    Well I was at Sam's Club yesterday, and I got to try out one of the new 3D TVs.

    I was impressed with it, but the glasses took batteries so I know that they were shutter glasses.

    I guess there isn't one like the PC 3D monitors that are really dual screens inside. That take the 3D glasses like in the movie theater yet.

    Anyone know when those that don't work with sutter glasses will hit the market?






    Me and the boy want to start setting money aside each month till we can get a 60'' one.

    What you are after are "passive" polarised 3D screens (which use the same cirular polarised glasses as the cinemas). I have one by zalman as a 3D gaming monitor - TV wise LG makes one for sale in the UK - the LG 47LD950 is the only passive polarised screen out there at the moment link

    You did mention that you thought that the 3D screens like in the cinema have 2 screens in them - there were a few screens like that out a few years ago but they were awful so i doubt we will be seeing them again. The next thing coming are glasses free 3D TVs using parralex technology which is the same idea as the holograms you get in cereal boxes but we won't be seeing good versions of those for a good few years.

    See the one with the 2 screens in them was the one I really liked for the PC> I have seen theZalmen also which was really kool too.


    I wonder how the passive" polarised 3D screens work them if they are not running dual sreens.

    Also I guess you can turn this feature on and off if you want it or not.

    The passive screens have alternating polarisation per horizontal line of pixels (this is fixed polarisation - a film is applied to the screen in the factory which achieves this)- so lines 0,2,4,6,8 etc are clockwise polarised and lines 1,3,5,7,9 etc are all counter-clockwise polarised. This means that on a 1080 screen each eye will only get 540 horizontal lines of pixels (as you can't see the pixels which are polarised the other way to what the glasses let you see) - but in your brain you still get a HD image as unless you're a one-eyed pirate then your brain combines the 2 images at once.

    As with ALL 3D TVs you only see a 3D image if the source is in 3D and/or you have 3D enabled - any 3D TV can do 2D without you being able to notice anything different to a 2D TV- plus you only need to wear the glasses to watch 3D content.

    They should encode anything to be in 3d tho correct? If that isn't the case yet; then I will wait a few years for one.

    Cause I know on PC, with some of the 3d monitors you can turn anything into 3d. Example: I remember watching 3dmark 06 in 3d, and that was really really kool.

    I know that you have to have the glasses, but at times I think this would be really kool to have.

    Some of the active shutter glasses have built-in 2D to 3D conversion but it isn't that great from what i've seen (not in this first generation of 3D TVs anyway). Personally I'd wait for the technology to improve (maybe next year - really it's best to see for yourself in a store with non-demo videos playing specially selected content) or for more proper 3D content to watch (we have what - 2 3D blurays out at the moment?)

    That screen uses parralex technology - which has some "sweet spots" you have to be sitting in with very precise angles to the TV to be able to get a 3D effect. We will be using this tech eventually (unless something new comes along) but at the moment it isn't good enough (and will be expensive).
    DaMulta and Conflict0s say thanks.

    I wonder if they will roll a bunch of them right before X-Mass, and your right about seeing it in person.

    Around X-mass always seems the best time to buy a TV, and would be around the time I could pay in cash for one.

    Thanks human-error

    Im still not confident to jump on this bandwagon... its come around a few times before and never caught on. So unless these tv's dont have a huge price premium i dont see the 3d fad lasting long enough to make a purchase worthwhile
