3D - 2

Is a special tv needed to view 3d movies?

I have an LCD HDTV and I noticed comcast had a 3D Movie available. I watched part of it and noticed the distorted image that should make a 3d object, but when I tried my 3d glasses I seen no difference. I know it's not a problem with my eyes since I seen 3d in theaters recently before. I just want to know if a tv needs to support it or whatever. Thanks!

1. no. you have been thinking of everything that could be causing a problem except for one. the one thing you didn't ask about is the glasses! there are different types of 3d glasses today if you would believe it. the olden style with blue and red and the new ones which look kinda grayish. don't know where you would get 3d glasses, where did u get yours? if you really cant figure it out just call the provider and ask them about the issue. i am sure of you had problems some other would too and they would have a solution.
2. It depends on the type of technology being used. If it's simple RED/BLUE lenses it will work on any display device. If they are LCD shutter glasses they won't work on anything other than a 50HZ interlaced CRT ( Cathode ray tube, or the big fat heavy TV's) Reason #1 The glasses will have polarizing filters which conflict with the already polarized light coming out of your display #2 the fastest LCD displays can't even change state completely 25 a second which is needed for them to work. #3.. It's a progressive display device..
