The product itself is good, I have a 24inch and a 27 inch, it would've been nice to position them one above the other but they have other monitor stands for that purpose. This build is good, installation is easy. You do have to tighten the up down elbow allot in order for the monitors to hold their vertical position but it works and thats all that matters. Only complaint is both VIVO-AU and Amazon could not provide a Tax Invoice which I needed to claim back WFH expenses due to our current working conditions. But Amazon did offer an alternative which kinda indirectly makes up for it on my next Amazon purchase.
I used these for grommet mounting on a corner desk. Attaching the monitors to the arms is more difficult than on some higher-end arms where the mount pre-attached to the monitor just clicks into the arm. Here, you're holding the monitor steady while using a hex wrench to connect the monitor mount to the arm.
The arms seem sturdy enough. Not surprisingly, given the price, the movement is not very smooth; however, my biggest complaint is that for my application (a corner desk, using a grommet mount near the back of the corner), the arms are too short. With a pair of only 22 inch monitors, I can't get the monitors close enough to me for good ergonomics. If the monitors were larger, the arms would be even less useful.
I have a built in desk and think I should have mounted it further away from the wall as in order to have it close to the wall the monitor has to be too high. I think if it wasn’t up against a wall it would work much better. It’s very sturdy and well built but not ideal for my situation.
Item arrived on time and is of good quality, however, adjustment options were lacking and could not get the monitors to line up properly. Also had a small issue holding a heavier monitor and had to be tighten a lot which made it hard to move.
When I ordered these, I was expecting to be able to adjust my two 20 inch monitors freely but I guess I overestimated the dimensions. The two monitors could barely be a couple inches apart, so adjusting them was a pain. The field of rotation was also fairly limited. I ended up returning this and getting two of their individual monitor stands which work quite well. To increase the field of rotation, I removed the base plate (on the individual ones) and drilled out the section of metal which restricted its movement. I would recommend doing this because you really get the full benefit with 360 degrees of motion.
I'm 6"1" with not the best posture, so I thought the maximum height of this dual monitor arm would be sufficient enough to position the monitors at the proper eye level. It's about 1-2 inches too low. I had the option of going taller, so I don't knock off stars for my misjudgment. I'm giving this three because 1) The base pivots at the clamp with even the slightest attempt to reposition the monitors, no matter how tight you try to secure it 2) The monitors bounce around when I type, move the mouse, or cause any disturbance on the desk. Maybe it's just not possible to have a truly stable monitor arm, but it's no less frustrating 3) Out of the box, the adjustable joints are all too tight. Nothing moves or adjusts with ease other than the gas height arms. Trying to fine tune tensions on a monitor arm is a pain. 4) I have yet to own a monitor arm that lets you easily position the monitors where they are flush next to each other without a gap and remain level. Micro adjustments are nearly impossible. 5) Finally, the wavy design of the arms result in odd adjustment paths that affect the height of the monitor arm as well as it's horizontal positioning, 6) All of these annoyances by themselves wouldn't be such a big deal, even all of them would be ok with a stationary desk where it's basically a set it and forget it situation. With a standing desk, I need to adjust the position of the monitors whenever I raise or lower the desk, so I am reminded of this products shortcomings multiple times per day. I feel like there should be a better way, but maybe that better way is just outside of my budget.
When I purchased this, I assumed that if the desk mount could handle a couple of 27" monitors, it could handle a 21" iMac and a 23" secondary display. Vivo makes a very nice VESA mounting bracket for the iMac, so mounting an iMac to one of the arms of this stand isn't at all difficult, but the added weight of the iMac requires adjusting the pressure in the gas cylinder to the max. Once that's done, the arm will hold the iMac at any height desired, so in that respect it works quite well, but elevation is only one of the degrees of freedom in this mount. Screen tilt is a big problem, as there's no gas cylinder support for it, and even with the tension adjusted as tight as a sane person can make it, the iMac tends to tilt forward when the iMac's suspended in air. This can be addressed by setting the iMac down so the stand rests on the desktop, but the stand must be pushed down forcefully to get it to lay flat. Apple introduced a VESA-mounted iMac just after I bought mine, and perhaps that would be better suited to this stand, but the other issues would still remain.
