Ergotron – LX Sit-Stand Single Monitor Arm, VESA Wall Mount – for Monitors Up to 42 Inches, 7 to 25 lbs – Polished Aluminum

The Ergotron LX Sit-Stand Wall Mount is great. Easy to assemble and install. Installation requires a drill, socket (preferred) or wrench, a way to find a stud behind the drywall, and a bubble level (you can download a free smart phone app for this). Once the tension is set it easy to move around and stays put. Very solid construction. Hopefully, it last a long time.Notes:- The cutout for the lower mounting bolt is smaller than the top cutout--make sure the pilot hole goes into the wall straight. If the bolt goes in with a downward tilt there won't be enough room to get the socket onto the bolt head.- Because of the design, it offers more maneuverability if the wall mount is in front of the user. I've got it mounted off center from my desk and it still works well.- When all the way back against the wall (both arms parallel to the wall and folded on top of each other) downward movement is limited since the lower arm blocks the upper arm's downward movement.- To help visualize how this moves I'll describe each joint:- Wall mount/lower arm: fixed height, rotates 180 degrees (wall blocks additional rotation).- Lower arm/upper arm: 360 degree rotation. Upper arm has a hinge that controls monitor height.- Upper arm/monitor: 3 axis hinge. 180 degrees rotation, monitor tilt (only about 5% downwards), monitor orientation.- Longer than normal power and video cables will be necessary.

This is absolutely a fantastic wall mount for mounting large monitors. I ordered one for my 34 inch Asus Ultrawide monitor as I have a glass desk which excludes me from many desk mounts. Plus the 34 inch monitors are quite heavy all these considered. I saw this mount in a YouTube video and the gentleman had an LG 34 inch widescreen monitor mounted and it moved around so well.I mounted this to the wooden stud in the wall and screw my monitor on and the results are excellent. So many different orientations. I cleared up so much desk space and it looks so professional. The materials are solid and the mount doesn't shake. It sits exactly where you place it.My buddy who also has two 34 inch monitors struggled with a desk mount having to put books under it to try and hold the weight ordered two of these for his monitors. Mounted both and they look great. This is an amazing product and I recommend it for anyone with a large monitor that wants to get it off the desk or has a glass desk that eliminates clamp down desk mount options.

I got this for my wife so she could get her 27" monitor to the front of her desk as her vision went south after her stroke. This was s3everal times as expensive as the wall stand it replaced but well worth it. It is REALLY stout and the tension adjustment in the arm is terrific. The central screws in the mount did not line up with the stud beside the window trim so I took it to my home shop drill press and drilled the other holes that are off center and mounted it that way - no problem. You can get wall stand mounts a lot cheaper than this on BUT when you get and use this one you will see why the extra money is worth it.

I'm using this arm with my 30" Apple cinema display. I couldn't be happier with this thing. It was easy to install and get working. The only issue I had was getting the pretensioning tight enough for my 30" display. I know the display is little big for this arm but I couldn't find anything this versatile for the 30". I am very pleased with this arm and will recommend it to anyone. When I'm rich and famous I'll get a few of them to mount up my multi display setup.

I received this product promptly and beautifully packaged. The instructions were clear, parts wrapped individually. The product looks incredibly well made. But be aware that it's quite bulky. It is also fairly heavy, appears to be very well made, but looks like RoboCop's arm on your wall! When fully extended, it will be quite a distance from a wall so be sure that the location you plan to use it, is appropriate for this product. Had no problems installing it (am female and good with tools) and adjusting tension and it provided perfect support for a 24 in Dell monitor. The photos of the product just make it seem like a more slender profile so be aware those arms are large. Aesthetically it may overwhelm a home office. It looks very industrial.

Unit does not accommodate extension sold separately without cautionary notation. Very expensive product which I would not have bought if I had been warned that they were not compatible. Neither vendor, Ergotron nor Amazon were accommodating. I thought I was doing the best in buying the better product. Would not buy anything from this vendor in the future.

This is the beefiest monitor mount I could find. I wanted to be sure I got one that would held its position well. This definitely lives up to my expectations. It has an excellent range of motion and is very easy to adjust. I like it so much that I bought a second one and will be looking forward to having dual wall mounted 27" monitors for my home office.

Very sturdy unit, has the feel of money, looks great. Only problem was trying to add an extra arm. Ordered extra arm to extend reach but extra arm was a smaller model. Thought HD was the key, so bought an HD wall unit just for the extra arm, but it was also the smaller size. Ended up buying a other of these, just for the arm. No way to buy just an extra arm in the large size by itself that I could find. After all that expense and hassle, now am very happy - holds big monitor over big recliner chair in an elegant den very well. And looks great!
