Love this thing
I originally purchased a cheaper brand mount for my G9 and it did not go well. The install and removal were nothing short of a nightmare. I did not want to go through that experience again, so I decided to spend quite a bit more for the mount that came highly recommended. As soon as you pick this thing up, you can feel the difference in quality. The weight, mounting pieces, and the pivot made me feel like I wouldn't have anything to worry about trusting it with my monitor. Install was a bit tricky, but not because of the mount, but the desk I was using. It was narrow and the top is very thin. I originally tried drilling a hole due to my desk having a bar blocking the place where the clamp goes, but it stuck way too far out. I decided to buy a 2x4, cut it to size and making a channel that goes over the bar. This did the trick and created a great platform to clamp onto. The rest of the process was cake. The arm needed an adjustment to support the weight but the pivot, the pivot was perfect right out the box. Raising and lowering the monitor kept it level and never once did it drop. I wish this was a little cheaper but you get what you pay for. My only gripes would be with cable management and not being able to turn the arm more than 90 degrees left or right from the center position. This is just me nitpicking though because there really isn't much else to complain about.

I'm a believer. Worth the premium over cheaper offerings.
I've always used monitor arms and have been content with cheap "no name" brands (Monoprice, Vivo, Wali, etc.) Recently I purchased a 49" Neo G9. Technically, it does not weigh *that* much (~26 lbs without stand), so I figured I'd give a Vivo premium a try. Although that arm claimed to support 30+ lbs and 49" monitors, it was barely useable. You couldn't make any real adjustments and the arm barely held the monitor up. It was floppy with slop everywhere. I purchased this Ergotron to replace it. The second I opened the box and started pulling parts out, the difference was night and day. Each Ergotron part feels solid. They are weighty and appear well designed. The most important part, to me, is the tilt mechanism. It uses a spring mechanism which is far superior to competitors rubber bushing tensioners. It handles the 49" Neo G9 with ease: it will hold it steady while also allowing easy direction of tilt. Assembly was remarkably easy...easier than competitors. The primary difference is the way the monitor mounts to the arm. Most competitors use a plate that slides into a groove and "locks" in place with a detent. This introduces flex which makes it feel less secure and makes it harder to adjust the monitor properly. In contrast, the Ergotron uses a vastly superior design with a solid metal connector that slots *and then bolts* together. It is both easy to connect (even with one person) and sturdier than the other design. I was hesitant to spend so much on a monitor arm, but it is well worth the 250% price premium here. While I think for sub 34" monitors the competitors can offer a good value, for large monitors, this can't be beat.

The best monitor arm on the market for 49" curved ultrawide monitors
I just installed the Ergotron HX Desk Monitor Arm with HD Pivot and couldn't be happier. The thing is an absolute beast in terms of heavy duty build quality. It holds up my 33 lb. Samsung 49" super ultrawide monitor with ease. Installing the arm to the back of the monitor and securing it to the back left-hand corner of my desk was super straightforward. My monitor is now at eye level and the extra desk space is fantastic. The price is steep, but it's totally worth it. My only regret is not getting this monitor arm sooner.

Everything I could ask for
1) This IS able to rotate 360 degrees at the base! I just want to put that first because of the huge amount of misinformation in the comments. There is a set screw you need to back off at the base. It's very easy to do and the only reason it exists is to prevent it from being knocked into a wall if the desk is flush. The other complaint I see is the fact the monitor rotates from landscape to portrait too easily. While this is true, there is a set screw that can be placed to prevent it from rotating in that way at all, which I'm assuming is 99% of people's preference, strange it isn't installed by default. 2) The quality of this thing is astounding. I was truly shocked as I removed it from the packaging. Is it $400 worth of quality? Hard to say. I know I'd have purchased it much sooner if it was $250 instead but I can't see how the material and built could be any better. They definitely don't cut corners. 3) This was very easy to set up. You WILL need to remove the monitor to make any adjustments to location or if you don't get the pieces seated properly, and obviously that is a task for 2 people. It can be a little unnerving but that's just the nature of dealing with something the size of a G9 or similar. I would buy this again, and I wouldn't wait as long as I did the first time.

