HUANUO Dual Monitor Stand - Height Adjustable Monitor Mount Fits Two 13 to 27 Inch Flat, Curved Computer Screen, Double Gas Spring Arm Desk VESA Bracket with Clamp, Grommet Mounting Base

These take a little time to assemble, but the result is well worth it. I've got dual 27 inch monitors now that I can position in many configurations. I can now switch from standing to sitting at my desk in less than a minute. I can switch from landscape to portrait with either or both monitors very quickly. I'm even able to swing one monitor to face some exercise equipment so I can watch videos while I work out. The mount is nice quality and feels secure and smooth when shifting monitor positions. My single issue was a difficulty maintaining my monitor in a portrait configuration (my monitors are at the top end of the specs for this mount, and are very bottom heavy). The seller quickly supplied me with a modified bracket that solved this issue.

Twitch Streamer, it's been 8 to 9 months in and it is still holding strong on a glass table, I have one old heavy 27inch LCD monitor that is way heavier than the new 27inch OLED 144hz Curve that I needed because I just upgraded to a Nvidia GTX 1070 Ti Card. Women or men that do not have muscles or endurance please have someone help you that wont tire out on you when making the final adjustments. Do not leave this untighten or you risk damaging the circles, those are not very strong metals so make sure you do exactly as it says in the instructions. I finally put the aesthetics Caps over the holes today, you can leave them for last and very simple to screw in. I DID at first had the monitor totaly on the base not using the pole, today I raised the whole unit up. Yes it is shaky if you bump the table, I'm using a glass L Shape table top from Office Depot constructed with aluminum, I placed a half inch wooden board and it hasn't cracked the glass. The foundation legs are really wide and pretty sturdy. Just use common sense and Physics! Knowing the strength, weight and durability of your table will help. If you like flipping tables this is not for you! So far the one negative is the Cord holder. I have 5 cords coming out of my monitor and it can only hold 3 on the arm organizer, even with three if it's not loose enough and you move the arm the tabs pop out, I gave enough slack for the cords at the elbows so when I raise the monitor up or down I dont have the issue. I used my finger in the picture so you can see the size. It is a standard monitor mount, it has different size holes I guess for a mac? Maybe but it worked for both my Lenovo, and HNC LCD monitors. There is a weight limit. Do not go beyond 27inch. If you have two 24 inch these arms are perfect and you might not need the extender. I started without the extenders and it's really sturdy. I might go back to just one arm. Yes you can just use one or the two, using two arms will make it shake more, but that's only if you have people bumping your desk all the time then no dont use the extended arms. If you have extra anything save the box and its components because if you move or sell these your going to need them. Thank you and I rated this 5 star! 5 star because its lasted me almost a year and the adjustments and adjustment tools came with it. It's two different size hex tools and they did the job. Warning you do need a Philip's screw driver to adjust the turning radius of the monitor from horizontal to vertical or it's going to be floping back and forth.

I bought this to mount two monitors, one above the other. Even though it's rate for up to 27", I mounted a 29" ultra wide monitor above a 34" ultra wide. The larger monitor weighs 14 lbs, which is below the rating of 17+ lbs. I'm not sure it will accommodate two 34" monitors without extending the rear post. The 29" could go an inch higher, but I can't lift the assembly and retighten everything by myself.Pro: The hardware looks nice and is well made. The adjustments are easy to make. The gas cell does it's job. The adjustment must not be critical, because I didn't have to change it, and I have two different size monitors that are different weight. I think it is a good value for the price.Con: It's hard to raise the assembly on the rear post. It's better to set that before the monitors are mounted. This wouldn't be a problem, but it proved difficult to remove the monitors due to the close fit at the pivot joint. Once the weight of the monitor is on the upper arm it's hard to find the magic position that lets the upper arm slide.A minor issue is that the monitors are a tad wobbly. In normal use the sit there just fine, but if you bump them they bounce a little.If I needed another I would purchase this again.

I am using this mount with 2 Samsung C27F398 27-Inch Curved Monitor (Super Slim Design) and I'm loving it. The mount was very easy to setup, it seems to be very durable and engineered quite well. The mounts allow you to move the screen in the X, Y and Z dimensions plus tilt and rotate. Once you get the monitors exactly how you want them you can use an hex wrench to lock it in place. My laptop was only able to drive 1 external monitor at a time so I bought this to drive both monitors through 1 usb3 port: Dell USB 3.0 Ultra HD/4K Triple Display Docking Station (D3100).Note, this mount WILL NOT work on every desk. The mount comes with a C clamp and will fit a desk that has a horizontal "shelve" up to 3 inches thick. My particular desk is an Ikea with no real horizontal shelve to attach the C clamp to. I ended up having to run the mount's leg around backwards and then change how the C clamp attaches to the vertical pole in order to get the mounting system to connect to my desk (see photo). By doing that I was able to move the vertical pole back a little bit, which gave the C clamp enough space to attach to the desk.This is a great product in my opinion, however the designers should take a close look at the clamping system to see if they can expand the number of desks that will work with this product.
