Ergotron – HX Premium Heavy Duty Monitor Arm, Single Monitor VESA Desk Mount – for Flat or Slight Curved Ultrawide Monitors Up to 49 inches, 20 to 42 lbs – Standard Pivot, Matte Black

This is undoubtedly one of the best monitor arms on the market. While it is on the pricier side, its exceptional build quality and heavy-duty design make it worth every penny. If you own a 49-inch monitor, I highly recommend choosing an Ergotron monitor arm over any other brand. I initially purchased a cheaper alternative but ended up returning it immediately. This is a classic case of "you get what you pay for," and the Ergotron arm is definitely worth the investment.**Pros:**- **Rock-solid design:** The arm's robust construction ensures your high-end monitor is securely supported.- **Ease of movement:** Adjusting and repositioning a 49-inch monitor is effortless, thanks to the arm's smooth operation.- **Easy installation:** The installation process is straightforward, but make sure you have all the necessary tools, especially a wrench for the monitor arm head. For a 49-inch monitor, having a second person to assist is helpful.- **Durability:** The arm shows no signs of wear or binding, even after extended use. Its overbuilt design provides confidence that your expensive monitor is safe.**Cons:**- **Cable management:** The arm's cable management system could use some improvement. However, this is a minor issue since you rarely need to access the back unless you're setting up an elaborate gaming rig.**Comparison and Recommendations:**- **Superior to other brands:** After reviewing various reports, the Ergotron stands out in terms of adjustability and stability, making it the top choice in its class.- **Versatile use:** I would exclusively recommend this arm for other types of monitors and specific use cases, such as dual-monitor setups or professional workstations. Despite being the most expensive option, it is well worth the investment due to its longevity and superior build quality.

I struggled to find an arm that would support my almost 33lb 4k 43" LG monitor. Sadly it is the most expensive but is among 2 that I found would work and the tolerances are DEFINITELY better for the Ergotron.Here is what I like:1: Stable - was concerned due to the drop in nature of Ergotron HX, but the monitor does not move after mounted2: Assembly - almost too easy; 32 lb monitor mounted solo VERY easily3: Ease of use - very very smooth4: Aesthetics - good looking; aluminum look only comes in white but matches the black items in the room I have well5: Quality - clearly built to last6: Warranty7: Company is known and has a US presenceHere is what I don't like:1: Price - it is expensiveThe cost is worth it in my opinion as the company has a US presence and a good warranty - also it is the only mount where my weight is in the middle of the road.My setup:----- ------------ -----| | | | | ||2K | | 4K | | 2K|| | | | | |----- ------------ -----Each of the 2k 27" monitors use the Ergotron LX.The 43" 4k monitor uses the Ergotron HX.

This monitor arm is extremely well made, durable and a lot more heavy then I thought it would be. So, overall the construction of the arm and it's design is very well made, heavy solid materials. It comes shipped in a great packaging, it's nice to see care in how much care went into packing. The assembly is relatively easy with just 3 parts that connect with a few screws to tighten. I'm using this arm with an LG 38" Ultra Wide monitor that I believe is about 15lbs in weight and it can easily move around without struggle on the arm.If you have a lighter monitor or a smaller sized one, you may have difficulty with the arm keeping a monitor in a low position. If the monitor is light weight < 12-13lbs it may want to lift up on it's own due to the heavy spring action. I had a smaller monitor on it while waiting for my ultra-wide and it was kind of comical. I added weight to the monitor to keep it down a bit.It supports VESA 100x100 and 200x200 on the mounting bracket. I feel like this is a good standard for newer monitors. The mount is sturdy and supports a really good range of movement tilting up and down as well as a full rotation on it's side. The arm movement is really reasonable in it's range of movement. I'm even able to drop my monitor down a bit lower than the clamp.The arm assembly also includes options to mount the arm with a desk clamp, or through a drilled hole. It has good options for mounting the arm as needed.I'm really satisfied with this purchase and can see this arm lasting a really long time - probably much longer than my new monitor. I highly recommend getting it.