An even bigger issue is cable management. There are two fairly generous channels for cables in the lower portion of the arm, securely held in place with a cover that screws down solidly. The upper portion of the arm, however, has a minuscule single channel with a tiny cover that snaps in place. That channel is barely adequate for a power cord and a thin display port cable. It's a very tight fit with a power cord and an HDMI cable. Even then, if the cables don't have enough slack, simply moving the arm will cause the cable cover to literally fly off the upper portion of the arm. Add any other cables and there is just no way to snap the upper cable cover in place. With the iMac, I have a power cord, an ethernet cable, two Thunderbolt cables two USB cables and two audio speaker cables. I tried getting it to work with the cover, but it just won't stay in place. It flies off in all directions with any attempt to move the arm. I ended up removing the cable altogether and using velcro to strap the cables in place - hardly an aesthetically pleasing solution. The channel in the upper portion of the arm should be as large as the two channels together in the lower portion, and the cover should fasten securely with a screw, just as in the lower portion. Why not make the cover as large as the entire upper arm? The result would be attractive, functional and above all else, safe.
As to installation, that was surprisingly easy in spite of my need to mount it to a Vivo CPU mount, which I used to hold my uninterruptible power supply. I had no difficulty at all securing the stand to the CPU mount as shown in the attached pictures. My final concern is with the lengths of the arms. The right arm is, if anything, a bit too long for the 21" iMac. With the elbow barely clearing the window air conditioner behind it, the iMac display is 18" from the wall. One needs a very deep desk to accommodate a computer monitor placed that far forward. In contrast, the left arm is barely long enough place the secondary, 23" display at the same distance forward. Angling it helps, but it's strange that two arms function so unequally for similar size displays. I would recommend spending more money on something more flexibly designed.
PROS: Easy to mount to a desk (I used the clamp). USB 3.0 ports are great (but the cables that come with this bracket are WAY too short (five feet)) but you might want to order longer cables if your CPU is more than a couple of feet from the monitors. Get rid of you monitor stand and make it look like your monitors are "floating".
CONS(2): 1. The cable management system is one cover that screws on (no issues with this) but the second one which would be closest to your monitor is pretty much only designed to work with a Display Port size cable and a modern monitor that uses a small thin power supply cable. If your monitor (like one of mine) uses a DVI cable and the "old" monitor power cables with the three prongs then the snap on cable management cover is too small. You will not be able to use it and move the monitor. I could either put the cover on...or move the monitor...but not both. once the cover was on (and I spent 45 minutes trying this) if you moved the monitor to position it where you wanted it...the cover would pop off.
2. The fact that the monitors can be moved in so many axes which is a reason why you want to buy this is also one of the reasons I took a star. With a standard monitor stand all you really have to worry about (assuming your desk is level) is really just the height and forward/back tilt of the monitor. With these you have to worry about every axes. It's great for getting your monitor into position, but when it comes time to fine tune your monitor (lets say to make it level and not tilted) the fact that you have to have the screws tight enough to hold the monitor in place causes you to have to "twist" the monitor past the point so when you let off pressure it snaps back into place. Well..doing so knocks one of the monitors into the other one (I want my monitors as close as possible to provide a "seamless" desktop). Now you think "why don't you just move the monitors apart...get them level..then move them back into position". With so many axes of motion as soon as you try to move the monitor back next to its neighbor you move it off one of the axes you just fixed and are basically back at square one.
One side doesn't tighten properly and monitor droops constantly and has to be readjusted. Otherwise a great monitor mount. Both monitors are within the weight spec limits of the mount but I still have issues with the right side not staying at the adjusted vertical angle where the monitor pivots. It slowly changes angle over time and has to be readjusted CONSTANTLY. Even if not touched. My desk is solid, so its not a vibration issue and its ONLY the right side vertical angle.
