3D TV

Visit to any electronic shop TV section and not checking the latest 3D tv is just not possible. With every other movie coming out in 3D from Hollywood to Bollywood 3D has become a buzz.
So is it the time to buy 3D TV,lets ponder on these points

3D TV technology:
If you watched the 3D movies in theater maybe 10-15 years back 3D tech works on the same principle still now. Video filmed by two separate cameras with slight different angle are projected onto the screen and audience wears the glasses that make sure that right and left eye sees the corresponding images.3D TVs work on the same principle with two different types of TV's in market
   1. Active 3D:
   In this case the Glasses have the shutter mechanism to make the right and left eye see the  
   corresponding frames. 3D glasses are heavy and expensive( Rs 3000), you need to get used to
   them. However the Active 3D TV is less expensive as compared to Passive 3D. Now-days 
  companies are manufacturing less heavy and comfortable 3D Glasses.
   2. Passive 3D:
   TV itself has all the mechanism and hence the polarized glasses are very comfortable and quite
   cheap( rs 100 to 800). Now-days Passive 3D TVs are most popular, however they tend to be
   expensive as compared to Active. Here is comparison between these two
   1. Passive glasses are easier to use and wear, also cheaper.
   2. Active glasses flicker, this might be irritating and gives headache sometimes.
   3. Passive 3D result in lower resolution as compared to Active 3D.
   4. Active 3D tv requires good refresh rates hence Plasma with Active 3D is best, otherwise for 
       LCD/LED go for Passive 3D.
   5. Experts says Active 3D is better quality images then passive 3D apart from the glass issue, but I
       didn't notice any major difference.

3D Content: 
Now-days all the major Hollywood movies come out in 3D and they are really treat for your eyes. Bollywood too has focused its attention on 3D. As far as 3D TV channels are concerned there are no 3D TV channels in India apart form the TEST 3D Channel on Videocon D2H which has almost useless programming and 3D quality.If you decide to buy 3D Blue-ray that could be pretty heavy(Rs 1200 min) on your pocket, so finally there is nothing left that you can watch on your 3D TV.
Don't worry there is option get a 3D TV which can play DIVX or other movie types from a USB device, so you can download a loads of 3D movies/ other stuff from internet and watch.YouTube also host lot of 3D videos,also sites like "thepiratebay" have 3D movies which you can watch.

Theater like experience:
  Watching 3D movies in theater is a different experience than watching it on your 3D TV. Theater screen size is a huge plus point as the 3D pop out effect directly depends on it, so remember 3D pop-out will depend on your TV size. Now days 3D movies focus more on making the user feel as if he is watching through a window i.e depth rather than all the things popping out. IF you seen Avaatar there is hardly any seen that has a pop out effect, throughout the movie you feel the depth and window effect.So 3D depth again depends on screen size and is limited to size of 3D TV. If  you rate the Theater experience of 3D has 100, Home 3D TV experience can range between 80-60% depending upon size of TV.

Bottom-line:
3D TV is new tech and it will take its time to mature, so if you planning to buy a new LED/PLASMA TV and if you can go for 3D feature without being heavy on your pocket go for it.

Notes:
1. Animation in 3D always looks gr8, do check some non animated content on 3D TV before buying.
2. Make sure your 3D TV can play USB 3D Content and get  yourself a highs peed (at-least 1mbps) unlimited internet connection so that you can get lot of good 3D content without spending heavily for it.
3. 3D doesn't mean just POP-OUT effect, it nowadays means having the experience of depth and watching through a window.
4. Demo clips that you watch on 3D TV displayed in showroom have excessive pop-outs and depth experience hence don't get disappointed if you don't feel the same while watching a 3D movie or regular 3D content.
5. 2D-3D conversion is useless stuff simply ignore it.
6. LG Cinema 3D is really good, also Samsung, Panasonic and sony also have some good 3D tv models which can be a good option.
