I mounted my two 27" AOC monitors side-by-side on two VIVO Single Monitor Desk Mount Fully Adjustable Articulating Stand /For 1 LCD Screen up to 27" (STAND-V001M) [https://www.amazon.com/gp/product/B00YJEQ83G/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1] and I am very happy with the result - see photos.My monitors are:AOC - 27" Widescreen Flat-panel IPS LED Hd Monitor - Piano Black/silver [https://www.amazon.com/AOC-Widescreen-Flat-panel-Monitor-silver/dp/B00J4X1P7Q/ref=sr_1_1?ie=UTF8&qid=1469895876&sr=8-1&keywords=I2757FH]QUALITY: These mounts are beasts - in a very good way. They are built out of very heavy gauge steel and are exceptionally sturdy. This is why I purchased them, right?MOUNTING: Originally I was going to use the grommet mount option because my desk came with two grommet holes and accompanying wood-fill discs, allowing easy pass-through of cables, etc. I experimented with that approach and swapped the hardware accordingly. However, after experimenting with actual monitor placement, I discovered that the default C-Clamp Mount option gave me more flexibility in my mounting options. I have a couple of wood montior stands that I used to support these same AOC monitors with their default desktop stands. I really like them for storing desktop items like pens, glases, etc., so that they are conveniently accessible but without cluttering up my desk. This makes dusting and cleaning my desktop much easier as well. Also, I liked the fact that the flat back of the C-Clamp can hug against my desktop edge, making the mount that much sturdier. The grommet mount attaches solely against the top and bottom of the desk with no side support. However, don't get me wrong - it was rock-solid steady, if that meets your needs. I had no concerns about mounting my monitors via the grommet mounts if that would have better suited my needs. They were solid. But the back-plate of the C-Clamp hugging tightly up against the back edge of my desktop just added that much more support to a mounting option that gave me the placement flexibility I ended up needing.I would suggest getting used to the hardware during initial setup and experiementing with the arms and their placement before deciding on your final mounting and placement options. Since I was mounting the AOC monitors, I had the additional steps of attaching the aforementioned brackets to the VESA plate of the mounting arm. But when all was said and done, mounting the AOC monitors were a cinch due to the bracket accomodating the AOC chrome arm that extends off the back of the monitor. All I had to do once the arms were fully mounted and placed where I wanted them was to slide the AOC monitor arm into the receiving slot on the bracket that was now attached to the mouning arm. They also had set screws that can tighten the final mounting of the AOC monitor to its bracket, but I found that I did not need them. The AOC chrome mounting arm extends so far down into the bracket that it creates more than enough stability for my needs. If an earthquake happens that can cause my monitors to jump four inches out of a snug receiving bracket ... well, I will have bigger problems on my hands anyway. :-) Since the AOC monitors have a degree of tilt built into their default chrome mounting arm, this made my final positioning of my monitors all the more easier.I researched a lot of different mounting arm options for before deciding on these from VIVO. I originally looked at dual-monitor mounting arms, but changed by mind due to considerations regarding ultimate placement flexibility. An important factor for me was the ultimate mobility and positioning of these particular arms. They allow the monitor to be positioned pretty close to the mounting pole, if that is desired. Other models did not always accomodate that flexibility.These arms by VIVO rock and I will not hesitiate to purchase their products in the future.
