AVLT Dual 13"-27" Stacked Monitor Arm Desk Mount - Fits Two Flat/Curved Monitors, Full Motion Height Swivel Tilt Rotation Adjustable - VESA/C-Clamp/Grommet/Cable Management

I was looking for a solution to stack my two 27" monitors with the lower one angled up touching my desk, and the other one directly above it resting on it. This monitor arm allowed me to do that. It does take some fiddling with the arm angles to get it just right. I did adjust the arm tension, but without the top monitor resting on the bottom monitor, it won't hold the top monitor suspended. It may require more tightening of the tension bolt, but something to be aware of. My monitors are a bit older and probably heavier than most modern monitors.Update: After additional adjusting of the tension, the arms can indeed hold my monitors suspended in the air.

Love how much freedom it has in adjusting the monitor positions and viewing angle. Seems extremely durable and well built.

Packaged well with reasonably clear instructions. Was worth taking the time to take everything out of packaging and lay it out while reviewing instructions. I am hugely glad I followed that recommendations. That said, this is really easy to put together.One can install with an included clamp; or install through a hole in the desktop (grommet hole might work if it is in the right spot). The warning about cutting the bands holding the arms together sounded really dire. I did follow it; and I've no regrets. But I think I could have simply used one of my handy clamps and done it all myself. There is spring tension, but way less than the labeling lead me to believe.Take your time with layout. It'll pay you dividends later. I mounted a pair of 22" monitors which still affords me a lot of wiggle room to adjust.All this said, I am loving it! I stacked my monitors for that application. After a bit of fiddling with Win10 display settings I got everything set up well to mouse between the two. Being able to tilt the upper monitor is FANTASTIC. While monitors generally tend to stay in place once they've been set up; it is nice to be able to adjust.I have a second system with a pair of 27" monitors. I think if I can cut a deal with the seller to accept return if it doesn't work out; I might be inclined to redo my office system with stacked monitors. But I'm going to give it a couple weeks with the one setup before I decide.Bottom line, if you read the included instructions; give yourself some time to think through install options; you'll be able to get this set up in about an hour (after think time).

Right out of the box I could tell that this mount was of high quality based on the heaviness and sturdiness. This is a good mount for people who want to stack their monitors vertically. If you don’t want to stack vertically, then I would suggest getting a cheaper one that only has the ability to support side by side mounting. This one does that too, but it’s a bit more expensive. I previously had two separate monitor mounts with my monitors side by side, with one in portrait mode and one landscape. Coming from that setup, my only complaint is that there is a bit of bouncing/jiggle of the monitors when slightly bumping the desk or VERY excitedly gaming.

Not sure why there are negative reviews where they cannot get dual monitors stacked.I have two, a AOC CQ32G2S 32", and a Samsung Odyssey Neo G8 32", both are curved monitors with the Samsung being a very curved 1000R it was not easy finding a desk mount that I could stack both vertically.The biggest challenge is getting the tilt joint tight enough to where the Samsung did not tilt forward, and after a lot of tightening it finally stayed in place.The swing arms also need to be adjusted so they are a lot stiffer than what they were set for at the factory. I turned each adjustment bolt a good 3 full turns before even attempting to set the monitors on them and that was close for the top but the bottom pretty much needed the adjustment turned all the way out. The Samsung weighs in at 15.4lbs without the stand and the AOC is a good 2-3lbs lighter so they within the weight limits and the stand seems to handle it perfectly.I'm using the included grommet mount since my desk has a hole for that but do wish they had a larger mounting base just to give the bottom a little more stability, other than that this mount is perfect for my needs.

This unit is solid, it clamps firmly to the desk, and I feel confident that my monitors are held safely. The articulation is satisfactory for most needs. I understand I am at the extreme of the "supported" monitor range so sort of understand that it's not perfect. I run 2 32" curved monitors and am able to barely get them to stack vertically on this mount. While it does work, the bottom monitor is only about .75" off the desk and the upper one needs to be angled toward me enough to make the space between the upper and lower monitor appear as an oval. This gives the illusion that the monitors are never in alignment. This would be the case with any vertical configuration, so I don't hold that against this mount in particular. What I do not care for, and that is in the manufacturer's control, is that I am at the extremes of the upper and lower portions of the mounting pole and that I have to move the lower as far as possible toward the pole and the upper as far as possible away from the pole in order to align them vertically. While this does work, it leaves no room for fine adjustment. I think if a person had any size smaller than 32" or flat screens, this mount would be 5 stars all day.
