplied wrench fits it. 3 half-turns clockwise made no diff. So I added three more half-turns; better but still slowly sinking. I added a 3 more half-turns--much better. 3 more for a total of 12 half-turns and the balance was perfect. You need to ease your way up to the right number of turns to get it just right balance and to avoid overtightening. Once adjusted correctly, the montoro stays in palce but can be moved easily up and down. What's nice about this unit is that, once you have it set up, you can move the monitor around and up and down without readjusting the tension or loosening/retigthening any screws. Although, if your desk is on casters or wheels, you will want to lock them, which is a good safety rule anyway. The elevation movement is smooth and easy--you can move it up or down with one finger. The horizontal swing movement is much stiffer. It helps if you spray the two large post joints with silicone lubricant liberally and then wipe away thoroughly all of the excess. This won't make the swing movement light, but it does ease it up a bit. By post joints I mean the large joints where the upper arm meets the lower and were the lower arm meets the desk mounting post. These joints have no bearings; they have plastic sleeve-type bushings. Compared to the Humanscale: the Humanscale moves horizontally as easily as the LX moves vertically while the Humanscale moves vertically as stiffly as the LX moves horizonstally--either way I'm not sure the difference is worth the extra money for the Humanscale. This stiff horizontal movement is less than ideal but far better than what I've seen on some of the cheaper units offer. For this price I could live with stiffness given all the other postive features. The LX comes with a heavy duty clamp base and a drill-a-hole-in-the-desk grommet type mount--both come in the box. All of the parts are in a two-layer plastic strip, sealed into multiple compartments with each compartment labeled as to contents. Much better than those units that come with all the screws etc. all in one bag and you have to sort them by count and looks against their picture in the instructions. It's not quite as pretty as the Humanscale M2 or M8, which cost about 60% more, but much more nicely finished than the cheaper units I've seen up close. The LX, with less attractive desk mounting pole, has a greater range of vertical position than the Humanscale. If you can afford it, this monitor arm is a very good choice. If you can afford more, then it's a tough choice between this at its price vs the Humanscale arms at the higher prices. For the money, this is a much better deal, thus, my rating of 5 stars.
