Just been looking at 3D systems and am unsure of Active or Passive.
Which platform (if any) requires you to be directly facing the TV to get the best picture. Whilst in my local TV centre the guy said you didn't have to be directly in line with an Active set to get the best effect whereas with passive you needed to be as best as you can in front of it and not off to one side?
Now, I may be talking hoop but its something that has stuck in my mind.

LG gives up to seven pairs of glasses and we've had six watching at once with no problems.
Active, needs to be as near as straight on as possible.
Many stores push active as they make more money selling expensive glasses.
LG Cinema 3D is IMO the best. I bought my second one recently.
Here's a good LG sales demo.

waiting for the TVs to come down a bit, although I bought a 24" LG I saw cheap fora PC monitor/ occasional 3D screen, and I was amazed how good it was.
Very true - I got 4 pairs with mine and I also found the Real3D glasses you get at the cinema work just as well, and i've got 3 pairs of those in a drawer somewhere as well. So pretty sorted if i wanted a 3D viewing party .. heh
The LG is fantastic. i rely mainly on Sky for 3D, but the other day I popped into Blockbuster who are having a closing down sale and bought the Hugo 3D blu-ray for £7.
The disc has both 2D and 3D and the clarity and definition is equal. I even tested certain scenes with fine detail (eg newspaper headlines on news stands) and they were the same.
The LG Cinema 3D sets are stunning. Shame the likes of Currys and John Lewis and even Which? push active so much.
Passive 3D has cheaper glasses, no batteries/charging and no flicker. It's simply easier to use.
Depends which is more important to you.
Just got to figure out the best picture settings now!! If anybody has any tips then please post!!
I use these, which were done by someone with the Disney WOW calibration blu-ray. I downloaded some calibration files and made a couple of adjustments.

If you want to see some stunning 3D, go to 3D World, documentaries and look for Insects Talk.

Get "Despicable Me", its a must buy 3D bluray.
Me too.
See also "Finding Nemo", "Hugo" and "Dark Country".
I have no interest in starting some crazy fan-boy war with you, but good grief, there's some rubbish in there.
If you're just wanting 3D... Passive.
Active is the better system and bullshit aside from those who do LGs dirty work and talk active down it has THE Full HD 3D experience .
Passive gets messy off angle.. Full of crosstalk, reduced resolution and IMO the 3D always looks forced and unnatural.
Passive is great for families and watching during the day but serious film watchers who care about quality should not only look at closer to reference level Plasma but also Active 3D.
This forum needs a Like button!
Actually, that's not true. Serious people use passive 3D.
Active 3D is limited to 720p due to HDMI bandwidth limitations (or it was as of 1.4, maybe there's a new revision now). You can get 1080p but only at 25Hz.
Serious gamers prefer passive because it works at the full 60Hz..
Plus, the reports I've seen say that crosstalk and viewing angles are worse with active, so I'm not sure were you got your info from.
I quite willing to be proved wrong though
Passive crosstalk is more common due to the off angle problems. Couple that with the lower LCD standard of picture and you just add more to the mix.
Also reference level 3D is plasma territory. Better motion resolution, contrast the lot. Due to the drive systems etc plasma uses active.
Where you got 720 from O have no idea. 3D Bluray is what a lot of people will get on a 3D TV and you get 1080 full HD.
Apart from projectors the next thing for critical viewers would be a active large screen plasma.
The LG passives look good at first but its forced and cut out looking. The motion blur and lower motion resolution coupled with the fact it's not full HD all add up.

Sorry, but that's utter nonsense
Active is better quality than passive, and has higher resolution - the BIG (only?) advantage of passive is the low cost of the glasses.
You pays your money and you takes your choice
Personal I wouldn't bother with either
Depends on your point of view
I meant for those that ARE interested in 3D lol
Flicker free, little or no crosstalk, wide viewing angle....
Here's another independent comparison

"No difference" she snorted.
So I walked over, popped on a pair of glasses. The screen was just as blurred as it was without thems. So I took a few steps back. Nothing. I bent my knees to lower my height, and bingo. The 3D jumped into life.
The woman tapped me on the shoulder. ”Waste of time isn't it"
"Not really" I said, "you just have to be in the right position, like this"
She snorted and walked off, muttering to her husband.
2 things can be drawn from this. Firstly, is that 3DTVs aren't going to sell with crap in-store demos like that.
Secondly STOP WITH ALL THIS CRAP ABOUT PASSIVE HAVING BETTER VIEWING ANGLES. IT SIMPLY DOESN'T.
