I'm not trying to be mean. But you don't own a "3d tv"; you own a 2d, stereoscopic television that marketers *called* 3D, although it clearly isn't anything of the sort.
A 3d display will allow you to see behind the actors. If you move, your point of view will shift. If someone moves closer, it won't be the camera that has to re-focus to follow, it will be your eyes, because the objects in the display will actually be nearer or further away. You'll be able to look down on a tennis match on your display as if from the sky, from any side of the court, or up at it from (the player's) shoe-level. Your true 3d display will not take up a flat surface. It will take up an 3-d volume and within that volume, truly volumetric objects will seem to exist.
What you have right now is basically a ViewMaster that changes images really fast. It's not 3d.
