Most new computers and all older computers have a VGA connection for carrying video signals to a monitor. While some computers have switched over to DVI or one of the other new video connection formats for their video connection, VGA is still considered standard. While they would function in the home, there’s a good possibility that the frequency they transmit on would cause interference with other devices. They are really not intended for home theatre use and some models are actually prohibited from use in homes. Wireless VGA adapters are made to accommodate this need. There are times when it would be much more convenient for the presenter to have their computer with them, while the presentation is run on a HDTV across the room.
