240Hz tv's will have to be the same cost as 60Hz tv's for 3D blu ray and tv to take

Blu Ray tv is $2300.00
Same tv but 60Hz is $1500

From the sticky I made in a different forum: link

This is using 60fps video
This is using 120fps video
If we take the 144fps of digital theater 3D, and divide that by two (one for each eye), we have the milliseconds number that people see in the theaters when watching 3D. This is the standard that must be met or exceeded when talking about quality 3D.
If the milliseconds of the video is slower than this than the quality of the 3D is not as good as the one seen in the movie Theater when watching movies like Disney's Up.

This is the milliseconds standard of excellence
As we can see, the 120fps is faster than the standard of excellence used by Real D theater 3D. So the quality is very good 3D.

If we have a 240Hz tv, the tv can output 120fps 3D per eye when using shutter glasses. The milliseconds speed of this 120fps video is so fast there would be no "flicker fusion threshold artifact/jerkiness".

The reason the tv would need to accomodate 60fps video is for sports tv, namely the nba which shoots video at 60fps.
If the nba wanted to show 3D video at 60fps a true 240Hz tv could do this properly whereas a 120Hz or 60Hz tv could not.

The price of a 60Hz tv must be met by the 240Hz tv and not only that but the 240Hz tv must be made in great enough quantity it saturates the tv market, then 3D 240Hz tv would be at a premium that would be within reach of the average consumer.

Right now at 240Hz lcd tv is 2300.00, and a 60Hz tv with the same features is 1500.00.
This is too much since the cheap 3D tv's need to be 240Hz as well, so the tv necessary for proper 3D is at a acceptable premium when compared to regular 240hz tv's.
What does this mean, what am I saying: that tv manufactures need to abandone 120Hz and 60Hz tv's and move to 240Hz tv's and this means not milking the market for 60hz and 120Hz tv's.
This is a Necessary expense and it will be the Only thing to nsure the future sucess of 3D tv.

So that watching movies or blu ray documentaries is like seeing it through a window rather than the regular way it is now seen with 2D.

Perfect 3D Tv/BluRay is the same as looking out your window and looking around outside.

There is different quality from parallax value though. Meaning the greater the screen size the greater the window to see through is and so the 3D experience is greater.
A smaller screen will, or rather Should give the same sensation as looking through a window but not so immersed as looking at a big fish at the aquarium.

There is two technologies, Max:
Pulldown
Interpolation

Pulldown doesn't create new information, It repeats a single frame a number of times before showing the next frame.

Interpolation creates new information in the picture that wasn't in the picture before, causing what some people call "Soap Opera" quality.

3D Blu ray doesn't use interpolation from what info they have provided.
3D bluray uses pulldown.
