Ok, so removing the stand is possible but you have to be extremely careful not damage the monitor. For some reason the screws you see from the bottom (underneath) of the stand are not the only ones that hold the stand attached to the stand (even though there are 6 of them....) There is another screw on the backside of the L shaped rotating bracket. It connects the plastic stand and the monitor itself.
I just ordered a mounting bracket to put this up on the wall, so I guess I'll get to experience this fun for myself.
I bought one to VESA mount and managed to get the plastic stand separated. The metal tilt mechanism is still attached to the monitor and I'd like to remove that, also. Were you able to remove that portion? If so... how?
