My wife and I have two of these excellent monitors, and I looked through the owner's manual for an answer to your question, but it didn't help. What I would suggest is to look at a monitor on display, and I'm sure a salesman would allow you to see the rear and even remove the stand mount, which takes about 5 seconds (it just snaps into place..
I don't know how the wall mount would attach, so I can't compare the way it would mount.
In reading on-line reviews, I found one where a customer is using a VESA mount, so it is apparently possible, but please look at one in a store display, since it is not mentioned in the owner's manual.
I wish I could be of more help.
