Ergotron – HX Premium Heavy Duty Monitor Arm, Single Monitor VESA Desk Mount – for Flat or Slight Curved Ultrawide Monitors Up to 49 inches, 20 to 42 lbs – Standard Pivot, Polished Aluminum

I struggled to find an arm that would support my almost 33lb 4k 43" LG monitor. Sadly it is the most expensive but is among 2 that I found would work and the tolerances are DEFINITELY better for the Ergotron. Here is what I like: 1: Stable - was concerned due to the drop in nature of Ergotron HX, but the monitor does not move after mounted 2: Assembly - almost too easy; 32 lb monitor mounted solo VERY easily 3: Ease of use - very very smooth 4: Aesthetics - good looking; aluminum look only comes in white but matches the black items in the room I have well 5: Quality - clearly built to last 6: Warranty 7: Company is known and has a US presence Here is what I don't like: 1: Price - it is expensive The cost is worth it in my opinion as the company has a US presence and a good warranty - also it is the only mount where my weight is in the middle of the road. My setup: ----- ------------ ----- | | | | | | |2K | | 4K | | 2K| | | | | | | ----- ------------ ----- Each of the 2k 27" monitors use the Ergotron LX. The 43" 4k monitor uses the Ergotron HX.

This monitor arm is extremely well made, durable and a lot more heavy then I thought it would be. So, overall the construction of the arm and it's design is very well made, heavy solid materials. It comes shipped in a great packaging, it's nice to see care in how much care went into packing. The assembly is relatively easy with just 3 parts that connect with a few screws to tighten. I'm using this arm with an LG 38" Ultra Wide monitor that I believe is about 15lbs in weight and it can easily move around without struggle on the arm. If you have a lighter monitor or a smaller sized one, you may have difficulty with the arm keeping a monitor in a low position. If the monitor is light weight < 12-13lbs it may want to lift up on it's own due to the heavy spring action. I had a smaller monitor on it while waiting for my ultra-wide and it was kind of comical. I added weight to the monitor to keep it down a bit. It supports VESA 100x100 and 200x200 on the mounting bracket. I feel like this is a good standard for newer monitors. The mount is sturdy and supports a really good range of movement tilting up and down as well as a full rotation on it's side. The arm movement is really reasonable in it's range of movement. I'm even able to drop my monitor down a bit lower than the clamp. The arm assembly also includes options to mount the arm with a desk clamp, or through a drilled hole. It has good options for mounting the arm as needed. I'm really satisfied with this purchase and can see this arm lasting a really long time - probably much longer than my new monitor. I highly recommend getting it.

This is expensive, but right away, it's apparent that the quality and strength are unsurpassed. I used it on a Dell 42.5" UltraSharp U4323QE Hub monitor with built-in VESA holes. Screws and posts for many monitors are supplied, but I recommend this combination. The additional USB ports are easily accessed with this monitor arm. When installing this, my former HP 42.5 UHD Z43 monitor detached from its mount when I turned it over and dropped on the Ergotron, shattering the screen and not being covered by the extended warranty. (I am a bonehead). The Z43 required an optional external mount for VESA, which I didn't realize before I bought the monitor. Smashing the screen saved me the hassle of getting the optional add-on VESA mount from HP (and it would have been a hassle). I purchased this monitor arm because I wanted more than the HP mount, although the monitor was good. The HP monitor is a few hundred cheaper and a good one, but if you get that, take a very close look at the VESA situation, the stand on the HP I bought was not adequate for the size of the monitor. The monitor was a couple of years old so they might have corrected this, but caveat emptor. This is so much better than the shaky, poorly adjusting HP stand that I feel better about stupidly shattering the HP. Also, this monitor bolts directly onto the arm via VESA holes the HP didn't have. The resolution on the HP might have been better, but the Dell is easier to operate. It's a shame HP made a pretty good monitor and then skrimped on the stuff that makes it work ergonomically.