Very good, but also very expensive and not as adjustable as I'd hoped
To begin with, this is obviously a very well built product with quality parts, as it would have to be to support a monitor like the G9 (as I'm using). Further, there's very little wiggle and it keeps its position very well. So kudos, it does the main job well. But... the price is exorbitant. A basic monitor arm costs literally one tenth the price, there's absolutely no way this requires ten times the materials or engineering, you are definitely paying for both the brand name and the fact that no one else (that I know of) makes a stand with this weight capacity. Supply and demand, I guess, but the stand that comes with the G9 is so excellent I really question if I made the right choice. Assembly is pretty straightforward, though if you have the G9 you will definitely want a second pair of hands actually lift it onto the mount. Adjustment in all directions works well enough but it really wants to move in some ways more than others. For example, it rotates (the one adjustment I never want to make) far too easily so I'm always leveling back out after moving it. And of the three main pivots, the middle one moves much more easily than the other two so actually moving it backwards and forwards it is a matter of swinging it side to side until you can get each pivot to move the way you want. It takes a good 30-60 seconds of wiggling just to push it back. Maybe this is unavoidable due to the monitor weight, but don't think this is something you can just adjust on a whim. Also, the depth adjustment is surprisingly short. I measured a measly 18cm of range - they advertise more, but that requires pushing it off to one side which isn't going to be a good option for most people. This is partly because the main pivot where it meets the desk is limited to 180 degrees from left to right, not ~360 as you might expect. It's puzzling because you can rotate it the full 360 by removing the set screw and it seems to operate just fine, but obviously that's risky to do without knowing why they limited it in the first place. If someone from Ergotron reads this, I'd love to know why it's limited and how dangerous it is to use without the screw. Finally, the cable management is, as always from Ergotron, hugely disappointing. I can't believe they still don't make this a priority. There's ways they route cables: first, two little velcro strips that are ugly, hard to close neatly, and tend to come out and are a huge headache to get back in. Worse, they don't even hide the cables! It's the cheapest, laziest solution imaginable. The other is a cavity on the rear arm that's covered by a plastic sheath. This at least looks nice once they're tucked in, though doing so is a pain and getting the plastic part on an off is rather tricky. I don't exaggerate when I say I've bought sub-$50 monitor arms with more elegant and thoughtful cable management solutions. Figure it out, Ergotron! I'm paying you way too much for this malarky!

High quality matetials and does rhe job very well
Excellent quality (apart from the *very* cheap plastic cable containment door under the arm). Easy to assemble and, after adjusting the pressure on the lift (upwards), my LG 49" was held without issue. Mine is about 25ish pounds and I suspect this arm can hold much more as the literature suggests. There is no bound in my set up - I am a programmer so there is lots of rapid typing. It's definitely pricey but it does exactly what it promises to do. And it does it well and with heavy, well made, quality parts.

Done with knockoffs
I hated, hated hated hated spending $400 on a monitor arm but I had a Vivo and before that an even cheaper one and my Vivos tilt mechanism broke and my 49" Samsung CHG9 came crashing down. So I decide to finally try to ergotron becaues I was sick of the cheap arms. It's worth it. It's a hard pill to swallow and I still think it's shockingly expensive but the thing is a TANK. I have to mount my 49" to the table myself with no help from another person and it was a NIGHTMARE with my VIVO but I had a really simple time with this one. You still need some muscle to hold the monitor up while you're sliding it around the desk but I always felt like my Vivo was going to get me killed. This was so sturdy I had no problems unscrewing it from the table and sliding it over a few feet while it was all mounted. Cheers great work Ergotron I'm a believer. Great quality. Heavy af.

Works great with the Samsung G9
I was hesitant about spending so much on a monitor arm. With the curvature, weight, and investment in the G9, I knew that I did not want to risk getting an arm that would not be able to support the monitor. The amount of adjustment on this arm is great for my use, and having the options for both grommet mounting and clamp mounting is a plus that should allow this arm to be useful into the future regardless of what desk and monitor I use. It did take adjusting the height piston a good amount for the arm to hold the monitor where I wanted it, but once I completed the adjustments, it has held true ever since. It was easy to attach to the desk and attach the monitor. Although it may be possible for one person to install the monitor on the arm, I would highly recommend using at least two people to install a large monitor on the arm to assist in setting it in place and adjusting the pistons. The company I work for uses some Ergotron products in the office, therefore I believed it would be worth the investment for my home setup, and I have not been disappointed so far.

Potęga i cudowne wykonanie
Nic lepszego nie znajdziecie. Jakość wykonania top. Każdy, nawet najmniejszy element ramienia ma sporą wagę i ma bardzo porządne spawy. Z łatwością utrzymuje mi (i ma jeszcze dużu zapasu) Samsung Odyssey G9 Oled 49". Polecam.

The build quality of the Ergotron HX is outstanding. It feels incredibly sturdy and well-constructed, giving me confidence that my expensive monitor is safe. The adjustable arm allows for a wide range of motion, making it easy to position the screen exactly how I want it.

Installation was straightforward, with clear instructions and all the necessary hardware included. The sleek design also adds a modern touch to my setup, and the cable management system helps keep everything tidy and organized. Overall, the Ergotron HX Mounting Kit is a fantastic investment. It combines durability, flexibility, and style, making it the perfect choice for anyone with a large monitor. Highly recommended for a top-notch mounting solution!

ok
Le support pour écran de 49 pouces est excellent. Bien que le prix soit un peu plus élevé par rapport à d'autres marques, il offre une réelle prise en charge pour les écrans XXL. La construction est de qualité et l'installation est facile. Il faut toutefois compter sur l'aide d'un autre personne pour fixer l'écran (étape finale) et régler la précharge afin qu'il ne bouge pas du tout. J'ai utilisé ce support depuis plusieurs semaines avec mon écran Samsung et je suis satisfait de sa stabilité et facilité d'utilisation dans tous les axes. Le grand avantage est que cela libère beaucoup d'espace sur le bureau, car le pied de mon écran était imposant.
