    Customers are satisfied with the performance of the flat screen display mount. They mention that it works well both while sitting and standing, the stand performs like a charm, and it works great using side by side configuration. The finish is quality and the system works smoothly. The laptop mount works really well for their 17" laptop, the included laptop tray adapter works very well, and the springs still work great. The other cable tie hangers work fairly well, while the dual large monitors work great for side by sides.

    "...Overall it's still attractive and functional, and should remain so for years to come." Read more

    "...The mount works well.Downsides: arms are beefy and take up some space, ESPECIALLY factoring in the joint at the monitor...." Read more

    "...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...." Read more

    "...This model works super well for me both while sitting & standing. Highly recommend this...." Read more

    46 customers mention41 positive5 negative

    Customers like the movement of the flat screen display mount. They say the monitors swivel easily, but don't move so easily that they turn by themselves. They appreciate the range of motion, saying it's great to freely move and adjust each monitor independently. The mount is extremely sturdy, with no movement after it''s put in place. Customers also mention that the arms are wonderful, allowing them to easily move them to whatever area works best.

    "...not sagged at all since tightening down the screws and move with a fair bit of range, staying in place afterwards...." Read more

    "...from both sides of the desk and in a variety of positions, easy movement is important: 8.5/10 on that score...." Read more

    "...The monitors swivel easily but do not move so easily that they turn by themselves...." Read more

    "...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...." Read more

    44 customers mention41 positive3 negative

    Customers like the appearance of the flat screen display mount. For example, they mention it has a good design, and is made of stainless steel. Some say it looks sharp and adds room on their desk.

    "...Overall it's still attractive and functional, and should remain so for years to come." Read more

    "...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..." Read more

    "...finish is a polished aluminum and it has black joints so the 2 tone looks really sharp...." Read more

    "...Pro:- sturdy- good designCon:- very expensive- can't hold more than 22 lbs monitor" Read more

    36 customers mention36 positive0 negative

    Customers are satisfied with the stability of the flat screen display mount. They mention that it holds the monitors well, the laptop stand attachment holds the mixing console perfectly, and it's strong enough to hold two 22-inch monitors. The arm mounts themselves hold up well, and can hold a considerable amount more weight than their Dell and Asus monitors, making it a good choice for professionals.

    "...The arm mounts themselves hold up well, the fitting of large monitors just leaves something to be desired, especially out of something as expensive..." Read more

    "...My thoughts so far;The pros: strong arms rated for heavier monitors, a laptop option, adjustable height arms as well as the support base..." Read more

    "...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”...." Read more

    "...They are holding three 24" Dell monitors without issue (and freeing up a lot of deskspace!)..." Read more

    68 customers mention40 positive28 negative

    Customers have mixed opinions about the value of the flat screen display mount. Some say that it is worth the price, while others say that they are very expensive and can't hold more than 22 lbs.

    "...All in all, this has got to be the best value in monitor arms out there...." Read more

    "...The cons: the price is somewhat expensive, and the joints are incredibly stiff, at least to start...." Read more

    "...It is worth the investment.I have a large Hon desk with a rectangular hole for wires on each side...." Read more

    "...Don't get me wrong, the side-by-side is excellent too, plus it is a little cheaper...." Read more

    62 customers mention40 positive22 negative

    Customers are mixed about the adjustability of the flat screen display mount. Some mention that it's extremely well balance and easy to adjust, with the range of motion exceeding. They say the monitors can be adjusted to proper ergonomic position. However, other customers say that the upper monitor has barely any downward tilt, the monitor is prone to tilting sideways, and the mounts make it difficult to use the vertically mounted monitor unless you lower the bottom.

    "...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..." Read more

    "...This Ergotron is built very strong. The arm tensions were easy to adjust and they are quite stable...." Read more

    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 motionCons:- dat price tag $$$$- certain features like cable routing and swivel leave some very minor grievancesLONG 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:9/10The 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:9/10The 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:5/10Cable 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:8/10Range 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.

    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.
