About those monitors (model # ?), I have a similar model with that type of stand. Mine DO NOT have mounting holes/thread inserts in the rear to mount on the racks often seen and discussed here on ET. I can't see if those do but if your thinking of a rack mount, take a good look at that. Many times I believe they are returned because of this, then resold at a discount. GREAT DEAL!!
