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. 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. ## Features - Broad compatibility: Fits two screens up to 24 inches diagonal and 7 to 20 pounds each; compatible with VESA patterns 75x75mm and 100x100mm - Designed for workstation flexibility: Includes two arms, two extensions, 13-inch pole, two pole collars, base, two-piece desk clamp for surface edges 0.63 to 2.6 inches thick; grommet mount available (98-035) as a separate accessory - Large range of motion: Offers full monitor movement with 13 inches of lift, rising 22.6 inches from the desktop; delivers 25.6 inches of extension; personalize your view with 360 degrees of rotation and 75 degrees of tilt - Stable and functional: Monitors stay secure, stacking one over the other or positioning side by side; each arm lifts, extends and rotates for the best ergonomic view; arms fold out of the way to reclaim space for other desktop tasks; support a laptop instead of a monitor with separate accessory Notebook Tray (50-193-200) - Built to last: Extensive quality testing ensures your displays stay stable and secure; Ergotron products set the standard for quality with a 10-year warranty and expert technical support ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FW15UM4 | | Best Sellers Rank | #267 in Computer Monitor Arms | | Brand | Ergotron | | Built-In Media | monitor arm | | Color | White | | Compatible Devices | Monitor | | Customer Reviews | 4.6 out of 5 stars 1,535 Reviews | | EU Spare Part Availability Duration | 10 Years | | Enclosure Material | Metal | | Global Trade Identification Number | 00698833058413 | | Item Type Name | Ergotron 45-492-216 LX Dual Stacking Arm Aluminium Durable Steel Mounting Kit for 2 LCD Displays, Desktop Stand, Screen Size: Up to 24", White | | Item Weight | 0.9 Kilograms | | Manufacturer | Ergotron | | Material | Metal | | Maximum Tilt Angle | 75 Degrees | | Maximum-Supported Screen Size | 24 Inches | | Mfr Part Number | 45-492-216 | | Minimum-Supported Screen Size | 1 Inches | | Model Number | 45-492-216 | | Mounting Type | Tabletop Mount | | Movement Type | Articulating | | UPC | 698833058413 | | Unit Count | 1.0 Count | | Warranty Description | 10 Years | ## Product Details - **Brand:** Ergotron - **Color:** White - **Compatible Devices:** Monitor - **EU Spare Part Availability Duration:** 10 Years - **Global Trade Identification Number:** 00698833058413 - **Material:** Metal - **Maximum Tilt Angle:** 75 Degrees - **Mounting Type:** Tabletop Mount - **Movement Type:** Articulating - **UPC:** 698833058413 ## Images ![Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – White - Image 1](https://m.media-amazon.com/images/I/717URLOBOdL.jpg) ![Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – White - Image 2](https://m.media-amazon.com/images/I/71ZonlZ6taL.jpg) ![Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – White - Image 3](https://m.media-amazon.com/images/I/81ZMLfvCVgL.jpg) ![Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – White - Image 4](https://m.media-amazon.com/images/I/71TOWx9IgcL.jpg) ![Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – White - Image 5](https://m.media-amazon.com/images/I/710Aistf3BL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Extremely sturdy and fulfills a fairly uncommon niche *by J***S on February 28, 2023* 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.

Completely recommend this item. ### ⭐⭐⭐⭐⭐ 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?" ## Frequently Bought Together - Ergotron – LX Vertical Stacking Dual Monitor Arm, VESA Desk Mount – for 2 Monitors Up to 24 Inches, 7 to 20 lbs Each – White - Ergotron – Notebook Tray – for Laptop, Notebook and Tablet Screens up to 17.3 Inches – Add-on for VESA Monitor Arms --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/32899697-ergotron-lx-vertical-stacking-dual-monitor-arm-vesa-desk-mount](https://www.desertcart.vu/products/32899697-ergotron-lx-vertical-stacking-dual-monitor-arm-vesa-desk-mount) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
