Ergotron – LX Single Monitor Arm, VESA Wall Mount – for Monitors Up to 34 Inches, 7 to 25 lbs – Matte Black

I was amazed at how fast the installation of this item was. I want to say I spent less than 30 minutes from the time I started to the time it was up and running. I have set up other mounting arms that attached to the desk or were free standing. With those devices I found that getting the monitor attached to the mounting plate is always difficult. Attaching other devices to the edge of a desk can also be cumbersome.The design of this arm is very simple. The plate that attaches to the wall does not have the swivel arm permanently attached. That makes it very small and light. I located the wall stud and drilled the two 5/16" holes needed in just a few minutes. The mounting bolts are three inches long, so you need to have a long drill bit. I used a 1/4" drive ratchet with a 1/2" socket to install the two bolts. The bolts are listed as 13mm but the 1/2" socket did work. However, it was "snug" fit for the socket.If you don't have a socket set, you may have trouble getting the bolts completely tight. There is a "U" shaped area where the bolts fit. You would not be able to get a crescent wrench or a pair of pliers in there easily.Once the plate was mounted to the wall, the first arm just drops into place on the spindle in seconds.Mounting the second arm to the monitor was also very simple. Four thumb screws are provided. It was very simple for me to lay the monitor on its face and line up the mounting holes. The plate has holes for 100mm and 75mm.The provided thumb screws were the correct size to fit into my monitor. Because you are only holding one of the arms while you attach it to the monitor, it is a one person job. The arm is light enough to be held with one hand while you line up the holes. Your free hand can then start the thumb screws into holes. You are not trying to juggle the arm, a screw and a screwdriver at the same time.Once the arm was mounted to the monitor, it drops into place on the spindle at the end of the first arm. At this point, you have a usable system. By grasping the sides of the monitor, you can move it around or rotate it.The remaining steps are mostly cosmetic. There are two plastic covers that snap over the top and bottom of the wall mounting plate to cover the bolts. There is also a plastic cover to snap over the spindle at the "elbow" of the two arms. That took less than two minutes to put those on. You might want to watch the YouTube video on this arm. It shows the assemble steps.Dressing the cable by attaching them to the arms was a little awkward. Two black zip ties are provided in the package. They are used to attache the wires to the mounting arm attached to the monitor. There are two protrusions on the bottom of the arm that the zip ties go over. You have to do this pretty much by feel when the monitor sits over a desk.The arm attached to the wall has a removable plastic cover that will expose the channel for the cables. I have three cables to my monitor (HDMI, VGA and power). Getting them lined up inside the cover and getting it reattached to the arm was also a little awkward. The cables were a little stiff and kept wanting to jump out of the channel. I was leaning over the desk and the top of the monitor trying to do this.Like some of the other reviews, my only downside on this mounting arm is the instructions. The instructions consist of one sheet of paper approximately 11" by 17" printed on both sides. They show five steps but is it not the logical order in which you need to proceed.Step 1 is a chart that shows how high off the floor the wall bracket needs to be. There are four columns and six rows of entries. Two columns are for 4x3 monitors and two columns are for 16x9 monitors. For each monitor aspect ratio, there is a column for sitting and one for standing. The six rows in the table are for various monitor sizes ranging from 15" to 22".The first time I looked at the chart, I found it confusing. I then realized the variations in the measurements was approximately 2" for a seated user. For example, the wall plate should be mounted 34.9" off the floor for a 15" 16x9 monitor. A 22" 16x9 monitor should be 33.2" off the floor. Since the mounting arm will move up and down approximately 6.5", it didn't really matter how precise you mounted the bracket to the wall.I put the bottom of my wall mounting plate 4.5" above the top of my desk. The bottom of the 22" monitor will come down to approximately 5" from the top of my desk.Step 2 of the instructions was an "exploded" view of all of the mounting arm parts. I don't understand why this is step 2.Step 3 is the wall plate mounting options. In addition to the bolts, plastic anchors are also provided if you want to install this into a concrete wall. The instructions show an optional wall track and bracket that can be purchased separately. That might be nice if you want to adjust the monitor between a sitting and a standing position.Step 4 shows how to adjust the tension. There is a step 4a and 4b for the two different adjustments. Step 4 covers about 80% of one side of the instructions. Most of that is four different warnings in nine languages.Step 5 shows a set screw on both spindles that can be tightened. I suspect that tightening these two screws would lock the arm in position. A 2.5mm wrench is provided to do this. If the first arm is perpendicular to the wall, you would probably not be able to get the wrench into the set screw.I do like this mounting arm. I am considering getting a second one for other monitors on my desk.

