A coupler and a system are provided for mounting panels, such as a plurality of display tiles. According to an embodiment, the system includes a mount sheet having a plurality of mounting positions, a plurality of chassis having at least one locating feature and at least one magnetic coupler on one side and at least one magnet on an opposite side. The locating features on one side of the chassis are adapted to locate a locating feature on at least one display tile. The magnetic couplers on one side of the chassis are adapted to magnetically couple at least one magnetic coupler on a display tile. The magnet or magnets on an opposite side are adapted to magnetically couple the mount sheet in one of the mounting positions.
