Just a quick info burst for those interested in 3d tv.

The main type of 3d tv will be using what they call active shutter.
This is done by 2 images that are the same (1 behind the other) being shown at the same time and special glasses with one eye or lens having horizontal shutters and the other vertical that will be controlled by the tv (via infrared) to partially block some of the images to trick the eye and mind into thinking the image is 3 dimensional. For this process to work smoothly and acheive HD quality the tv will atleast have to be 120 hertz (normally 60 on normal sets but there's 2 images as said before.)

As the glasses and tv will use infrared like a remote the glasses will be unique to each brand however a range of generic glasses have already been produced by monster. 3d bluray players have already been produced and panasonic, Sony, samsung and lg will have a range out from this month and at latest June. There are 3 other types of 3d available and another variant will be used for pubs and commercial use that will be cheaper to produce but not as accurate or produce the quality if image as active shutter.
I just can't remember what it's called lol

basic info but feel free to google 3d tv technology and expand ur mind.

Cheers

Also there may be an eye strain issue that has not been fully researched causing problems for migraine sufferers like me. Now I am not sure if it affects all versions of 3D but I for one would like to know more.

I agree with the above. Tv technology us useing to many eye and mind bending tricks and there may be some health issues come out in the wash later down the line. Had a few folk mention migrants after using sub field driven tvs.

Ive been interested in this 3dtv for a while now but sceptical....the best 3d "feel" i have ever had was in the IMAX totally awesome but that is also a massive screen were talking 50 metres long and vertical so you are fully endorsed into the picture therefore making it more real.

No issues have ever been brought up with these 3d showing before and there glasses are standard £5 ones.

Anyone watch the footy on sky 3dtv at the weekend.....just looking for some feedback.