The monitor arm is super easy to install. It feels sturdy and has plenty of adjustment for the spring force in each arm. I mounted an Apple Prod Display XDR on it and it was able to hold that extra weight and allows me to tuck my monitor up against the wall when not in use. It also helped to declutter my desk for better organization.

This is a seriously nice product. There are few wall-mount swing arms that offer the versatility of the Ergotron Lx. And there are even fewer that compete at this price, which is substantial but worth it in my opinion.Right out of the box, you can tell that this is a quality product. From the heavy 80mm hardened steel mounting bolts, to the mounting wall anchor with plastic vanity covers for the bolts, to the precision movement in the arm itself, there is no doubt that you are getting what you pay for. The Ergotron Lx both looks nice and feels nice. I am very happy with my purchase, which was hard to do. After all, it's ~$120 just to mount a monitor on a wall. But when you consider the quality of the product with the ergonomic configurations it offers, it's totally worth the cost. And let's be honest, ergonomics are expensive in general, so this is really not such a terrible price.The product installed relatively smoothly. I did not have a drill bit that could completely bore an 80mm hole to accommodate the massive bolts, but after some ratcheting it all worked out. After that, attaching the VESA mount to the Monitor was a cinch with included thumb screws or, if you don't like thumb screws, Phillips-head screws. But who doesn't like thumb screws? Then it was just a matter of sliding the arms on top of their respective mounts. Adjustments for each of the joints could be easily done with an Allen wrench (provided, if you don't have one).Adjusting the Lx was simple enough. You can tighten the spring-arm so that it can support your monitor weight or you can make the joints stiffer or looser per your preference. I found that the joint to swivel the monitor right and left was a bit stiff even at its loosest, but I don't take issue. The adjustment to tighten the spring-arm is hidden so you'll need to read the manual to find that one.The manual was quite detailed in many respects, but could probably benefit from some proof-reading. There are no explanations -- only diagrams. And not all of the items pictured in the diagrams are accurate. Minor stuff though. They'll have a picture of a Phillips-head screw, but be using a hex Allen wrench in the diagram. The manual is also laid out weird so that it's not completely obvious which diagram is relevant. But the product is fairly simple to install so the shoddy manual is forgivable. I found that the suggestion for a 3/16 drill bit to bore the hole for the 80mm bolts was insufficient. I went a little larger myself.Among that which has already been described, the unit also includes a plastic cover underneath the rear "bone" of the arm to manage cables to your monitor. It clips in nicely to neatly hold strong a decent amount of cable. The arm itself has a very impressive range of motion. When you move it up and down, it moves the VESA mount synchronously to maintain the configured angle of the monitor.The reason I purchased this was because my monitor was too far across my desk and I had to lean over to see causing some major issues with my mouse arm being bent and all. Now I have both newly freed desk space as well as much less pain in my mouse arm. Plus I can see the monitor a lot better. I could have purchased a $40 swing arm to get the job done, but the versatility in being able to raise and lower the monitor on-demand is quite worth it. I highly recommend this product.Positives:- Quality Design- Versatility- Ease of use and installation- Ergonomically pleasing- Aesthetic detailNegatives:- Instruction manual needs work- Only supports up to 20 lbs or 22" monitors
