    • Extremely sturdy and fulfills a fairly uncommon niche
Color: Matte Black Size: 23 Inch Pole
Review Image by Joe Wells Joe Wells
Short version : _____________ Pros: - easy to assemble - very robust and sturdy, will hold up very well within guidelines - fairly decent free range of motion Cons: - dat price tag $$$$ - certain features like cable routing and swivel leave some very minor grievances LONG version : ______________ You don't have to read it all, but if you're already looking into buying this, there's a decent chance you are in a similar situation. If I was being nitpicky this would be a 4/5, but seeing as how there's really no other manufacturer that readily provides a solution to my problem it really is just the best I can get, from what I've seen. I upgraded from an LG 34UC89G-B 34" 21:9 to an Alienware AW3423DW 34" 21:9 and wanted to keep both monitors, with the new one on bottom and old on mounted on top. My old 2 arm mount was not going to be able to support this much weight as my other monitor was just a 27" 16:9 and it barely held those together. I didn't want to have to screw anything into my wall and I wasn't 100% sure on my desk space so I wanted free moving arms for orienting the monitors before finalizing where I want them to stay. Once I got this I was able to set my monitors up stacked on top of each other. While the bottom one isn't quite sitting as low as it can go, it's not far off. But the top monitor is just about using the mount's maximum capabilities in terms of being able to space these monitors apart while still leaving a tiny bit of room for adjustment. I have been able to pull my top monitor forward and rotate it portrait for documents and such though I have not done the same with the bottom monitor. ______________________________________________________ Overall actual use after setup: 9/10 The monitors themselves are not on the extreme end of heavy but they're not light. They both fall within the specifications of the mount. But where Ergotron excels with the LX is that it will actually support curved monitors up to that weight as well, as the curvature changes the center of balance of the overall monitor and puts more stress when extended out than your typical flat monitor. This is usually where you can see other people having issues with sag when approaching the upper limits of other mounting systems. These have not sagged at all since tightening down the screws and move with a fair bit of range, staying in place afterwards. However I do not extensively move my monitors around often and don't know how well it would hold up if you just kept moving them around constantly, though with the construction quality I'd wager it would be fine. One thing I was told from a friend who has the same mount: if your monitor is really bottom heavy for whatever reason and you decide to use it portrait style, the minor taps and thumps from your desk will cause it to try to rotate back to a horizontal position, skewed about 5-10 degrees. It's very minor and just takes a quick second to readjust but keep in mind that it may happen as 1 side is now far heavier than the other. ______________________________________________________ Setup process: 9/10 The setup itself was very easy. I saw other reviews having issues with it and maybe getting some help but if you follow the instructions provided, it is extremely easy, especially compared to setting up other mounts where you have to screw in the whole assembly to the monitor and take the entire piece and clamp it on your desk. You need to clamp down the base and bottom arm portions of the mount, then screw in the upper portions to the monitors BEFORE putting the rest of the mount together. The top arm portion falls right into the bottom and you just tighten the screw afterwards. If you can physically lift your monitor + 8 ounces or so, you will have no issues putting it together. One thing I will note: tightening the actual swivel head on the monitor so that the tension matches the weight of the monitor may be difficult if you are short since it adjusts from the top. WARNING: If your desk is particle board or something, I highly recommend buying reinforcement plates for the clamp. The clamp that the LX comes with is fairly sizeable but if you're going to be putting 50 lbs of pressure on 1 spot on your desk, it's best to not worry about the weight snapping your desk in half. If your desk isn't sturdy material: the arm mount will hold up, your desk will not. You're already splurging on this mount, don't cheap out and break your desk and potentially your monitors by skimping out on a $10 metal plate. If you don't want to go that route and don't care much about aesthetics, you can just use some wood. ______________________________________________________ Cable management: 5/10 Cable management looked like a mere afterthought. It's serviceable and hides the cables well enough but it's nothing to write home about. This feature has been better executed in cheaper models. ______________________________________________________ Range of motion: 8/10 Range of motion is better than most for sure. While it will still hold them in place, some positions and setups can be limited if you have enormous monitors. If you're using 2 24" monitors you will have zero issues, but the more you approach 40", even on 1 monitor, the options get more and more limited. ______________________________________________________ Final notes: I wish the pole was longer. That would solve a lot of issues people have had with mobility using large monitors. The arm mounts themselves hold up well, the fitting of large monitors just leaves something to be desired, especially out of something as expensive as this. ... show more

