Update 11-Dec-2009: Quad Monitor Arm with three 24" Monitors

The original mod of the DS-100 Triple (with the 46" crossbar) and the Neo-Flex HD hung three 22" monitors off a single Neo-Flex HD. The max monitor size on the 46" crossbar is 22". After upgrading to 24" monitors I contacted Ergtron and was able to get a 55" crossbar.

The 55" crossbar will support three 24" monitors (and possibly larger, depending on the exact monitor size). I also used a second Neo-Flex HD that I already had to provide better stability and weight distribution.

I was able to successfully complete the mod, and hang the 55" crossbar on the wall with two Neo-Flex HD mounts. It combination was able to easily support the 24" monitors, offering better performance than the original mod.

Introduction (Original)

This review has been a very long time in the making. I first contacted Ergotron in June of 2006 about getting a monitor arm for review. I was looking for something to mount my 30" panel, a Dell 3007WFP, on the wall, so that I could free up the desk space underneath it. I was looking for something that would provide full range of motion, especially lift. The 30" is a large and heavy piece of equipment, weighing in at over 25 pounds. The only arm that offered full articulation for a monitor of this size is the HD45. Ergotron sent one to me, and I worked to get it installed.

As usual, I over-engineered what I needed. The HD45 is a major piece of equipment which requires special installation. I quickly found out that it simply isn't fit for residential installation. I contacted Ergotron, and they graciously swapped it out for the Neo-Flex HD. That was over a year ago, and I have yet to complete that original review. I liked the Neo-Flex so much that I turned to Ergotron when I started looking into monitor arms for my Surround Gaming setup.

Ergotron doesn't make a wall-mount arm for three monitors. I searched through their product catalog and found that two different arms could be modded to work together. To make it all work, I bought another Neo-Flex HD Wall Mount Swing Arm, and a DS-100 Triple Monitor Stand.

Ergotron Neo-Flex HD & DS100 Triple-Monitor Stand Review - The Hardware

Neo-Flex HD Wall Mount Swing Arm

Included Hardware

The Neo-Flex HD Swing Arm kit includes the wall bracket, the swing arm, the 75mm x 75mm VESA monitor bracket, VESA adapters for larger monitors (100mm x 100mm, 200mm x 100mm, and 200mm x 200mm), and the mounting hardware (2 lag bolts, washers, and other assorted screws). It also comes with installation instructions and an ergonomic guide.


The installation instructions are very simple.

  1. Find a stud
  2. Drill pilot holes
  3. Use the two lag bolts to secure wall mount in place
  4. Place swing arm onto wall mount
  5. Attach the VESA 100mm adapter (if needed)
  6. Attach the VESA mount to your monitor
  7. Place the monitor onto the swing arm

This simple list should not serve as a replacement for the actual installation instructions. Please ensure you read all the directions before installing one on your own. This mount is designed to hold 50 pounds, and needs to be properly secured to a wall stud. Also, please ensure that install the monitor at the proper ergonomic height. Since the monitor will be permanently attached to the wall, and not have a height adjustment, proper height is key. I initially installed my 3007WFP too high, and ended up with constant neck and back pain. After reinstalling the monitor at a proper height, the pain disappeared.

With the monitor bracket and the arm being two separate pieces, the placement of the monitor is very simple. When I originally attempted to install the HD45, the arm and monitor bracket was one piece. After attaching it to the monitor, it became heavy and unweildy when trying to place it on the wall mount (another reason the HD45 isn't suited for residential installations).


NeoFlex-HDPerformance is hard to define for a wall mount monitor arm. It's not something that is easily benchmarked. The arm provides three degrees of freedom. It offers a 180 degree pan, a 180 degree arm swing, and a tilt with -5/+15 degree range of motion. The arm moves and articulates easily in the pan and swing movements. Even a 30" panel is easily moved with one hand. The tilt movement is performed by first loosening a screw, making the adjustment, and then re-tightening the screw. I set the tilt only once, when I first installed the monitor, and it was easy.

