3D - 2

Do you need an 3d tv if you have a 3d bluray and 3d glasses?

If so why? Doesn’t the electronic 3D glasses interface with the 3D Bluray player? In other words, doesn’t the 3D Bluray operate the glasses? Is there a 3D ready kit coming to turn regular HD LCD tv’s into 3D LCD tv’s?

1. You need all three and there is no way that you would have the glasses and not the TV. You need active shutter glasses that are powered, and are synced to a TV. Those glasses you get at the movies (polarized) or the two color red/blue style (anaglyph) won't work. I've only seen updates or kits for TVs that were originally sold as '3D compatible' like the some DLP TVs sold about 2-3 years ago. Making a kit for regular TVs isn't as simple as making some box to sync the glasses because even if you make such a box, it doesn't mean the TV screen is capable of keeping up with the refresh rate needed which is 480hz for most sets, or 240 per eye. And no the blu ray doesn't sync the image, the TV does. The reason it's that way is that if you synced at the player, the unit does not know how much delay the TV has and the that can cause all kinds of other problems. Bottom line, you need a new TV that's labeled as 3D with the ability to sync the glasses, you need the active shutter glasses, and a new blu ray player labeled as 3D HDMI 1.4, and you need a HDMI cable that meets the 1.4 spec, and finally, a proper blu ray, not the small handful of movies that are labeled 3D and use the 2 color glasses.
