Although the description states the monitor mounting bolt pattern is MIS-D, it does not state what size. So, before I bought the arm, I looked at Ergotron's site which states it is 100mm & 75mm. The unit I received actually has an Ergotron sticker on it -- so there is no doubt it is an HP-branded Ergotron unit -- and it does indeed have MIS-D holes at 100 & 75.

Another thing the description missed is the desk clamp's thickness capacity. The desk clamp is basically two assemblies: 1) the bracket the arm base attaches to, and 2) the hand screw that tightens it all to the desk. The screw can bolt to the bracket in three possible positions, each 1" apart -- and a hex-key is included so you can take it apart and reassemble it where needed.

In the first position, and the screw retracted fully, the arm can be clamped to desks that are approximately thinner than 5/8" (in this position I couldn't attach it to a 3/4" desk). In the middle position, the arm can be clamped to desks that are approximately 3/4" to 1 3/4". And in the widest position, the arm can be clamped to desks up to approximately 2 1/2" thick, maybe a tad more. The screw itself can be tightened through a range of 1 1/4". Again, this is all approximate because I didn't make measurements until after it was attached and I was writing this review.

There is a second mounting method. Parts are provided to eliminate the clamp and convert the arm base so it can be attached via a bolt through a hole in the desk. This has the potential to be more sturdy -- there will be no flex without the clamp -- and also will allow mounting inward from the edge of the desk (i.e.

This monitor arm is just like the Ergotron LX but for considerably less money. Unlike the Ergotron LX, this HP-branded unit it is mostly matte black in color instead of shiny chrome and multicolored. I prefer the all-black color scheme and appreciate how it fits in with the Dell U2410, U2412M and U2405 monitors on my desk. The matte color means dust will go unnoticed for longer.

The unit comes with an adjustable desk clamp which should work on any thickness of desk up to 2.8-inches. It also comes with the standard hole-drilling plate with 3-inch-long bolt, 3-inch by 2-inch backing plate and wing nut if you want to drill it into any surface.

I was happily surprised to find out it supports the rotation of the monitor in either direction a full 90-degrees, a fact I didn't see in the item specifications at the time I purchased it.

I mounted a Dell U2410 which weighs 14.3 pounds (6.50 Kg) without the stand (that's what Dell claims, I believe its more like 16-pounds). This arm states it will support up to 20-pounds. I had to tighten the height adjustment screw with the included 4mm allen wrench so it wouldn't float down. In order adjust that screw, the top portion of the monitor arm needs to be fully extended upward (like in the picture) so the adjustment bolt is exposed head-on instead of at an angle. This can be a problem if the monitor arm wants to float down.

The top (showing) desk plate takes up about 4.5-inches deep by 6-inches wide by approximately 1/2-inch thick. The top plate has rounded corners and edges, which is hard to see in the supplied Amazon images. The round logo in the pictures has an HP logo written in 1/8-inch relief, it's entirely black and comes with a round clear sticker protecting it.

This is a HP branded Ergotron LX Monitor arm. But there are some differences between the two. Obviously the main difference is the color. The HP version is black painted where the Ergotron is polished aluminium. Oddly enough Ergotron uses a black bolt/nut on the main arm where the HP uses a silver one which breaks up the overall black color of the HP version. Some will prefer the black color but it's less durable in the sense that the paint can chip, scratch, and fade with time. It will also show dust more easily but then again most monitors are black anyway so you have the same issue with the monitor itself. The base plate is also a slightly different shape. The HP base is more of a rectangle where the Ergotron is thicker the further it goes back. I don't know if this gives a bit more support or not. Perhaps the biggest difference, other than the color, that most won't notice is that the HP version only comes with a 1 year warranty where the Ergotron comes with a 5 year warranty. Since this is a mechanical device it might be worth the few bucks more to get the Ergotron over the HP. Shopping around the price difference between the two is about 30 bucks. So one has to determine if the benefits of the Ergotron are worth that additional cost. Though if one is on a tight budget then the HP version is the best you can get for the price. Btw, both the HP and Ergotron LX arms are able to hold larger than 24" monitors so long as they weigh less than 20lbs. Though I wouldn't use them for monitors larger than 28" because you'll have limited height adjustment because of the larger screen size.
