In general, techniques are described for preparing video data in accordance with a wireless display protocol. For example, a portable device comprising a module to store video data, a wireless display host module and a wireless interface may implement the techniques of this disclosure. The wireless display host module determines one or more display parameters of a three-dimensional (3D) display device external from the portable device and prepares the video data to generate 3D video data based on the determined display parameters. The wireless interface then wirelessly transmits the 3D video data to the external 3D display device. In this way, a portable device implements the techniques to prepare video data in accordance with a wireless display protocol.
