The Marmitek Gigaview 821 HDMI extender wirelessly transmits the signal from a digital TV receiver, media player or Blu-ray player to a TV, without requiring additional cabling for the second screen. It supports Full HD and 3D, and the HDMI signal is uncompressed, so there is no transmission delay. Its range is sufficient for devices in the same or an adjacent room.

It can be used for gaming on a large screen or for transmitting a signal to a ceiling-mounted projector.
