## Description

desertcart.com: Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – Polished Aluminum : Electronics

Review: You get what you pay for, but shop before you buy - I research most anything that is a specialty item and/or over $100, I believe in getting my money's worth but also hate getting sold on a cheap product. I searched all over the internet for a monitor stand that would offer some flexibility in what it could offer and this is the one I settled on. To each their own. My thoughts so far; The pros: strong arms rated for heavier monitors, a laptop option, adjustable height arms as well as the support base gives multiple ways to move the arms independently from each other and even swap side to side if I so choose (some stands the arms will conflict with one another), I liked the polished look contrast against the black, kinda classy. The base is solid with a "through" mount option, and the routing method for cables was about as good as any other stand. The laptop stand partially holds a computer by velcro which was very secure even with smaller pieces; also some rubber padding strips provided (both are 3M and good quality). The cons: the price is somewhat expensive, and the joints are incredibly stiff, at least to start. So, basically I have been very impressed with the item. It seems very well made, I like the look of it, and it is solid, the laptop stand is much more secure than I ever would have guessed and have been tearing my laptop off but better than there being a chance of it falling. Also, it is natural to grab the monitor, or in this case the laptop case, to use as leverage while adjusting the arms. I have a 29" monitor to go on one arm and it will likely be able to handle a bigger model in the future. But from the factory the joints are LOCKED tight. This shows the quality of the build, but frustrating at same time. The item came very well packaged, all the pieces set in their place in the box. The smaller individual pieces came in sealed, consecutively attached bags (for the most part, some stand alone items) overall very organized. This is a really nice item, and although it takes some getting used to maneuvering the "limbs", it really makes the desk seem more spacious once the clutter of moving is cleaned up. The joints are pretty tight at first and may get easier with more use, but as-is and considering the weight they need to handle it is not a real issue. Completely recommend this item.
Review: Extremely sturdy and fulfills a fairly uncommon niche - 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.

## Questions & Answers

**Q: Can this hold 2 27"  monitors.**
A: Yes, so long as they're not ultra wides or wider than usual. I have a 32" and a 27" on mine, the 32" puts it too close to wrap around me so I had to purchase the Ergotron LX extension to help it out. I imagine 2x27" should fit fine. These monitors are right around 20 lbs and it holds them up very stiffly, but that's adjustable.

**Q: Can you stack x2 34 inch 13.4 lbs lg 34uc89g ultrawide monitors on the ergotron lx dual stacking arm?**
A: Sadly the issue is not so much the weight, it's the height.... or lack thereof.  If you have newer monitor that isn't crazy heavy, you will be fine with double stacking 34 inch monitors. I have 4 of these arms, on with the tall pole and have mounted all a 24 pound monitor plus a second 18 pounder on the same mount with absolutely no hint of an issue with weight...in any way. The problem is that the 13 inch tall pole just isn't tall enough to give you the height you need for the second monitor.  Even if you practically set the lower monitor on the damn desk you still barely have room to squeeze a second monitor on top.   I have no idea why Ergotron has not realized that monitors are getting bigger and that they need to raise the height of the pole in order to allow people to mount 2 large screens.  I am looking into having a machine shop make me a 20" tall pole.  I have done a fair bit of research online and others have said that the cost to have this pole manufactured at a machine shop is around $60.  Sad that we have to resort to this because the company that makes the best monitor arms out there can't manage to keep up with the times and offer a product that will work.       It's also annoying that Ergotron will not sell the poles separately as spare parts.  They sell most all the other parts necessary to piece together one of their monitor arms, but not the poles.  So while they may soon be making arm options with taller poles, and despite having already bought 4 of their arms, they won't sell me just the pole so that I can change out the pole... they want me to buy a whole new double arm unit for roughly $300.  What a joke.

**Q: Will it support x 2 38 inch dell 38” wide screen ips monitors stacked on top of each other?**
A: Will it support x 3 38 inch monitors while using the "LX ARM Extension & Collar KIT (98-130-216)" attachment? Two monitors side-by-side and one on top using the Ergotron extension?

**Q: Does the mount only attach to a desk or can it be attached to a wall?**
A: Desk only - The base requires a horizontal surface and the rest of the mount requires a vertical pole.

### ⭐⭐⭐⭐⭐ hard to believe how beefy it is for the price
*by J***H on February 10, 2014*

can't imagine any other arm being as beefy, and not for this cheap. the stacking works great, with 22" monitors. The pole is completely solid, though through all the joints in the arms there is a bit of play. Basically if you bump into the monitors they will wiggle back and forth until they settle, however the movement is small and if you aren't bumping into them they don't move at all. The mount works well. Downsides: arms are beefy and take up some space, ESPECIALLY factoring in the joint at the monitor. Basically make sure you have some space because the parts are soo damn big! I'm not sure but I get the impression that you could put a couple 27s on here or something heavy because this thing is a beast. i was shipped the version WITH the laptop stand, so you can use it with 2 monitors or a monitor and a laptop. the laptop stand is probably part of the reason the arms are so beefy. i will say that the human scale single monitor arm that I have is at least ten times more svelt and sleek, but it's clearly not as strong / beefy. If you need something that looks really nice this ergotron isn't it...though it still looks pretty good. just the wires don't disspear as much, and the black and silver look just isn't awesome. also, the friction adjustments on the human scale seem cheap compared to the adjustments here on the ergotron. they both do the same thing, but for the most part i like the ergotron better. that said, if I didn't need stacking and didn't care about cost, and had a desk where the arms were visible (no wall) i'd buy a couple human scales. those conditions not withstanding (i.e. most situations) the ergotron is the one! All in all, this has got to be the best value in monitor arms out there. you don't have to stack with it, and you dont' have to use the laptop mount, but you WILL be happy with the strength and obvious quality, and you'll be thinking "how could this be so cheap?"