    • Much better than the "side by side" model.
Color: Matte Black Size: 13 Inch Pole
I bought this to mount a 27" monitor side-by-side with a macbook on a vesa-mounted laptop tray. I ended up buying this one because their "side by side" model was laughably short for me (5' 10"). This model works super well for me both while sitting & standing. Highly recommend this. I know it says it only supports 24" monitors, my guess is that's for vertical stacking. Multiple reviews state 2x 27" fit as long as they are within the weight requirements. I do find I have optimal range of motion by moving the desk ~3" away from the wall. I could see some users being frustrated by that but it doesn't bother me at all. ... show more

    • The Ferrari of Monitor Arms.
Color: Polished Aluminum Size: 23 Inch Pole
You need the ability to put 2 monitors stacked vertically up to 40 inches a piece? Practically nobody does, that’s just ridiculous. But that’s exactly why I know I can trust Ergotron to hold my 2X 24 inch Asus gaming monitors. They are truly over-engineered for greatness. I have zero complaints with ergotron aside from the high price tag but as the old saying goes, you get what you pay for. ... show more

    • Premium price, but worth it.
Color: Matte Black Size: 23 Inch Pole
Price is excessive for a monitor mount, but, it’s solid and I have zero concerns that it can hold two 32” stacked monitors, without issue. And that’s the key part, “without issue”. Plenty of monitor arms will work, but not all of them will last. And few will perform the same on day 1 and 1000. Lesser mounts will deteriorate, or simply fail by then. There’s no compromise with this mount. Everything about it is premium. Tip: the part where the the monitor attaches to the arm can rotate 360 degrees. This is handy in a stacked configuration because normally there is only a small amount of vertical tilt, which may not be enough for the top monitor. But if the monitor is rotated 180 degrees (upside down) you’ll have full range for vertical tilt. I like the top monitor the be upside down since the bezel is smaller in that setup. Or you can just attach the mounting plate upside down and keep the monitor in normal orientation but still benefi5 from the increased vertical tilt. No issues hold two 32” monitors, zero sag. But the monitors will wobble if mount or desk moves. Recommend a solid mounting surface. Overall, great mount. I’d purchase again. ... show more

    • Probably Over Priced
Color: Matte Black Size: 23 Inch Pole
Setup was a bit more then I expected, but the adjustability and expandability of the product I can understand why. Its extremely stable and works really well. I have 2 problems with it that prevent me from giving 5 stars. 1. I'm suing dual 27" monitors. The arms actually have to fold in towards eachother to get them to line up well, which means the "elbow" part of the arm pushes back past where the edge of the desk is and hits the wall. This means you have to move your desk a few inches out away from the wall to use with dual 27" monitors. I tried using only the 1 arm (without the bend) but it was too short. So Maybe dual 24" arms, or dual 32" arms would be more ideal... but I was sad that I had to move my desk out 6" to clear the arms on these mounts. 2. The price is just not right. You can get similar type setup for 1/20th of the cost, not sure why they charge so much for these. ... show more

    • Don't forget to adjust the spring tension
Color: Matte Black Size: 23 Inch Pole
As most other reviews indicate, these are expensive but also high quality. They're sturdy and the monitors move around. If you have two big monitors that you need to adjust independently, it's a great option. It won't be as ideal if you always want the two monitors to move locked together, since you'll need to adjust them separately. The instructions are only mediocre, and if you give up on them after getting it installed you may miss a really important point (I did at first): you can, and probably should, adjust the spring tension for the joints. So if you have a heavier monitor and the arm is bottoming out, you probably just need to tighten the springs. A wrench to do that comes with the kit. ... show more
