I have 2 ergotron arms, that I'm now using for big TVs - one desk mounted, one wall mounted. Super strong and sturdy, with every option possible, I think - up and down motion, tilt forward and back, full 180 degree rotation, and I use them all. One TV is way too big for the space I put it, so when not in use I flip it 90 degrees and fold it up against the wall; works great.

I bought arm this to go with a sit-and-stand adjustable desk I recently got for my home office. It's rugged and well made and awesome! The arm lets the monitor go from a height of 48 (for sitting) to 63 (for standing) as measured from the floor to the top edge of my LG monitor (also bought on B&H). I bolted the arm into a wall stud (found with a studfinder) using the two high-quality lagbolts that came with the arm. That is rare — usually the fasteners that come with stuff like this are really junk ... so typically I just chuck them and use my own. Not here! Before mounting I used the joint key to loosen each arm section to see how much force it would take to articulate. I was a little nervous the arm joints were overly stiff. Once the monitor was bolted to the ... MoreI bought arm this to go with a sit-and-stand adjustable desk I recently got for my home office. It's rugged and well made and awesome!

Before mounting I used the joint key to loosen each arm section to see how much force it would take to articulate. I was a little nervous the arm joints were overly stiff. Once the monitor was bolted to the arm's VESA end though, the arm joints moved effortlessly ... and in fact I had to use the joint key to retighten the joints a little. I like very much that the joint key is somewhat ergonomic to make that adjustment easy. If you have a cordless drill, installing this takes less than 20 minutes. If you absolutely cannot avoid mounting this onto hollow drywall, I strongly recommend throwing away the plastic sleeve things that come with this and using Toggler brand toggle bolts instead.

This was a bit complicated to install in that I actually hired someone and they had real issues figuring it out in terms of how high it would go etc... hard to explain until you try. He actually messed it up and had to re-install it higher. Part of that was just due to him not being the sharpest pencil in the box but I could see how it was confusing. Now that it's mounted it's great though. Super sturdy. No complaints!
