I mounted Titan Army N34QW 34" Curved Ultra Wide screen. And it hold up ok.

We have been using these monitor stands for a few weeks now and I am very impressed with the product overall. Pros: They are strong, quite well designed and come with everything you need to install them. They have quite good cable management. Cons: The arm joints have a maximum bend of about 90 degrees in either direction, but a wider range of movement would make the brackets easier to use.

The Loctek DLB111 monitor arm was perfect for my needs. Being a budget option I expected poor build quality, but I have found this arm to be incredible tough and well made. It was relatively intuitive to put together and took about 10 min to get set up and installed. If I had to point out a con, it would be that the arm is quite bulky, and when bunched up behind the monitor between a wall, does require more clearance than I'd prefer aesthetically. However, I can hardly complain about that given how robust the arm is functionally. I will be purchasing another one of these when a third monitor is required.

Super sturdy mount and easy to set up. Which is lucky as my unit did not come with the instruction manual in the box - no information is available online not even from the Loctek website.

Bought it to hold a second screen for my iMac. Keeps the desk area underneath the screen clear and easily clamped onto the back of my desk. Would definitely recommend.
