I hesitated between this arm and the D775BLACKPLUS, because the "PLUS" can carry screens up to 49 inches and this arm "only" supports screens up to 32 inches. On the other hand, I see it happening soon that I'm going to buy a new monitor and this arm is perfectly adequate for my current Dell 27-inch monitor. The difference between these 2 arms is, as far as I have been able to discover, only in the carrying capacity, 16 kilos vs 18 kilos.
I bought this arm as a Second Chance and it was considerably cheaper, making the price comparable to many other computer stores. The reason for this was probably because one of the Allen screws in the lower bracket was mounted inside out and therefore could not be attached to the foot. But after a little bit of fiddling, the screw was out and the arm could easily be put together. It is literally clicking together and tightening a screw with the included tool (you still need a Phillips screwdriver). Attaching the foot to the desktop is also easy, in my case this was done by tightening 1 bolt and clamping the foot in this way
A note about the type of clamps for the foot: on the Coolblue website, the 2nd image shows another clamp that needs to be tightened with 2 screws, in addition to the images of the clamps actually supplied. The manual available on the Coolblue website also provides instructions on this (clamp with 2 bolts). In that regard, you have to rely on the manual that comes with the D775BLACKPLUS. Maybe Newstar also has this arm in circulation with this other (old?) clamp, but I certainly didn't have this one. By the way, no further problem, only with that other clamp you can clamp the foot on table tops up to 80 mm, with the clamp I have it can "only" up to 45 mm. With thicker desktops you will have to drill a hole to be able to use the other clamp supplied. What can be useful is that a holder is supplied that you place on the back of the foot, in which you can place the 2 Allen keys. If you ever need to remove/re-adjust the bracket, you'll have them right at hand.
Adjusting the bracket is also easy, after having hung the monitor on the bracket, it is a matter of tightening the bolts with the supplied Allen key. Removing the bottom cap from the cable tray seems a bit tricky, because it's plastic, but with a little force it comes off easily. The top plastic cover is secured with a screw, so it takes a little more work. I have 4 cables that have to go in the gutter (power supply, DVI, DISplayport and USB upstream). It doesn't help that the DVI cable is quite thick, but in my case 4 cables is really the maximum that fits. Putting the caps back on was the most work in the end, but once they are in place, they do stay put.
Moving the screen is wonderfully easy and it also cleans up the desktop because I no longer have that huge foot. What I was concerned about was whether the monitor wouldn't move further from the wall than it was on the base. This turned out to be unfounded, because the bracket can simply be put tightly against the wall and can therefore be placed a little further away from me. I should have bought this thing much sooner for that matter, I'm very happy with it!