I bought this at a friend's recommendation so I'd finally have a proper mount for my Cintiq tablet. It's definitely on the pricier side but worth every penny. It came with everything I needed to mount my tablet off the side of my desk, and left me with a bunch of hardware should I need to mount to a larger VESA footprint or switch to a grommet mount. Assembly was quick, even after I managed to set everything up only to realize I mounted my tablet upside-down I was done in under an hour. The hold is sturdy and gives me confidence when I draw or move my tablet. And the included cable organizers are a nice touch. The desk clamp is fairly large and goes about 4 inches deep from the edge of the desk. Unfortunately the mounting bracket for my desk's legs leaves only about 2.5 inches of even mount purchase before the edge of my desk. I was able to shim the mount clamps so they hold strong, and even with the clamp bracket extending about an inch off the side of my desk, this thing is plenty sturdy for my liking. In the end, I could have fussed with cheaper mounting arms as I have in the past, but it's hard to put a price on peace of mind when dealing with higher-end monitors.

This was not willing to support a just above 20 pound monitor as it was specified for, so we used one that is 31 pounds instead. It just barely cooperates with that weight, as loosening or tightening the screws all the way to the end of one side has made the tension just enough to not point the monitor upward on its own or raise the VESA on its own. A little more than a light touch does raise the monitor in undesired positions, but if it is not interfered with at the tension we were able to get it set to, it just barely can cooperate as desired. Other than that, it appears to be a quality metal product that is well built & nicely made, aside for a misaligned monitor mount/adapter which slots into the VESA a little higher than it is supposed to due to a lip that was not cut short enough. While that does not slot perfectly, the two screws provided do hold it in place so it is bearable, otherwise it would have been wobbly without those screws. So yes, it was quite easy to assemble this product, kept the plastic washers on which the instructions failed to specify for less friction when rotating the arm, & assembled nicely. So far it is performing as intended & it has been almost a month of ownership.

I absolutely absolutely FREAKING LOVE THIS ARM. I bought it as soon as I found out we'd be working from home for a while, in an effort to finally upgrade my home setup. After I bought it I mentioned it to a friend, and she said "YES!!! I HAVE THE SAME ONE AND I LOVE IT!!" I've only had it for a couple of months, but my friend has had hers for years and it's still going strong. I have an enormous Cintiq - 24HD Touch. I was warned that if the weight of the screen to be supported is too close to the weight limit, it probably won't work well, and this was literally the only arm I could find that was rated to support my monster! Not only does it hold the weight of my Cintiq beautifully, the motion is smooth and effortless, only a very slight wobble, and I can lean on it pretty hard without it going down. It's a little tricky sometimes to get the wrench-key into the right spot for adjusting the tension, and every person will prefer something a little different - but once you get the hang of it it's a no brainer. Installation itself was easy and instructions were clear. The only difficulty was lifting my Cintiq onto the arm once it's all assembled, because the dumb thing is so darn heavy it would have been nice to have a second pair of hands... but that's not the arm's fault! Ergotron is the standard in the entertainment/arts industry for a reason. I'm an artist, so aesthetics matter, and it has to function all day long every day. I COULD NOT be more pleased. I'm an extremely tactile and picky person I got the polished aluminum one and I have to say, it's actually beautiful. It doesn't have that "ergonomic tech" look that a lot of other "ergo" products have, which I think is pretty tacky and wanna-be futuristic. This thing though... this is a beautiful and sturdy piece of engineering and it performs it's function to perfection. THANK YOU ERGOTRON. My desk is 30" deep and it reaches well beyond the edge from the back, but I have it mounted to one side and it works just fine there too. This is such a massive improvement over the piece of crap stand that the last few models of Cintiqs have come with (the one that only has two positions to choose from, is difficult to adjust, and weighs a freaking ton), it's just night and day. It's rare that I am so dang chuffed over a purchase that I feel COMPELLED to review it, but this one dear god was completely worth it. Improved my workspace 1000% times over and I'm pleased every time I see it and grateful every time I use it! What a spectacular piece of equipment!!!!