The real benefit comes from getting the monitor up and off your desk. My 30" panel was originally sitting in the corner of my desk. I also ran wires such as USB cables and speaker cables through holes in the back corner of that same area. It was a significant pain to make changes to my setup, as I had to work around the large panel, which filled the entire corner. With the Neo-Flex HD, I was able to simply move the monitor out of the way to rearrange anything in that area of my desk.

Pulling the monitor up off the desk allowed me to place other items on my desk, where the monitor stand had once been. This provided a significant improvement in making maximum use of my desk space. The Neo-Flex also has a cable track, to help reduce cable clutter on your desk.


I have absolutely nothing bad to say about the Neo-Flex. It is attractively designed, installs easily, and performs perfectly. The benefits of mounting your monitor on the wall, and getting rid of the monitor stand can't be overstated. I would highly recommend the Neo-Flex HD to anyone looking for a simple monitor arm for a large display panel. If you have smaller (and thus lighter) monitor, and are looking for something with a height adjustment, Ergotron also offers the LX Wall Mount.

DS100 Triple-Monitor Stand

Included Hardware

The DS-100 Triple Monitor kit includes the base stand, the center arm bracket (good for installing two monitors), two arm extensions (needed for three monitors), 75mm VESA mounting brackets, 100mm VESA adapters, and mounting screws. Like all Ergotron products, it comes with full installation instructions and an ergonomics guide.


Installation of the DS-100 is an deceptive mix of "quite easy" and "daunting." The initial steps to assemble the monitor stand are very easy.

  1. Screw the mounting pole into the base
  2. Secure the mounting pole with screws
  3. Attach the center arm to the pole, and tighten
  4. Attach the arm extensions to the center arm
  5. Screw the VESA mounts to your monitors
  6. Attach the center monitor to the center mounting location

DS-100Here is where it gets hairy. The instructions then show attaching both the left and right monitors in the same step. But, without an extra pair of hands, this is impossible. And, attaching one monitor at a time will cause the whole assembly to topple over - I know from experience. My strongest recommendation is to get someone to help you in attaching the outside monitors. This allows you to set the bar height at the appropriate level first, and then attach the last two monitors.

Otherwise, you have to come up with a work-around. I ended up lowering the arm so that the center monitor rested on the base. I then attached one outside monitor. It did cause the assembly to tip, but because the monitors were basically touching my desk already, it only tipped about a 1/4". I then attached the last monitor, and fought to raise the monitor bar. I think I ended up needing help in the end.

With help, the installation is dead simple. Without it, you are in for frustration and fear of seeing hundreds of dollars in LCD panels crashing to the floor.


The monitor arm performs quite well, but it does have its frustrations. The monitors attach securely, and easily. But, I have yet to get all three monitors to line up perfectly. The largest issue is that the outer monitors sit about an 1/8" lower than the center. I believe this is because the monitor arms are torquing (twisting) down slightly, causing the monitor to drop. It's not a big issue, and is really only evident when starting at the Windows desktop. The offset is entirely unnoticeable when gaming. It hasn't bothered me enough to contract Ergotron yet, but I probably will before too long. If I get a solution, I will update this review.

I also have a slight gap between each of the monitors. This is caused because the monitors move slightly as you screw down the knob for the bracket. This later issue could probably be corrected with getting a second person to hold the monitor in position as you tighten the knob.


In the end, the arm performs its function of holding the three monitors securely. But the anal-retentive part of me wishes I could get the monitors to line up perfectly. I wish that Ergotron made a wall-mount that was designed to support three monitors, and I wish the bar was one rigid piece. But, without that option, I was forced to utilize a simple mod to attach the DS-100 bar to a Neo-Flex HD Wall Mount Swing Arm. Continue reading for details on that.

