True or False? This is what my buddy was telling me, but i have no way to verify this info. Anybody know for sure. I find it hard to believe that a "3d TV" is just a marketing initiative.<p>Also side question, does anyone know if Google TV boxes come with Component, HDMI, or Cable wire connections.
To display 60hz stereo images, you need a 120hz image and synchronized shutter glasses. Each frame is shown twice, once to the left eye and once to the right. These are interleaved in time and synchronized with the shutters on the glasses that alternately close the left and right eye. To display stereo images, you not only need a 120hz display device, you also need a way to synchronize the glasses with the image. There are some methods that patch into the video stream and use the vsync there, there are some that plug into the television itself and are triggered by actual frame changes. Note that progressive scan LCDs tend to be terrible for stereo, because not all of the image updates at once, and thus each eye sees some of the image meant for the other eye (and you get blurring and the stereo illusion breaks).
Not exactly.<p>For a computer monitor to be compatible with Nvidia's 3D shutter glasses, all it needs is for it to be 120Hz. The connected computer has a USB dongle which the 3D glasses sync with. For a TV to really 3D capable, it has to have the dongle built in, and be able to interpret a 3D signal (HDMI 1.4a[1]). What confuses the issue is that most TV's and computer monitors these days have both HDMI and DVI ports on them.<p>[1] <a href="http://www.hdmi.org/press/press_release.aspx?prid=120" rel="nofollow">http://www.hdmi.org/press/press_release.aspx?prid=120</a>
Do you mind if I side-track a little and ask people's opinion of 3D in general?<p>I've seen two movies in 3D in the past year - Avatar and Toy Story 3. While Avatar was fun, and Toy Story 3 exception, I didn't feel that the 3D really added much to the experience. In particular, the colour for Toy Story 3 seemed dimmer than normal. I also where glasses, so I sometimes had reflections obscuring the picture.<p>I understand that 3D is being hyped as the next big thing to get after a big flatscreen TV, so I'd be interested to hear what people here think of it.