UPDATED REVIEW: I purchased the Ergotron HX 6 months ago and discovered that the tilter lacked the lift strength to hold up the monitor. I opened a ticket with their support team, and a few months later they worked with me on getting a replacement tilter. It works great! The new tilter is plenty strong for my particularly heavy monitor. They also fixed an issue with the instructions, where the instructions didn't tell you which way to tighten a particular screw to increase/decrease tilter strength. So, kudos to them. I've been very impressed by the level of the support from Ergotron here. They constantly kept in touch with me about my issue. I am definitely a Ergotron fan at this point. I will say that my original review's criticism of the mounting process is STILL TRUE. That is one area Ergotron should iterate on. Anyway, if you're looking for a great heavy duty monitor arm, you've found it! I'll keep the old review here for posterity. OLD REVIEW: Titled: "It doesn't hold up" The HX lacks the tilt lift strength to hold up up my monitor, an Odyssey G9, which is 14 Kg and well within specifications. It is essentially stuck in a 5 degree downward angle, unless I prop it up. Other issues: - The instructions don't say which way to turn the included T-wrench to increase or decrease the tilt lift strength! Incredible. (This is noted on all the other adjustments in the instructions, besides this one.) You'll either have to look up external resources to find out, or just experiment (possibly in vain, like me!) - This was the most painful mounting of my life. Like other mount systems, you install an adapter on the back of your monitor, and then you mount your adapter-plus-monitor onto the stand. Usually the port to mount the adapter has an ergonomic shape which makes mounting a breeze. But not this one. The target port on the stand is very small and hard to mount onto. Plus you'll either need to mount the monitor holding it at a 70 degree angle, or you'll have to press down on the spring mechanism to hold it down while mounting it. This requires a lot of hands, and difficult to do solo, especially while holding a 14kg monitor. It took me two hours to assemble and mount my monitor, and then it doesn't even hold up the monitor. I opened up a chat with support, which to their credit they answered up right away. However, they weren't able to commit right there to sending me a new replacement adapter (it's labeled "A1" in the instructions). They said they'll talk to their tech team and mail me back. If they send me a nice replacement I may adjust my review. Otherwise I'll just send the whole thing back to amazon and try again with a different mount.

The monitor arm’s clamp is not big enough for my desk. Cool monitor arm and I’m glad that it was a great solution for so many people but for me (so far) it’s bust. The clamp doesn’t open up wide enough to slide past the back plate on my desk. Ergotron provides another attachment option but that requires drilling a hole into my desk. Not sure I’m going to take that route. I like the idea of attaching the monitor arm via clamp because I can unclamp and reposition it without any sort of permanent damage. There’s no undrilling a hole once I’ve put one in/through my desk’s surface so mounting the monitor arm using that method…unappealing. My hopes for this device were not exactly sky-high. I just wanted to clamp it to my desk. In that simple matter it failed. Attempts to contact Ergotron on a Sunday were unsuccessful. I thought I could get in touch with someone since the phone number at store.ergotron.com boasted customers could call store support 24/7. I guess that was not totally incorrect. I can call them 24/7, it's just not guaranteed that someone will answer. That’s where the claim fell short. No doubt Ergotron has some excuse in the chamber to explain this away. Dialing the number on the installation instructions also took me to a recorded response. Both recordings supplied me with business hours (drastically reduced from the 24/7 claim found on store.ergotron.com) that I probably could’ve deduced on my own. So far this monitor arm is a waste of time, money and effort. There’s a good chance the thing will be going back. I’m going to reach out to Ergotron again. They seem to be a highly-revered company and I’m sure that some clever individual in their employ suggested making a clamp that opens up wider than the one that was packed in with the arm. And if that happened I’m going to suppose that some similarly-clever person put one such accessory into production. I did check for one on the website but found nothing. Its completely possible that I didn’t check in the right spot. I hope that’s the case. Looking back, I should’ve dug deeper for specs on the monitor arm but who knew I had such an exotic piece of office furniture? I just thought I had a desk. This review will be updated if a working solution for the arm can be achieved or if the over-hyped device is returned. 8.1.20 I returned the arm. Ergotron attempted to provide me with a solution. It failed. They came up with a way to widen the amount the clamp could open (up to 94mm) but it still wasn't enough to open up around the back of my desk (116mm). Amazon took the arm back (thanks Amazon because that dud wasn't cheap) and refunded the purchase price. One thing, the response from Ergotron was a bit presumptuous. It said that "Without something custom the only option would be to use what I had." Huh? Exactly what "custom" solution would I happen to have up my sleeve? My "custom" solution was to eschew the factory-supplied stand in favor of the Ergotron monitor arm. I didn't know I needed a second custom solution to get the first one off the ground. I did a cursory search for some kind of adapter but came up empty. That's enough. I need a monitor arm, not a weekend side project to last for the remainder of the year. I wish I could offer some comments about the performance of the arm once a monitor has been attached but I couldn't even get the thing mounted to my desk. I'm going to explore non-Ergotron-related options.
