Ergotron – LX HD Sit-Stand Single Monitor Arm, VESA Desk Mount – for Monitors Up to 49 Inches, 14 to 30 lbs – Polished Aluminum

I just got this in last night and overall this is a great mount. Installation: Installation couldn't have been easier. The instructions were well laid out and had I actually followed them I would have saved myself some headaches. My first mistake was not installing the VESA extenders before attaching it to the monitor. This left me with 2 stripped screws, but I find that is completely my fault as I tried to force them. Once i replaced the 2 screws with new ones and did it correctly, the arm attached to the monitor easily. A Note on installation, while I didn't end up using this (see below), I found that a 1/2" hole is more than big enough to attach the mount to the desk using the grommet mount (if you don't want to use the edge clamp). Use: This thing is great with one caveat. It allows me to go from sitting to standing without issue and the 20" lift is good, but not what I would call great depending on your height. I am 5'10" and it is attached to my 30" tall desk. At it's max height, my 43" monitor is just barely at the correct height for me. If I were taller I might be concerned that it would not go high enough. I am giving it 5 stars because for my use it is a near perfect fit, but depending on your height, you might need to take into consideration it's limits on height. It's not that it doesn't go up high, but if you are 6'3", it might not go high enough for comfort when in a standing position. now, if you aren't using it for a sit/stand, I still think it is great and offers a wide range a movement. Cable management: The mount has 2 different ways of managing cables used on the 2 arms. The arm directly on the pole has a "tray that comes out and you run the cables under. At first I preferred this, but I have 4 HDMI cables, a power cable and soon to have a few USB cables. At is is, the 4 HDMI cables and the power cable are pushing that channel to it's limits. I'm not sure I'll get anymore cables in there. I realize the fact that I have so many HDMI cables may not be the norm so didn't knock any stars off. I also have some thinner HDMI cables on the way to help with that. The second method is used on the arm that attaches to the monitor. It just uses cable ties and some tabs to run the cable ties over on the underside of the arm. This means it is not as "clean" looking at the method above, but it has the added benefit of allowing more cables. I plan on sleeving all my cables in 1 sleeve to help clean this up, but it's not high priority and is probably being picky. Over all, I think the cable management is going to be great for the vast majority of people out there. Cost: This thing costs a lot! I had huge sticker shock when I went to first go and purchase it. However I have a 27lb 43" monitor (LG 43MU79-b or 43UD79-b - both are the same monitor) and this mount was the one that offered the range of movement I needed for my purpose. After receiving it and feeling the build quality I think the cost is justified, but somewhere deep inside a small piece of me still wonders how much of the cost is inflated because of the "standing desk" craze. A Note on placement: When I first set to install mine, I decided to drill some new holes in my desk. I have a corner desk and I assumed the best placement would be to put the arm in the back corner. So I drilled a 2" hole for a cable grommet and about 2" or so from it's edge drilled a 1/2" hole for the grommet adapter for the mount. This worked great for attaching the monitor to the desk and giving me a close by grommet hole to feed the cables. However, because my desk sits in a corner, I lost a lot of movement. One part of the arm would hit the wall and that would be as far back as it would go. What I found helped, was I changed out the grommet mount to the edge clamp style mount and tried a few places along the edge until I found a good spot. Unfortunately My desk's sides prevent me from using that mount permanently so once I knew where a good position was, I used that to determine where to put the grommet mount. Now, it ends up that using one of my desks existing grommet holes was the best placement so I refrained from drilling any new holes. I routed the cables to the new 2" grommet I drilled and placed an order for a 1/2" cap to cover my mistake. For those that have corner desks, what I found was that placing the arm about 13" from the back corner on either side gives me the best range of motion as the portion of the arm attached to the pole will rotate almost exactly into the corner. For those with normal desks, I would suggest you consider placing the mount off center, but if possible use the edge clamp option to position it first if you plan on using the grommet mount for permanent mounting. That way if you need to drill holes you can do so knowing it's in the right place. If I were to do this again knowing the above, I would have placed the new grommet hole I drilled much closer to the one I used for mounting for a much cleaner install. As it is, it's not bad (See picture), but I would have preferred the cables go through the desk much closer to the mount. I did contact ergotron before buying it and suggested that they look into a way to pass the cables through the mount through the same grommet hole you mount it to (some do this, but were not heavy duty enough). They said they would pass it down to their product development team, so maybe that change will come in a newer version.

