LED display Definition
What you ought to do is take that huge new Light-emitting Diode display and use it as a real computer system monitor, without as a stand alone presentation show.
From that which you explain (and without a make and model number, plus your limited information associated with the circumstance it is difficult to do more than guess) the LED display has actually it really is very own operating system, and it's very own news people. You may be playing the music using media players which can be installed on that operating-system, as well as do not provide a visualization option like you would discover with VLC or Microsoft windows Media athlete, or Winamp, an such like.
Now. If you decide to connect these big LED displays to a computer and use all of them as a monitor, then you might undoubtedly drag a person screen onto them (or simply clone the show, and make both the primary computer system monitor together with huge Light-emitting Diode screen show the same thing) and possess a visualization screen this way.
Otherwise you need certainly to discover what OS is running on those TVs, and exercise just what computer software you can easily put in.
Unless, there are details you will be making out that would change the whole aspect of the concern itself.
EDIT therefore, because you can't link the screen as a monitor, therefore just displays the output generated because of the LED Vision software, and therefore computer software need videos... you can use any ipod you want that creates visualizations, make it show complete screen, have fun with the music you want, use computer software like CamStudio in order to make a video regarding the desktop (thus getting the visualization and songs synced together) and play THAT movie through the LED Vision computer software.
