Help me find a similar arm mount

JeffJ · November 27, 2015

First let me explain the setup I'm going for, as this is a bit important:

I'm going for a 4-screen setup, in which I have 3 Dell UltraSharp U2414H on each their own desk mounted arms, and then a fourth screen which is a big 32" monitor that has its own desk mounted arm off to the side.
This is important because the 3 Dells will be setup as my primary surround setup, and the big monitor will primarily be off to the left, raised above the outer most left monitor. When I want to use the big monitor I can pivot off the 2 outer most left Dells more to the left, and then drag the big monitor to the right and lower it down in front of me. This is a very flexible setup that allows me to do everything, but it also requires that the arm that carries the big monitor is very flexible and can go a lot to left, right, up and down.

So with this in mind, this is the big monitor:

And this is the arm that the big monitor would be on:

However, the monitor (which is nearly perfect for all my criteria) is 28.60 pounds, but the arm above (which is also just about perfect in its articulation features) only carries up to 25 pounds.
Even then, it says that for monitors above 20 pounds I may lose quite a significant amount of height articulation.

So, with this setup in mind that needs a lot of flexibility, where can I find an arm like the Ergotron LX that gives me at least the same amount of flexibility in all directions but can carry at least 28 pounds?

To those curious, the 3 Dells will be on these arms:
