My interest is in the angle the cable would have to be bent when the arm is in its lowest position. It appears from the iLift spec sheet that the cable would have to bend instantly at a 45 degree angle. From looking at the cable at the back of the 30" display at the dealer, the cable won't bend with that small of a radius.
Also, I wouldn't want to bend it that sharply anyway for fear it would eventually fatigue and break one of the wires in the cable. That happened to me once some years ago when I used a desktop display attached to a laptop portable. Using it that way over a year or so, moving the cable every day, eventually broke one of the small wires in the cable to the display. (Not an Apple display)
That is why I was wondering if anyone had any practical experience with this arm and display. I was wondering if it was more practical to clip the cable to the arm, rather than install it internally to the arm, avoiding the sharp angle.
