There are just two 3DTVs on the market right now—a plasma from Panasonic and an LCD from Samsung. Luckily, that means it's really easy to spot which is the best.
We tested two HDTVs that use the new Full HD 3D standard: the $2900 Samsung UN55C7000 (a 55-inch LCD, on the left in the photo) and the $2500 Panasonic TC-P50VT20, a 50-inch plasma on the right. We tested them with the requisite 3D glasses and a Panasonic BD-C6900 3D Blu-ray player playing both a 3D movie (Monsters Vs Aliens) and a disc of sample footage that came with the Blu-ray player.
Both displays require you to look like a dork by wearing a pair of 3D glasses. That's what produces the 3D effect: the glasses contain LCD shutters that turn on and off to show each eye a separate image 60 times a second. Without the glasses, you see a confusing mess of two images slightly offset. With them, you see the 3D effect, but this means that you need a pair for every person watching, and they cost $150 each.

In use, we found that both HDTVs produced a decent 3D effect, with a good sense of depth to the images. This experience was far from perfect, though; the 3D effect often broke down when the camera panned around or moved quickly. That's because the 3D effect relies on the brain detecting the differences between the two images, and that doesn't work when it can't figure out the difference between one blurry mess and another.
The Samsung displayed an annoying issue with a ghost image that showed up around the edges of objects, caused by some of the left frame getting into the right eye and vice versa (the technical term is crosstalk). Indeed, the Panasonic actually had the same issue, but to a much lesser degree. It isn't yet clear if this phenomenon is caused by a slight mismatch between the timing of the frames on the screen and the shutters on the glasses, or by a lag in the response time of the LCD screen that the Samsung uses. Plasma displays like the Panasonic TC-P50VT20 can react much faster than an LCD, so the screen can show the two images with much less interference between the two. Whatever the cause, it is very irritating and distracting.

Size has a lot to do with this. Even at 55 inches, the physics of 3D are against home theater enthusiasts. So you'll still want to glue your face to the screen to maximize the 3D effect.
Then there's the issue of price...
As well as the cost of the TV itself, don't forget to include the cost of the glasses ($150 a pop: you get one set with the Panasonic and none with the Samsung) and $400 for the 3D Blu ray player, because your existing one won't play 3D Blu ray discs (though the PS3 will receive an update this summer). Total that all up for a family of 4 and you are laying out a hefty $3700 for the Samsung or about $3350 for the Panasonic.
And don't forget that you'll need to find something to watch—the only option right now is the execrable animated movie Monsters vs. Aliens, which gets old pretty quickly. At the moment, that's the only 3D Blu-ray available, so you'd be better off getting your 3D kicks from going to see Avatar again and saving your cash until the price of the glasses for these 3D HDTVs falls.
But if you are dead set on being the first one on the block to have a 3D HDTV, the Panasonic TC-P50VT20 is the better pick right now. The Panasonic produces the stronger and more convincing 3D feel, and comes with one pair of glasses. The Samsung is a bigger, brighter and perhaps better overall HDTV, but the 3D is still a little glitchy and you don't get any glasses with it.
Basically, you may one day choose to watch 3D on the Panasonic. But the Samsung teeters on "just because you can doesn't mean you should" territory.

Maybe they should use the technology the Nintendo 3D DS is placing in their handheld consoles. Doesn't require glasses at all, but I think the 3d effect will only work for one person at a time...
Also, this is just another reason why we should start looking for true hologram technology so we can have advanced monitors and such like in the movie, "Avatar".
This seems like the most expensive possible way to make a 3D TV. Why would Panasonic and Samsung invest in a system that requires $150 glasses with LCDs in the lenses? Are parents really going to entrust their kids with $150 BREAKABLE gadgets so they can watch "Monsters vs Aliens" in 3D? One good sibling wrestling match could cost you $300 or more.
Is it too difficult to build a TV that uses polarized light, which would allow people to use the cheap $5 glasses instead?
Maybe it has to do with the Flagship version will be released by Sony Corp. and Lg Mgf.In which They will have a better Shutter Glass(along with superior Technology:Such as Tru-motion among other things).But they all have cons,the next tv to hit,that will change everything,will be OLED tv.....By Sony.But the price is steep,and it is the first generaion to hit the US.The Resolutin is 1 million plus....Why by this crap(3D Tv)?The scrubs are trying to make a quick buck.Samsung does that to all of their products....for instance,There refrigarator is no more than a replica of a "Maytag" brand.Samsung,just spends alot of money(up front)on comercials.They get the jump start!Everything that they touch is crap.The company that sells them,want you to get a warranty(the most expensive of all of the other warranty companys)and they will break down very quickly...Last but not least. 3Dtv,will be gone as quick as the laser Disc player.
Forget 3D tv's, just wait for Holographic ones. =D

maaan F**K 3D!! if were gonnna need stupid glasses just make augumented reality.
At least for video games u culd put glasses on look at a coffie table with little tanks on them. You would be the commander of a virtual battle field.
thats only one senerio. if we ever want to expand into better views like 3d we will have to get rid of the tv. that only limits our potential due to its size
Ok,so most 3D TVs use alternating image 3D technology. This requires the purchase of expensive and ugly LCD shutter glasses. The type of 3D used in the avatar theaters is line interlace, where essentially the pixels of two images are super imposed and woven together to make them 3D when shown through special glasses (glasses which cost at most 10 dollars). The only example (that I've seen) of a screen using this kind of 3D technology out of theaters is the acer Tridef 3D computer.
oh and also the resolution of line interlace is HD, as opposed to polarized light, which sucks.
Here is an interesting article to review!
