I was very disappointed to learn that this monitor cannot be mounted on a monitor arm without a proprietary VESA adapter, which isn't included. You can't just buy one as they are non-standard. The monitor itself is ok, but the misleading description on the website and in-store staff member's complete lack of care when this is brought to their attention combine to leave you feeling pretty cheated. I now have a monitor arm that I can't use and a monitor with an enormous stand taking up space on my son's desk.
