For the longest time I had been using the regular desk stand with my Samsung 57" Ultra-wide monitor and then I started revamping the gaming space and wanted to free up valuable desk real estate. I've previously used the Ergotron monitor arms for my monitors and they work very well, but I wasn't in the mood to spend 400+ for a monitor arm. I came across this monitor arm that got decent reviews online so I decided to give it a shot. It's perfect for my needs. It holds the 57" monitor really well. You will need to use the included VESA plate that came with the monitor to mount it correctly. The arm was very quick to build and (although not recommended) I was able to mount it without any assistance. The adjustability of the arm is decent although I don't plan on moving it around much. It has a built in cable management option which works very well at hiding the cables for a clean install. The item seems well-built and has a good weight to it to support the monitor. I would highly recommend it for anybody looking for a mount to hold a heavy duty monitor. Just make sure to follow the instructions with regards to dialing the tension. It includes the tool to do it and it's pretty straightforward to adjust.

Works great for my 57in Samsung G9 Monitor. Installation was easy, quality feels solid, and did not put much weight strain on my desk. The one thing that could be included in the instructions is tightening/loosing the tilt head to make the mounted monitor more level. It mentions loosening/tightening the tiny screw in the back of the tilt head, but doesn't mention doing the same for the two larger black bolts near it. I was not able to get the tilt correct until adjusting those two. Recommend doing those prior to placing mount on the head, otherwise you'll either need an extra person or use some strength to get it to the right tilt while tightening the bolts again. But otherwise great product. Monitor does not "jiggle" and stays in place perfectly. Good range of motion.

Great monitor mount. Held a G9 Odyssey OLED with no issues. There is no swivel support, but this is an excellent arm for the price. No sag and mounting it to the desk and arm is simple.

Super reliable, it is heave but sturdy, it gives you that feeling of security that your monitor won't fall off, I'm currently using a 49'' and I can rest assured that it won't go any where. On top of that the ability to hold more than one monitor is really desirable, really a space saver with a lot of cable management included in it. Something to notice is that this arm does not includes a vesa adapter to connect with the Samsung Odyssey G9 for example, that will have to be purchased separated

Super heavy duty arm would highly recommend and the finish is beautifull, will buy another in the near future. Just make sure you desk is not to wobbly or to thin to prevent any sagging, the arm along with the heavy monitor.I built a support in the wall because the arm is heavy and my monitor screen is as well.

I bought the ULTRARM Heavy Duty Monitor Arm (MA20P-S) specifically to mount an LG 45GX950A-B 45-inch Ultragear 5K2K (5120×2160) OLED curved ultrawide, and I also cross-shopped/installed two other “heavy duty” options: the VIVO STAND-GT57 and the Ergotron HX HD. Why I kept the ULTRARM The biggest differentiator is expandability: the ULTRARM base can be used to add up to two additional displays later (with additional arms). That modular approach was exactly what I wanted for my desk setup. The arm itself is solid and stable, and it has enough articulation to position a large ultrawide properly. Installation & daily use Setup was straightforward and didn’t feel sketchy even with a big, expensive OLED on the end of it. Once adjusted, it holds position well. Swivel and rotation are tool-free, which makes day-to-day positioning easy. Cable management (good idea, tight execution) Cable routing works, but the routing guides could be deeper. With 3 HDMI cables + power + a couple USB cables, it was a very tight fit. It’s doable, just expect a snug pack if you’re running multiple thick cables. The one real downside: tilt adjustment Tilt tension is controlled by a large set screw, so if you want to change tilt you’ll need an Allen wrench. Not a huge deal for me since I rarely adjust tilt once it’s set, but it’s worth calling out—especially compared to premium arms that allow tool-free tilt changes. Quick comparison to the alternatives I tried Ergotron HX HD: Beautiful build quality, but I was very disappointed with the limited articulation (my unit wouldn’t go beyond about ±90°), which made it impossible to push the monitor back to the rear edge of my desk. Also extremely expensive for the limitations. The one thing it does well: tilt/swivel/rotation are easy to adjust without tools. VIVO STAND-GT57: Surprisingly strong, stable, and a good value. Packaging isn’t “premium,” but the arm is. If you only need one heavy ultrawide, the VIVO is honestly a great choice. Bottom line If you want a single-monitor setup, the VIVO may be the better overall pick. But if you want a heavy-duty arm that can grow into a multi-monitor setup, the ULTRARM is the winner—and that’s why I kept it. Rating: 4/5 (would be 5/5 with deeper cable channels and tool-free tilt adjustment).

My 57 was a little too heavy but my 34 worked perfectly.

Pros: Works well for 2x 49" on top of each other. Plus a laptop / additional monitor that's vertical. It will hold a 57" samsung, but due to the weight and mount, your desk might not support this mount. I have a corner desk that's about an inch thick and I had to add 2 2x4's to this thing. one below, one above, to sandwich this mount. It could not hold the 57" plus an additional monitor because the 57" is so heavy. I have the 57" on it's own factory provided desk mount. I have the 49" on top of the 57 with this mount + an additional arm for a monitor/laptop off to the side. I'm using the arm for my work laptop so it's off the desk. I am a little disappointed in the setup. I wish the mount was a little bigger (or offered a fatter mount). I wish the mount pole was taller. I can barely get the 49" to sit above the 57". Even with the 2x4 between the desk and the mount. The arms themselves are very impressive. 5/5 on the arms. 3/5 on the mounting system itself (base + pole height). Pole is sturdy. No issues there. Needs an optional bigger / heavy duty mount and a taller pole. If you want to get this for 2x 57" samsung's ... look elsewhere or custom make your own mounting system and use these arms. The arms are 5/5. no issues there! The mounting system is meh.
