A:Answer To the best of my knowledge, this mount is not suited for a corner mount, unless you install some sort of cross-brace and thus create a flat surface to which the mount could be attached. My recommendation would be to consider a pole mount, or other type of mount that is specifically designed for corners. Installation costs vary, and keep in mind that most of the time, you will need an electrician to install an outlet that is hidden by the TV itself. It is for this reason that most installers of TV mounts seem to be electricians. You're probably looking at $300-400 to have an electrician install a TV mount as well as an outlet, and maybe even more if the labor involved with adding an outlet is excessive.
