I've just bought a new 3d television but I don't understand how it works. I have the 3d glasses that go with it but when I turn them on and switch the TV to 3d, it dosen't work. Do I have to have a blu ray player connected or a sky/virgin etc subscription to watch in 3d? I thought I could just watch normal television programs and dvd's in 3d. I'd really appreciate any help, I'd feel like an idiot having to go back to the shop to ask! Thanks :-)
Answer
You have to have a 3d blu-ray player and a 3d blu-ray disk with a movie in 3d on it.
See a 3d movie is actually 2 complete 2d movies on the screen at the same time. One 2d movie for your left eye only. One 2d movie for your right eye only. The job of the glasses is for the lens to block the movie for the other eye. Your left eye can not see the right eye movie, same for the right eye. If your eyes do see the other movie the 3d will not work.
To get these 2 movies the camera they film with has 2 lenses spaced apart like your eyes and film at the same time. Your right eye then sees the movie from the right lens. If they do conversion of a movie shot in 2d then they must make 2 movies for each eye using computer software, a very long process.
Because of the lens spacing when filming the double images on screen with both movies don't always match up. They often space apart to the left or right to make these images look far away or close up when you have the glasses on. If the left eye image is on the left side and the images are spaced relatively far apart it looks far behind the screen with glasses on. If the left eye image is on the right side, opposite of before, then it looks in front of the screen. If the double images over lap and look like one image, it looks screen distance. Again the further apart the images the further in front or behind the screen they look with glasses on. Just depends which direction the 2 images space apart.
So for powered glasses the 2 movies flash on screen very very fast as follows: left right left right left right left and so on. Then the lenses of the glasses open and close left right left right left right and so on. That way when the left lens is open, the left eye only sees the left eye movie.
So your source movie MUST be in 3d with the 2 2d movies for each eye. If you have a 3d blu-ray disk you MUST have a 3d blu-ray player that can read this extra information that a regular dvd or blue-ray disk does not have.
You will also need an HDMI cable to connect the player to your tv. The store manager can tell you which one you need.

Can I watch regular Blu-ray movies on a 3d tv?

I'm going to buy a Blu ray box set of a film series soon, and I know that I can watch regular Blu ray movies on 3D Blu-ray DVD player, but can I still watch these non-3D Blu ray movies (using a 3D Blu-ray DVD player) on a 3D TV? Please help me if you can.
Answer
Yes. A 3DTV is just an ordinary HDTV, with nothing really different about the screen.
Active shutter 3DTV's, (like Sony & Samsung), have fast enough refresh rates, (at least 120hz), for the left & right angles on a Blu-ray 3D to be flickered back & forth with smooth motion.
Passive 3DTV's, (like LG & Vizio), shine the light from the screen in 2 different polaritys for both eyes. Keep in mind, though, that your 2D Blu-ray's won't BE in 3D. Some 3DTV's have so-called 3D 'conversion' features, but there is NO TV that can do this effectively on-the-fly.