Ergotron Neo-Flex HD & DS100 Triple-Monitor Stand Review - The Mod & Conclusions

Article Type: 

Modding of the Neo-Flex HD & DS100


This is a mod/hack of products produced by Ergotron. I am using both products in ways not intended by the manufacturer. Even though I have full faith in my installation, Ergotron would certainly not provide warranty on any claim if the installation fails. The full weight of the DS-100 arm and three 19" monitors may be exceeding the weight limit of the Neo-Flex HD with the Wall Mount Swing Arm.

The wall mount is rated to hold displays up to 50 pounds and 32 inches. The full weight of the DS-100 arm and monitors is 38 pounds, but the weight rating of the Neo-Flex wall mount may be diminished with displays more than 4" deep and over 32" inches wide.

This setup is certainly more than four inches deep, and measures 45" across. I tested the Neo-Flex wall mount before I hung the monitors to ensure it would hold. The key to success with this mod is proper installation of the Neo-Flex into a wall stud.

If you attempt this mod, you do so at your own risk and will not hold Ergotron or the WSGF responsible for any damage to yourself, your wall, your monitors, or anything else.

The Need

As stated earlier, Ergotron doesn't make a Wall Mount Swing Arm to accommodate triple monitors. Luckily, Ergotron provides detailed dimensional illustrations on all of their products. I was able to determine that the mounting pole on the DS-100 has an outside diameter of 1-1/2" inches. This means that the clamp on the monitor bar has an inside diameter of this same 1-1/2" when fully tightened. I was also able to determine that the wall mount on the Neo-Flex HD has an outside diameter of 1-3/8" inches. Based on these dimensions, I needed to find a bushing that filled the 1/8" gap between the two pieces.

I figured some sort of pipe bushing, or thin metal pipe such as electric conduit would work. I went to my local Home Depot with the swing arm and the monitor bar, and my trusty tape measure. I found that 1-1/2" electrical conduit was the absolute perfect size. Even though I only needed 4" of conduit, I had to buy a 12' section.

The Mod

I took the conduit home, and used my Dremel tool to cut off 4". Then I used the Dremel tool to smooth the rough edge from the cut, and to smooth the inside seam. Once I did this, the conduit fit snuggly on the Swing Arm, but moved smoothly as I spun it. I installed the Neo-Flex, and slipped the bushing into place. I then installed the center monitor on the arm, and placed the monitor on the bushing, and tightened the clamp. Finally, I installed the two outer monitors, hooked up the cables, and routed the cables through the cable management system on the arm.

Overall Conclusion

While I wish that Ergotron would make a Wall Mount product for those of us with Surround Gaming rigs, I am more than happy with the Ergotron products I am using and the mod to make the Neo-Flex and DS-100 serve my needs. All of the Ergotron products I've seen are both well designed and well manufactured. They come with extensive installation instructions and excellent guidelines for proper ergonomic position.

Specifically, the Neo-Flex HD is an excellent product. It installs dead-easy and performs superbly. Ergotron supplied the original one (for the 30" panel) for my original review. While it's taken over a year for that review to now materialize, I was so pleased with the product over that time, I purchased another Neo-Flex and the DS-100 with my own money. There's not much higher praise that I can give to a product than that.

The DS-100 does have its quirks with installation (get some help), and in getting monitors aligned. But, if you want a wall-mounted option, it is the only way to go. Ergotron also offers the LX Triple Display Lift, which has easy height adjustment. I know that Paddy has one of these and he is quite fond of it.

My recommendation is to seriously consider getting your monitors up off your desk, by mounting them on your wall. The freedom to make better use of your desk space is damn-near a liberating experience. Once you make that decision, I would highly recommend a product from Ergotron. Even though this review has taken well over a year, and I'm sure the folks at Ergotron thought I had simply swindled them out of product, I never received a single email or call about the status of the review. Their products are consistently good and their staff is great to work with. Their sales, support and marketing people were all helpful, professional and courteous.