I bought this to use a NEC PA271w monitor (weight, just over 20 pounds) in a sit/stand configuration. It works GREAT! Smooth action, stays put once tension is adjusted using the included tool and instructions, feels very solid and well made. Just a few bits of advice and caution: 1. Do not lock the monitor in the horizontal position when you are assembling it. The base/upright support flexes a tiny bit, and there is some play in the bearings, so some small horizontal adjustment is always needed to keep the monitor level. 2. The desktop to which the base is clamped needs to be extremely strong and stiff. There is a lot of torque on the base with a 20 pound monitor hanging to the side. 3. If you want to swing the arm from left to right in BACK of the upright post, be aware you need 13 1/2 inches of clearance from the middle of the post to the back wall. 4. There is no quick-release mount that would allow you to remove just the monitor from the arm. The arm mounts directly to the monitor. So you need to attach the monitor to the arm while the arm is off of the post. Then lift the monitor and arm assembly on to the post. If you want to adjust the collar that is on the post to a different position in order to raise or lower the arm, you need to lift the whole arm and monitor assembly off of the post. This should be a one-time adjustment, but it is a little awkward with one person, and for some might require two people.

The ergotron is an absolute beast of a monitor arm, it’s as solid as it is good looking. I purchased it to hold my Wacom drawing tablet and it holds it solidly in place while I’m drawing. The 33” reach helps push my screen out past the front edge of the desk for perfect ergonomics. I comes with numerous mounting options so you can easily meet your configuration requirements.

I've just unpacked and have not yet set up the monitor stand. My first impressions: This thing is sturdy. I've never had a monitor arm which feels this well engineered. A few disappointments though... 1) for the price paid, I think more of it should have been pre-assembled. Not only would that help ensure quality (since I've never set one up before and they have) but it seems to have been solely done this way so that the shipping box is just a tinier bit smaller. That's not a customer focused tradeoff and I have a little resentment that they made the choice in this way. 2) Step one requires an 8mm socket wrench (not included). Since there's a missing tool and I don't have one, I'm now going to have to spend a period of time without my monitor arm and with a pile of unassembled parts. Not a great experience for me, but now you know you need that tool. Instructions are pictures only. May Ikea be damned to the deepest pits of hell for popularizing this model of documentation. I'm by no means nationalistic, but the product is being sold in a market with one dominant language and words truly help with instructions when something is complex (as this is due to the first item- they could have done more pre-assembly). I don't want to put a $1500 monitor on the end of an arm if I'm worried the arm will fall apart. Building stuff is not my thing and I have concerns about whether I will do it correctly given the sixteen pages of pictograms I have to interpret. 3) The clamp seems really good- better than I was expecting. It's what you need the socket wrench for and I can't help but think that a vise closure or butterfly nuts would be just as strong but easier for assembly. 4) cable management could be better. They include two tie wraps but tie wraps are simply ugly and not reusable. They could have done better with this (as others have noted as well). 5) the parts are not numbered in the pictograms so you'll find yourself looking at a variety of similar items trying to figure out which one goes with the current diagram step.

