I'm not sure that is true Slewis, I think that lg make / are about to sell "passive" 3d tv's i.e not full hd, these use the same glasses as you get in the cinema, I had a demo in a local retail centre with some game footage and the glassed seemed the same to me.

maybe somebody could confirm or otherwise, but they certainly were not the powered "active" type I have demoed with samsung / panasonic sets.

Absolutely correct, LG are marketing a set that uses polarized glasses. Sony, Samsung and Panasonic use active type glasses and none of them are compatible with each others system!

A good reason to stay well clear of 3D

That's not entirely correct, mostly they've just swapped the left and right sides over, so if you wear the glasses upside down it works fine!

Not particularly practical, but probably no more uncomfortable than the Panasonic glasses I tried the other day...

simoncar:Hi does anyone know if you can use the glasses you have in the cinema with 3D tvs in the home
Another point to know is that next time you're at the cinema with 3D glasses on, tilt your head left or right and you should lose the 3D effect because of the way polarisation works. With the Sony, Samsung and Panasonic system, you can lie on your sofa and not have that happen.

No, it is the other way around.

In the cinema you can tilt your head without loosing the 3D effect. The same is true on the Panasonic plasma (and I assume also for the Samsung plasma).
On LCD sets the two filters (from the screen and the glasses) will interact, and at a 90 degree angle the picture is completely gone.

A couple of side points. With the passive TV sets you lose have the resolution as it is done on a line by line basis (odd lines for the left eye, even lines for the right eye) - one of the main reasons most manufacturers have gone for active shutter glasses.

TKratz is correct about tilting your head for the LCD/LED TVs - the shutter effect is lost quite quickly - though it's worth pointing out that the 3D effect is set for someone looking at the screen directly and not with their head tilted! I think watching with your head tilted would be a good way to give yourself a headache/eye strain.

You sure? I had a demo in a Currys recently of a C7000 (I think) and the guy selling it told me that. I even tilted my head and noticed no affect to the picture. That said I've not been to the cinema since to try out the polarisation head tilt to verify this.

u have to tilt your head a lot - around 60 degress or so I'd say to notice it, and yes at 90` u see a totally black screen. But u dont watch tv like that.

Oh ok, I'll give it a go when I get mine. I must've picked the guy in the shop up wrong.

Tell you what is cool - at least it works with the Sony specs - put them on and then look at a metallic paint job on a car and it looks pearlescent :). I'm not sure you want to drive with them on though - I don't think you'd get away with "but they enhance my 3D depth perception officer".
