3D doe's not work for every one, well it does not work for me nothing pops out of the tv and the picture is fuzzy.

I think you have to have a good eye sight. My right eye is a lazy eye. I have to wear glasses. I can see more out of my left then my right eye.

A place in Scarbrough on the south bay use to have amazing 3D holograms picture's, you had pay to go in and it was only a small room, I had no problems see them, you didn't need to use special coloured glasses to look at them..That place is closed down, I can not remember name of it.

Does any one have problems whatching 3D Films.

Have you tried 3D in the cinema, how does it look there ?

At the moment, Avator is back on the big screen, if you have never seen a 3D moview its worth checking out just for the technical aspect.

I wouldn't rearrange my living room to sit directly in front of a screen so bit of a non starter for me.

In the cinema I find I get bored and can't wait to get rid of the glasses. so much so that it ruins the film, the effect works but there is a drop in picture quality. Almost as if I can't focus properly, which probably explains the boredom.

As for the dodgy home dvd version of old, it just renders the whole thing unwatchable as I can't make out the picture let alone the effects. So I think perhaps good eye sight is a must. I need my glasses on to watch HD after all lol

Not a con though as it seems to work for some and plenty seem to enjoy it.

You don't have to sit in front of the TV for an active 3D system, it works no problem off centre.

As for the cinema, there is no way for the effect to work without the glasses and off course the picture is going to be look out of focus, because its designed to be viewed with the glasses.

As for HD, I do agree that eye sight plays a part but not as much as source, display and distance from screen. My dad is registered blind, he has very little vision and he can notice the difference between SD and HD. Even though he has a HD set now (he wanted a large screen size due to his vision being so poor so in this day and age tha meant going HD) there is no way its worth paying for any of the subscription HD channels.

Its known that some people who have had a lazy eye actually lose 3d vision competely even in their daily life. The brain can't handle the lazy eyes mismatched signal and eventaully just shuts it off/ignores its input. It was thought this was permanent, but in recent times they've shown that through therapy 3d vision can be restored. Op could be suffering from this.

"When Sue Barry used to see snow falling, it would appear as if the snow were falling in one flat sheet in front of her.

"I did not feel like I was part of the snowfall but I was looking in on the snowfall," she tells Fresh Air's Terry Gross.

Barry, a neurobiologist, had been cross-eyed since early infancy. Though she had operations as a young child to correct her eyes' appearance, they still sent conflicting messages to her brain. As a result, she viewed the world in a flat plane and had no stereoscopic 3-D vision............."

Pocatellp - looks like lazy eye could be a problem,

Even if it turns out that you do have a problem with your two-eyed vision, don't worry! Less than five percent of the population have severe visual disabilities which make seeing in 3D difficult or impossible. This group includes those who have lost an eye or very few of those with medical diagnoses of amblyopia (lazy eye) or strabismus (eye turns -- "crossed eyes" or "wandering eyes"). In MOST cases, two-eyed vision (binocular vision) can be improved with supervised vision therapy.

I have no problem whatsoever wherever I sit in my living room, you really do not need to be dead centre in line or anything.
Don't compare it to the cinema though, some of the 3D material I have seen there can look poor. From the TV in HD it looks very good indeed

A'hem! There wouldn't be much point in watching at the cinema without the glasses would there? It looks slightly blurry out of focus with the glasses. Which is why I get bored and tend to give up on it. To be fair since getting HD I have noticed just how poor picture quality is at the cinema. Still the free nachos are good.

Interesting that you no longer need to be centred to the TV though. As I stopped reading about the Sky offering when all the talk was of being dead centre. So it might be worth looking in to again.

i was at best buy yesterday and got confused by the 3d tv's. at first it seemed like they were not working, but it was because i had to "switch on" the glasses. this then gave a much better 3d effect than ive ever had at the cinema with passive glasses.

what do the active glasses do that is different?

I was wondering if you wear specticles and wear the 3D glasses on top. I noticed a difference when I wear corrective glasses and when I have not had to.

Also I wonder if there is a technical problem with the screen setup, from what I have experianced at two different cinemas, the picture should definately not be fuzzy, strange.

The system between cinema and home is different.

In the cinema they use a polarised filters in front of two projectors (one projector/filter for right eye, one for left). So the glasses you wear have the appropiate filter for left and right eye. So both left and right pictures are on the screen at the same time, The system works best when you sit upright and roughly in front of the screen, not a problem in the cinema. This is also sorta the system they have been using at pubs.

Home 3d, they show an alternating left and right picture and the glasses are synced to the picture so when the TV displays a left picture, a electronic shutter (which is why batteries are required) blocks the right eye and vice versa. So at any one time you have either left or a right picture on the screen. This happens very quickly and its enough to trick your brain into thinking there is only one image. Viewing angle is a lot better then cinema and you can watch the picture lying on your side.

BTW the glasses are designed so that unless you are looking at the screen, they should switch off automatically to save battery.

I found, when I saw Avatar in 3d at the cinema, that often what you're looking at, and what the director wanted you to look at aren't the same (which is probably the real reason behind boredom - lack of interest). In those instances some parts of the 3d image can, indeed, look out of focus. The depth of field simply wasn't deep (or close) enough.

How many times has the movie industry tried to resurrect 3D. About 60 years worth.
It ain't never gonna become the norm. Avoid it. It's just another fad.

It depends, the circular polarized filters don't require you hold your head level.
In the end its about the same, the polarized filters cut light, as do the shutter glasses..which actually cut light even more as half the time your one eye is completely in the dark.
