    I've planned to buy one around Diwali time and have zeroed in on LG PK550 PLASMA-50inches costing around 63k and LG LED LE 5500-42 inches costing around 73k,had almost bought pk550 plasma but stopped from doing so after reading about various niggels(just like fiat cars!)like dancing green pixels and temporary image retension,PQ in both the mentioned TVs were great ::T ,better than the other brands.Presently I have a 42 rear projection Samsung TV and Iam extremely happy with it
    Do you guys have any idea?,any other Tv to go for in the above budgets,am not going for LCDs as in my view the images are very blurred,especially the fast moving ones like a heroine dancing in a song! ::D
    Any suggestions??

    Bala,

    My daughter has Samsung 32 LCD HD TV at Melbourne, which is very good. HD TV plus HD telecast result in excellent picture quality. I am fully satisfied with that. Please try that too before taking a decision. In fact, my son-in-law was recommending that I too take similar one here.

    I'm no expert in this and have not done any internet research as well but I think the only advantage of Plasma is that they are able to generate "black" color (greyscale rating or something?) better than LCDs. LEDs are newer technology and are the best.
    Plasma's are getting older. Even 3D LEDs have arrived.

    Also, 3D ready TVs from Sony and LG Infinia (really mouthwatering) will be much more affordable by next Diwali (Current price around 1.5-2lacs for 47" ::V ). Since you are more than happy with your current 42" projection TV, isn't it better to wait and upgrade to a much better product? These TVs also give free packages like a pair of 3D glasses of course, 3D Blue Ray player etc.
    I think that a 40" 3D LED TV <1 lac will be more VFM than current 42" LED at 75k today. But, I may be over enthusiastic in saying so.

    I would recommend anyone to stay away from 3D stuff for home as the technology is currently too primitive to watch continuously. There is a hell lot of difference watching a 3D movie in a theater for two hours and watching 3D TV at home continuously.

    Yeah, it is something I read recently while researching 3D vision technologies.
    Our brain uses some 7 cues for depth perception, don't remember all of them, but parallax, size, speed, texture, etc are some of them.
    Current 3D technologies use only parallax (stereo scope) for creating the depth perception. Fooling the brain with just one cue for a short time is ok, but long term exposure to this is reported to have negative effects which may manifest as headaches, etc.
    magnan and rs3sekar like this.

    Thanks. ::T
    I had no clue regarding the technology behind 3D LED TVs but surely this is a very valid point.
    More than the 3D technology, I was carried away by the design(these TVs have very little metal around the screen and it looks awesome. :)

    Thanks Raviji for the info,I shall give a try with Samsung lcd,when I did last time in a showroom,wasn't good at all.
    Paddle shifter,yes ,you are correct and that was why I didn't buy a flat pannel last diwali,went to the showroom but came back thinking that it would be very much cheaper this Diwali!,they get cheaper every year and if we keep on waiting,we would become too old to view Tv itself! ::D :lol:
    About 3D,slightly off topic,I have received a 3D viewing glass with the subscription copy of topgear magazine,what is it for??!! :confused (received a free DVD of casino royale too with the magazine)

    Yes sir, true. :) But I thought one more season can be passed if a far superior technology becomes much more affordable since you said that you are extremely happy with your current set up. :)
    But Royj has posted a very good post in explaining the main technology behind 3D LEDs.

    Wow! 3D glasses with topgear. But I doubt if they will work with normal displays. :confused

    They should work even on normal displays with movies specially encoded to support them. Since it came with Casino Royale DVD, I believe that version is created for viewing with these glasses. Usually they are blue/red glass commonly known as Anaglyphic Glasses and can even be made at home.
