# 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

This is using 60fps video
Code:
```Millisecond/Hz=Millisecond
1000 / 59.9400599    = 16.6833333 Milliseconds
```
This is using 120fps video
Code:
```Millisecond/Hz=Millisecond
1000 / 119.88012 = 8.34166666 Milliseconds
```
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
Code:
```Millisecond/Hz=Millisecond
1000 / 71.9280719 = 13.9027778 Milliseconds
```
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.

60HZ TV'S are being fazed out, I bet buy the end of next year no one will be making 60hz tv's.
I don't know why anyone would really be willing to pay extra for 3D. I mean you still have to wear glasses and don't think its even all that good. I certainly would want to watch anything in 3D at my house but thats just me.
Why would I care about 3D or 240hz again?

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.
I have read that some 120Hz and possibly 240Hz TVs cause a weird "motion blur" to movies shot in 60Hz because they are essentially making up every other picture data. For example there was an article about Vudu streaming on an LG 120Hz TV recently.

Is this a common phenomenon to 120Hz tvs and all 60Hz sources? Sorry I have been out of the "TV" market for a few years and am trying to figure out if the higher Hz is worth it. Will you see the same problem on Blu-rays?

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.

Not to mention mostly everyone else, if HT enthusiast don't care already I don't think this is going to be as big as some think.
