Hi everyone my tv is on its last legs i'm gonna need to get a new one soon i was thinking about getting a 3d tv i have some questions
1st do any of the larger tvs 50 inch plus have any built in blu ray 3d players
2nd I've seen that some of the glasses need batteries why is this and do i need to have them glasses or could I use batteryless ones
3rd hypothetically if i was to download 3d film form a torrent website would i be able to put this on a usb stick and play it like that

Active glasses have LCD shutters built in a need to sync to the TV. Passive glasses are polarised so they work like you local cinema :)

3rd you can download Side By Side films and they will play back fine in 3D off a USB stick. You can also take 3D pictures with a camera

You have either passive or active, they don't work together. I suggest you buy passive as active glasses are expensive and need charging/batteries etc.

i bought a passive Sony 3D about 6 months ago and it is superb

built in wifi that is quicker than any other wifi device i have(streams films as good as wired) and has USB ports that you can either play off or record off

the sony glasses are a LOT better than the cheaper LG ones i got for the kids, in the end i will end up buying more Sony ones as they only cost about £9 each

Passive have a polarising film in front of the LCD panel. Which works with the polarised glasses. Active displays a whole image to each eye and the brain builds it up.

With passive 3D you don't want to download SBS files you want OU files (over/under?) otherwise you only get half the resolution. They still work but you lose 50% vertical resolution. I.e. with SBS files on an active tv you get 960 x 1080 resolution but the same file on passive 3d tv's only gives 960 x 540 resolution. Where as OU files can give 1920 x 540 on both passive and active 3d televisions.

Get demonstrations of both 3D systems in store. Although I'm a plasma fan I couldn't get on with active 3D at all on either plasma or LCD. I found passive 3D far superior. Much more comfortable so I had to get a LCD set. I've lost some of the benefits of plasma now, superior SD performance and more fluid motion. However I really like 3D and use it about 5% of the time with games and movies.

If you can't really see a difference between passive and active when demonstrated buy passive. It's hugely more convenient with super cheap glasses that will always be available.

I've seen checker board and the top & bottom ones options but only come across the SBS stuff Sky and Youtube. I'll have to look in that. Thanks :)
