Question 1

Can this hold 2 27"  monitors.

Accepted Answer

Yes, so long as they're not ultra wides or wider than usual. I have a 32" and a 27" on mine, the 32" puts it too close to wrap around me so I had to purchase the Ergotron LX extension to help it out. I imagine 2x27" should fit fine. These monitors are right around 20 lbs and it holds them up very stiffly, but that's adjustable.

Question 2

Can you stack x2 34 inch 13.4 lbs lg 34uc89g ultrawide monitors on the ergotron lx dual stacking arm?

Accepted Answer

Sadly the issue is not so much the weight, it's the height.... or lack thereof.  If you have newer monitor that isn't crazy heavy, you will be fine with double stacking 34 inch monitors. I have 4 of these arms, on with the tall pole and have mounted all a 24 pound monitor plus a second 18 pounder on the same mount with absolutely no hint of an issue with weight...in any way. The problem is that the 13 inch tall pole just isn't tall enough to give you the height you need for the second monitor.  Even if you practically set the lower monitor on the damn desk you still barely have room to squeeze a second monitor on top.   I have no idea why Ergotron has not realized that monitors are getting bigger and that they need to raise the height of the pole in order to allow people to mount 2 large screens.  I am looking into having a machine shop make me a 20" tall pole.  I have done a fair bit of research online and others have said that the cost to have this pole manufactured at a machine shop is around $60.  Sad that we have to resort to this because the company that makes the best monitor arms out there can't manage to keep up with the times and offer a product that will work.       It's also annoying that Ergotron will not sell the poles separately as spare parts.  They sell most all the other parts necessary to piece together one of their monitor arms, but not the poles.  So while they may soon be making arm options with taller poles, and despite having already bought 4 of their arms, they won't sell me just the pole so that I can change out the pole... they want me to buy a whole new double arm unit for roughly $300.  What a joke.

Question 3

Will it support x 2 38 inch dell 38” wide screen ips monitors stacked on top of each other?

Accepted Answer

Will it support x 3 38 inch monitors while using the "LX ARM Extension & Collar KIT (98-130-216)" attachment? Two monitors side-by-side and one on top using the Ergotron extension?

Question 4

Does the mount only attach to a desk or can it be attached to a wall?

Accepted Answer

Desk only - The base requires a horizontal surface and the rest of the mount requires a vertical pole.