With the new 40" 3840 x 2160 (UHD, 4K) monitors out there, at 40", as a computer programmer, I was just praying that a super quality monitor arm would be available. As others may know who use the 40" 4K's for work, as of the date I write this, those 40" 4K's (such as the Philips) are fantastic - but have terrible mounts, just fixed in position. The mount alone makes the 40" screen almost unusable after a few weeks, because you need at least a LITTLE flexibility in the positioning of the screen (tilt, side-to-side, or whatever) in order to feel comfortable for long stretches of time. I went haywire with my 40" 4K. I actually custom built a rolling monitor cart from DendreCo on Etsy, 24" by 30" with 6-inch caster wheels (that was overkill) at about 32" high and a grommet hole in the center of the top to mount this on, in which I have placed this monitor arm supporting my Philips 40" 4K. If someone is interested and posts a comment below this review I will take a picture of it. It works perfectly. I have a mobile workstation (with a mini-ITX 'shoebox' computer on the lower shelf connected wirelessly). This arm is better than I was expecting. It is essentially perfect. It has a long reach, tilts, rotates, and twists, and is 100% solid and never sinks. And is very easy to adjust into all of its positions. I can lie on the couch, sit in a chair, and even stand, and raise and lower this monitor arm to pretty much any desired position. When on the couch, the cart is at the side but the monitor arm is easily long enough to reach the arm directly in front of my face and rotate to face me while I lie back on the couch arm lengthwise along the couch like I'm about to fall asleep on the couch. In that position, the forward tilt is important (and could be a bit more, but the current forward tilt is fine). It is easy to reach forward and rotate the entire thing out of the way so I can get up off the couch without any hassle - no hard force required. On *one* of the joints, there is a bit of sustained pressure required to change the angle of the joint - this is the joint at the very middle of the top bar - this does require two hands - and essentially this joint's only purpose is to make the reach of the monitor arm longer or shorter (it has nothing to do with the height, rotation, or orientation of the monitor, though it does impact these a little bit). This monitor arm easily supports the weight and torque of my 40" Philips 4K at any position - including fully extended. I have found myself using the monitor mostly in portrait mode because you can fit SO much text on the screen vertically that way. At first I thought I'd use a 4K to fit more APPLICATION windows on the screen at one time with the assistance of a program like Divvy for Windows (which I currently have chosen as my window layout management program for use with the 4K), but now I just take advantage of the added vertical space in portrait mode and typically just have one application filling the entire (huge) monitor at a time and Alt + Tab between them. But I'm going on a tangent, as this review is about the monitor arm. But the point is that it's easy to rotate the monitor between portrait and landscape with this monitor. Another point - where the vertical piece of the monitor arm (the long bar piece that actually sticks into the desk) meets the rest of the monitor arm - this can be lowered and raised, but requires a small hex wrench, so you won't do it very often. I personally have the monitor all the way to its highest position. The reason is that even from the HIGHEST position, the monitor arm itself raises and lowers easily, and in its lowest position the monitor drops well below the table top EVEN with the monitor arm mounted at the highest position. You can drop the monitor arm all the way down until the metal bar of the monitor arm bangs into the table top so that almost half of the monitor is below the lip of the table, even with the monitor arm mounted at the highest position. Because this is easily low enough, and because I sometimes want to stand up and work (using another small table to hold my keyboard/trackball), it's more important for me to be able to raise the monitor HIGH enough to stand and use it - and with the monitor arm mounted at its highest position and then extended to its highest height, it's easily high enough to work as a standing desk. This is a rock-solid monitor arm, absolutely no slop, highly and easily adjustable with one hand, and works great with my 40" Philips 4K. Highly recommended.

I felt the price was high but I needed it, it is a quality product (best/only one I could find to mount a 30 lb. 43" monitor,) it works very well, and looks like it will last a very long time. There is one part in the assembly where you are trying to put a screw in from the bottom (blind), after the monitor is mounted, with the monitor in the way, while hoping not to cross-thread it. It is impossible until you realize you have to flip down the wire tray to be able to put the screw in straight; This was less than clear in the instructions. One major improvement they could make: Include, or offer as an option, brackets for a 200x300 VESA mount. This is what many monitors in the weight range this arm is made for will have. I had to buy a separate wall mount from Best Buy and use two of the brackets from it to convert the 200mm x 300mm to 200 x 200 for this arm.

This arm is long enough and gets low enough that I can comfortably use it with my Cintiq and a 30-inch deep desk. Or I can use it standing. It's solid. If you want to rotate the Cintiq (into portrait mode), note that the arm only rotates (into portrait mode) in one direction. Also, with the Cintiq 27 Pro, the power brick ends up sitting at the base of the arm, with enough slack to be attached to the bottom of the desk underneath where the arm is attached.

I got this arm because of the weight capacity. I have a 34 inch wide-screen monitor that weighs just over 18 pounds. I returned it as soon as I got a different monitor arm. The instructions are worse then IKEA, and while not impossible to follow, step by step instructions shouldn't be this poorly communicated. The reason for the low score is the design. This arm is crafted out of strong material, and feels very sturdy when you put it together. With some tightening it definitely holds my heavier monitor with ease. The problem is the base. A simple sturdy pole that attaches to the desk securely, but the arm itself is tightened into place on this base bar by two tiny screws about a 1/4 of an inch that you fasten about 50 degrees away from each other. So all the tension of this heavy duty arm and your monitor will be applied to one side of the bar. This led to uneven weight distribution which caused slack which I imagine will get worse over time. I took a picture to show 1 week of use. Prior the connection was seemless. Also, if you want to later lower or raise the arm on this bar, you need to unscrew and rescrew the arm in place on the bar. This scratches the metal and will leave ugly marks so best you choose a height and stick with it. Why they chose to have an amazingly built arm attach by two tiny little screws applying tension is just horrible design. If they simply made it a clamp that you tighten and it hugs the bar evenly all around, I would would have given 5 stars easily, even with horrible instructions.
