I just purchased two Acer AL2216Wbd LCD displays for a great price and want to mount them on a dual display stand. The only problem is that the stand that attaches the screen to the base seems to be permanently attached. I don't see any screws to take it off and I don't want it sticking out from the bottom when the screen is mounted. Does anyone here have, or has had, one of these monitors, and do you know how to detach the stand? Thanks.
