Great arm, full support, amazing cable management
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

Does exactly what I need it to do.
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.

Great arm, just be sure to adjust head prior to installing monitor
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.

Worth the price
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.

ULTRARM MA20P-S - for LG 45GX950A-B 45-inch Ultragear 5K2K - Tilt Adjustment Requires Tools
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).

Absolute Quality
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.

Completely disappointing! Stay away if you have 57'
Please don't promote this Arm as Heavy Duty monitor arm, at least not for Samsung 57" ultra wide screen. As you can see in the video and pics this arm gets obliterated by this monitor twisting it towards the front no matter how many adjustments I've tried. Finally, its SUPER bouncy as the video shows just with a simple touch it start moving up and down.......Completely disappointing! I'm strongly considering returning it.

Great value
Very happy. Bought another after I made sure it met my expectations. Very nice product and easy to use. Could be maybe a bit more buttery smooth in terms of minor adjustments but for the price it’s amazing.

Braccio per monitor STREPITOSO!
Come da titolo, questo braccio per monitor è qualcosa che vale 10 ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ Ero alla ricerca di un braccio per sostenere il mio enorme Samsung Neo G9 da 57". Le prime opzioni che avevo valutato erano però troppo costose. Spendere 300/400€ per un Ergotron mi sembrava veramente troppo. Ed ero quasi rassegnato ad usare la troppo ingombrante base del Neo G9. Dopo lunghe ricerche mi sono però imbattutto in questo ULTRARM di cui ho letto molto bene in giro. Ebbene, mai acquisto fu così azzeccato! Tiene perfettamente l'enorme Neo G9, non solo, dopo aver fatto tutte le regolazioni del caso il monitor non balla neanche se sbatti sulla scrivania. Mentre è possibile eseguire tutti i movimenti con il minimo sforzo. Per quanto riguarda l'installazione, non è semplicissima, bisogna studiare un po' le istruzioni che comunque sono chiare e precise. Una volta capito come proseguire però, il montaggio avviene in una ventina di minuti. Dentro la confezione sono presenti tutti gli attrezzi necessari a stringere le viti e completare il montaggio senza ricorrere ad ulteriori attrezzi. Un cacciavite ed un avvitatore semplificano comunque il tutto. Una tirata di orecchi a Samsung, che mi ha fatto tirare giù tutti i santi dell'anno 2026. Ma come si fa a mettere un adattatore VESA per bracci e NON METTERE le viti per aggancialo? MALEDETTI! Per fortuna questo ULTRARM è dotato di un set di viti di diverse dimensioni che mi hanno permesso di montare il tutto senza problemi. Lo consiglio? Sicuramente si, costa 1/3 di quelli rinomati (e.g. Ergotron o simili) e fa il suo sporco lavoro alla perfezione!
