A system comprising a switching device linked to a common display screen and including a wireless receiver configured to receive content, the switching device configured to use the received content to drive the common display screen and a plurality of interface devices, each interface device including an interface housing, an interface device processor, a control button mounted within the housing and a plug linked to the housing via a cable, the plug receivable within a connection port of a computing device, a first interface device including a first device processor, a first plug and a first control button, the first processor configured to perform the steps of, with the first plug received in the connection port of the first computing device and first content presented on the first display screen while other content is presented on the common display screen, detecting selection of the first control button and, upon detecting selection of the first control button, causing a wireless transmission to the switching device, upon receiving the wireless transmission, the switching device presenting the content from the first computing device display screen on the common display screen.

A connecting structure for attaching a wall-mount fixture to an external portion of a display device includes a fastening member. The fastening member is integrally formed as a one-piece, unitary member. The fastening member includes a receiving part, and first and second bent parts that extend from the receiving part, the first bent part having a first end plate with a threaded hole, the second bent part having a second end plate with a screw insertion hole, the first and second end plates overlapping with respect to each other and facing with the receiving part. The receiving part is configured and arranged to receive a distal end of a screw that extends through the insertion hole of the second end plate and is screwed into the threaded hole of the first end plate such that the screw is prevented from being screwed beyond the receiving part.
