Secondary Display Video Player 

Media player that displays the movie on the secondary screen while being controlled from the primary one. Additional features include playlist support and keyboard shortcuts controls.

Secondary Display Video Player is a multimedia player for dual display setups.

Control the playback on one display and play at full screen on the other display.

As nVidia dropped support for secondary display full screen overlay support from GF8xxx and up, users will find this application as a work-around to watch videos at full screen on the secondary display, if connected through HDMI, HD videos can be played at full screen and resolution.
