First, you aren't limited to one sweet spot with this TV,
there are nine. As you move around the screen in a semi-circle, the picture
pops in and out of 3D, akin to pulling a lens in and out of focus. If you're
not in a sweet spot, the picture doesn't completely blur and fuzz out. It just
flattens out into 2D.
On Vizio's Prototype, the picture is considerably less sharp
than on other high-definition or 3D displays. On-screen lines and fuzziness are
pretty noticeable, and the 3D effect doesn't always pop like you'd expect it
to.
But Vizio had something genuinely novel on display, 3D video
that can be viewed without glasses.
