Can someone provide instructions on how to remove the pedastal arm from the L2550pwD 22" monitor? I want to use the VESA screws to mount it to a dual monitor stand. The manual online from Lenovo is NOT for the same model. I called support and they could not provide the correct manual either....saying: "we can only provide what is online." I can provide a pic via email of my specific monitor. Any help would GREATLY be appreciated.
