ErgotronUpgraded LX Pro Premium Monitor Arm, Single Monitor Desk Mount – fits Flat Curved Ultrawide Computer Monitors up to 34 Inches, 4 to 22 lbs, VESA 75x75mm or 100x100mm – Dark Grey

I've used a few cheap monitor arms in my life, and they are generally ok if you want to leave your monitor in one spot, but barely ok. This arm is expensive, but honestly for something you can keep using its worth the premium. I always thought a monitor arm is a monitor arm but this product changed my perception of that.This arm has very smooth motion, very easy to move it around and dial in the right setting you need for the situation. Once you got it positioned it is extremely sturdy and stays where you set it. You can continually adjust this thing with ease, no need to mess with tension screws or jank actions.It looks slick in matte black, which is a lot nicer than the plastic or shiny materials used in other mounts. Not really a big deal but its sometimes the small details.Installation was easier than any other arm i've installed. The parts are laid out properly and the way it goes together in parts is a lot more smooth than other designs. Its pretty much 3 lego pieces and you're done, the base is just a base so its not top heavy while you're trying to secure it to your desk. Monitor cant be nut locked in place so you have to remove the entire last segment to replace your screen, but that adds to the stability of the monitor as it doesn't shake at all.Having a screw to disable rotation is great for my OCD tendencies, you can get very slight rotation but getting it fully strait takes zero effort, no need for rulers.

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.

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.
