From examining it.. I don't think that item i linked will work, I will just go with the item being sold on ebay. I wish I didnt have to shell out another $50 to mount these dual monitors after already buying a mounting system. Dell you suck!
Totally agree - what on earth. Why do I have to spend this extra money on an industry expected standard. Even the monitor I bought in 2009 with far less bells and whistles has this basic feature.
