ULTRARM Heavy Duty Monitor Arm for Ultrawide Monitors up to 57" and 44 lbs, Single Desk Stand, Pneumatic Height Adjustable, Modular Extension Arms - Max VESA 100x100, Black, MA20P-S

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.

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.

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

This seems like an excellent product. It’s strong enough to easily handle my 42-pound ultrawide monitor, and all the parts seem to be of sturdy construction while still looking somewhat sleek. After tinkering for a minute or so with the tension settings, it is very easy to adjust the monitor’s position. I particularly like that the arm connects to your desk with two separate clamps rather than just one, which seems to provide a very stable attachment. I’m not currently using this feature, but you can apparently attach up to three arms to the base if you have a multiple monitor situation (but not to exceed the stated 50-pound total weight limit).

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).

Well, this big boy holds my 49 LG like a champ. I even have it without the middle section since I am not using it to rotate or changing positions. I only grab this mount to replace the oem legs of the monitor that takes too much space on my desk. It is really sturdy and very stable. It was very easy to install and save me lots of space. Great deal on the price since all other brands for this 49+ are over $280. Took me like a week of searching and reviewing other brands but finally I've got what I was looking for.

This mount's tilt adjustment is so bad and caused so much plastic stress on my monitor that it eventually broke the VESA bracket on my display chassis and damaged the power supply behind it. My monitor is now dead. Skip these arms if you have a heavy ultrawide monitor. Go with an equivalent Ergotron mount. The tilt adjustment does not adjust easily at all and does not adequately hold heavy monitors in place. They will always tilt forward no matter how much torque you put on the adjustment bolts. Even the significantly cheaper Vivo branded display mounts have better adjustment points. UltraArm quite nearly has an excellent product, but this design oversight just completely ruins it. And now I have a broken monitor to show for it Avoid this mount and the extensions. Go with Vivo or Ergotron instead, whatever is easier on your budget. This mount, in its current form, will eventually destroy your display.
