The protrusions of the metal inserts on the underside of this brace are not roughly perpendicular to the underside, they are bent too far. I used a screwdriver to bend them just over 90 degrees. After that he stood in place as the base of the monitor should be. I blame HP for requiring an extra part for such a generic feature. If you're not ready or never plan on moving this monitor, I'd look elsewhere.
