Can't fit LG monitor back in box

Samsung ships this monitor in two flavors according to my converstation with L2 tech support, the stand that rotates and the one that does not. According to L2, I have the one that supposedly does not, as the one that does says so on the outer carton. But the stand has a round mount that attaches to a 200 x100 mounting hole bracket that attaches to the back of the monitor. But out of the box even with about 20 pounds of force it only rotates about 3 degrees clockwise or counter clockwise and then hits a hard stop (like a pin) and there is no release button. You cannot rotate it....yet. So here is the trick. You need to remove the 4 screws that hold the mount to the back of the monitor and remove it from the mount. Now when you look at the rotate mechanism you we see a phillips head lock screw....remove it. Remount the monitor and now it will rotate as it was designed to do. My guess is that when Samsung sells this monitor with the "optional rotate" feature, they get a few more bucks for it! Hope this helps...BBRAND.
