Review: Loving it, great for LG C2 42", (Additional Vesa Adapter required!) - Why did you choose this product over others?: I have heard about the ergotron brand before and always seen good reviews of it despite of its cost. Functionality: To my surprise this is loaded with all the features, move up and down, tilt sideways tild upwards and downwards, move forward and backwards, just all around pretty much a 360 movement, well 180 for the base and almost 360 for the monitor. Mobility: Takes a bit getting used to with the movement, if you make it more stiff to move, expect it to be hard to do small adjustments but it will stay in place and will not wobble, or you can loosen it and it might wobble a bit more but will be super easy to move about. Cable management: On the back there is 2 ties for cables that run along the arm and a plastic shroud that hides the cables going down behind the table. Easy to use and access. Desk space: I used to have my monitor up on a small elevated riser, and got tired of all the wobble from it, and while that took up a lot of space, this one saves quite a lot, to the point that I dont even know what to do with the empty space :D Totally loving it, it holds an LG C2 42" just fine, but it DID require a vesa mount adapter 300x200, as the included one only goes up to 200x200. so much cleaner on the desk and I can move the monitor closer any time I want to or further away if I dont want it to be up close. Assembly is also very simple, I did not drill a hole into my desk so I used the end clamp and it clamps on very strongly, the base is heavy but i have a table that is roughly 3cm in height and is made of solid wood so no issues with that. The first part slides into place easily and the second also, clipping on the monitor was a breeze even alone so you dont necessarily need 2 people to do it, clip attached, screw in from the bottom and it wont go anywhere! as stable as it can be.
Review: Best monitor arm available for the Samsung Odyssey G9 - This monitor arm paired with the HX Heavy-Duty Tilt Pivot is the perfect solution for desk mounting your Samsung Odyssey G9 or I'm sure any other large and heavy ultrawide screen such as the LG 49" one. The arm is extremely well made and feels premium in every area, from the assembly through to the motion of moving the monitor around on it being extremely smooth. I do find occasionally trying to move my monitor, I have to swing the monitor one way to then be able to get enough friction to move the part of the arm I'd like, which can make it a bit akward to get it exactly where you want it. That could just be down to certain areas being too tight though which I could loosen up with the included allen key. The arm isn't going anywhere though, I've got it mounted my sit / standing desk, and when I move the desk up or down, the screen stays solid. When I'm typing on the desk, the massive screen doesn't really move much at all compared to other monitor arms out there, a true demonstration of the superior build quality of Ergotrons Monitor Arm.

## Questions & Answers

**Q: Would this hold a samsung super ultrawide curved gaming monitor (c49rg9) 49 inch**
A: Works well I’m using this with the same monitor as you also. Holds the monitor rock solid and stable.

**Q: Will this work fine and hold with lg cx48? moving it around would that be an issue?**
A: I don't know the weight of LG CX48 so cant directly answer - However I had my Alienware curved AW3418 DW weighing 7.27 Kg  on the Ergotron  and it was fine and moved around  very well.  However when I upgraded to the Samsung 49" Odyssey Ultra Curved monitor this was too much for the Ergoton to handle. Although the weight was within spec the overhang with the massive 1000R curve made it too heavy.

**Q: Does your desk have to be solid to use this vesa mount with the Samsung 49inch ?**
A: I have it setup with the G9 Odyssey 49. 
You will need the Ergotron heavy-duty tilt pivot (part number:  98-540-216) to support the forward weight of the screen (due to its 1000R curvature). Re the desk, I’ve sandwiched a piece of hard wood between the desk and the arm’s fixtures for extra support (I’m using IKEA’s BEKANT desk). 
I hope you find this useful.

**Q: Will this hold the Samsung Odyssey G9?**
A: It will only hold it if you purchase the HX heavy duty tilt pivot with it. Once you get that replace it with the one that comes with the arm.

### ⭐⭐⭐⭐⭐ Possibly the best Arm ever - but at a hefty price tag
*by D***Q on 5 May 2022*

I bought this as I had a desk stand from Ergatron - their products are well made and well constructed. The arm is no exception, it's even easier to install. The range of motion is restricted however to the first column which doesn't swivel 360 degrees which limited the ability to stow away the monitor from a desk (if like me you use it on your kitchen table). My monitor is very large (Samsung 34J890) and the attachment that comes with the arm supports it with no issues at all, so need to for the extra for larger monitors. Overall excellent kit but very pricey
