The best monitor arm I could find!

Review by CS

Loving the LX arm I got, it actually supports my giant Acer XB321HK monitor that NO OTHER ARM can support. Not gonna lie this thing is a beast at a whopping 32" but the arm actually holds in place once you tighten it down.

One gripe, because nothing is perfect, the arm does shake when anything bumps the desk . Fixed this issue by buying another 27" monitor to support the 32" one. Beware if you are only supporting one large monitor, it does shake when bumped or spiritedly typing.

Overall, 4.5 stars because the monitor arm isn't as stable as I would like it. That being said, this is the most premium monitor arm on the market, and I will be purchasing my 2nd Ergotron arm soon. 100% would recommend.

Great Products!

Review by Casey

I have started outfitting my whole office with Ergotron monitor arms. Both the HX and LX are great products, but you can't beat the price of the LX!

Very Sturdy

Review by Cory

I debated buying this arm or a much cheaper arm from a different online retailer. I've always been a fan of buying the more sturdy option for peace of mind and longevity, and I'm very happy with my decision. Although the price definitely isn't cheap, the arm feels very sturdy and I'm sure it will last quite a long time and be solid while doing it.

Very Sturdy

Review by Cory

I debated between buying a $30 monitor arm on Amazon and this arm, and, although I never bought one of the cheap monitor arms and therefore won't be able to make a direct comparison, I doubt they're anywhere near as sturdy as this one. I've always been a fan of buying the long lasting option even at a higher price point just for peace of mind, and this arm definitely exceeds my expectations!

Top Quality!

Review by TSW

Personally, I like to get things right & don't mind paying a little more for ease of use, comfort, functionality, and durability. This is exactly what I'm experiencing with Ergotron! From the very beginning, the product selection process and ordering from the Internet site to the prompt shipping and delivery to implementing the excellent products, my experience has been fantastic. Ergotron is a professional company offering quality products and it's easy to confirm. For my personal home office, using the monitor arms and an extra arm for the notebook computer tray - it's only been a few days since install, but I'm a completely satisfied customer & I'm sure you will be too. Don't mess around with other options, you'll be glad you chose Ergotron to make your life and productivity better!

Best, most premium monitor mount

Review by Brian

Out of the box, this monitor arm has very premium feel. It's heavy and sturdy enough to handle monitors much heavier than mine. I have a BenQ 24 inch and it handles it very well. This mount allows me to de-clutter my workspace even more for minimalist appearance. I have a standing desk that carries slightest wobble to the monitor during heavy typing but it isn't a deal breaker. I plan on getting a laptop mount to experiment with dual display set up. My only wish is that I had thought of dual arm mount sooner.

Best-in-class Monitor Arm

Review by Henry

After doing some research and talking to some folks out there, Ergotron was highly recommended as the best monitor arm. Fits well with my 34" ultra-wide monitor!

Buy "tall" version for a standing desk unless you're 5" (152cm) or less

Review by buy_the_tall_pole

I'm not tall. I'm 5'7" on an optimistic day. I bought this to use with a standing desk. Seeing options between a "tall" pole version and this "normal" version I thought "no way I'd need the tall size. I'm in the 25th percentile for height among U.S. adult men. I must be the regular size." I read the descriptions of the product and nothing indicated otherwise. Turns out I'm wrong and according to Ergotron I'm a towering giant in need of a tall pole. While this crafty attempt to boost my ego is appreciated (I need all the boosts I can get...especially when it comes to reaching things on high shelves), the misleading labels and marketing copy around this product sucks. Returning products and/or paying more for "tall" features that should be "normal" features is aggravating. Hopefully, you're not like me. Either you're actually tall and wouldn't think twice about buying a product specifically for your kind or you're short and learn from my mistakes. Otherwise, the product is just fine. Shipped on time, delivered in good condition, easy-enough installation, seems to do what it says on the label, supports my 27" monitor right around chin-height no problem.

Trust It

Review by Aaron

I wanted to put large monitors on both sides of my main monitor. This clamps onto my desk holds them perfectly when I want them moved I just pull on them they're going to position I never have to worry about it. That's exactly what I wanted I wanted sturdy arms that did their job that I never had to worry about. Don't skimp out on the arms. Just get these.

Well-engineered, solid support

Review by tdog

My arm holds a Dell 27" monitor. The mount was very easy to install. It is very flexible, and the monitor stays exactly where I need it. Attractive too.

Very satisfied

Review by Rider

Took a little adjusting, and the directions aren't real clear in a couple of perspectives of what direction actually adds tension v. release tension.

Amazing. No regrets.

Review by Cattacus

Some people say that a certain large online retailer that shares a name with a river sells a perfectly comparable monitor arm to this Ergotron.

They are wrong. Or they don’t have a large enough monitor.

This supports my 32” LG 32UD99-W perfectly, with only minimal tuning required whereas the previous arms I bought all failed spectacularly. This arm is finished superbly, high-quality, and solid. Everything functions as promised. Zero complaints here. I will be buying more Ergotron arms in the future without a doubt.
