Thread starter loz Start date Sep 4, The thing is, the TV uses passive 3D tech rather than the usual for Sony active system.

But because the TV has a 4K resolution, it can deliver all the traditional passive advantages greater brightness, richer colours, no flicker, no crosstalk and a less tiring experience without displaying the traditional disadvantages of visible line structure, jagged edges and a reduced resolution.

There's no overstating how much this improves the 3D experience. In fact, it's so good it suddenly got us interested in 3D again - and believe us when we say that this is no small achievement.

Jason Shouler Novice Member. So does this mean LG have now lost their FPR manufacturing monopoly or have they in fact increased their lead even further by continuing to supply Toshiba - with Sony as a new customer in their ongoing passive bandwagon? In fact, it's so good it suddenly got us interested in 3D again. Will21st Well-known Member. Jason Shouler said:. Did anyone ever lose interest.

No cherry-picked units sent by brands. In3D TVs are all but gone. While it was often touted as a major paradigm shift in televisions a few years ago, it has been abandoned completely now.

A 3D TV uses either active or passive 3D.

tv 4k 3d active

Most people prefer passive 3D over active 3D, even though the resolution is cut by half, because the glasses are cheaper and there is less crosstalk.

All 3D images, including the ones we see with our eyes, work on one principle: each of our eyes sees a different picture. By perceiving a slightly different picture from each perspective, the brain automatically constructs the third dimension. The glasses are synchronized to the TV and shutters darken the individual lenses in tandem with the image on the screen. Passive 3D glasses have different polarization on each lens that fits with their respective lines right polarized for even lines, left for odd.

When we look at an object in real life, we see it in three dimensions because each eye sees it from a different perspective. The three inches between our eyes are enough to create two different images, and the difference between those images allows us to see in 3 dimensions. This is the basis for the two systems of 3D TVs, and they apply the same logic using two distinctive techniques.

It will make a section of the picture blurry - usually the edges of an object. The best way to experience what crosstalk looks like is to remove 3D glasses in a theater.

4K Passive 3D TVs

This is, of course, the extreme case, where the complete picture has crosstalk with normal usage, only small parts of a screen will show that defect. There are two reasons why you may experience crosstalk. First, some televisions don't do a good job of displaying the correct picture to each eye.

For example, on an active 3D TV, if the glasses are not perfectly in sync with the television, one eye can start to see part of the picture meant for the other eye.

As the shutter hides the left eye, some TVs might take long enough to display the next image that a faint trail of the previous one remains and leaves an undesirable doubling effect. Polarization used at the time would cause a very dramatic effect if the viewer were to tilt their head.

Thanks to modern polarization techniques, newer passive 3D TVs are free of this issue. Second, the actual media could contain crosstalk issues embedded. Even if each eye perceives the correct picture, the movie itself could be the problem. This is mostly present in low budget movies or movies that were originally filmed in 2D, but remastered in 3D in post-production.

The two different technologies make different uses of the resolution of the TV. Active 3D, since it alternates between two complete pictures for each eye, does not alter the resolution of the content.

Passive 3D, on the other hand, splits the vertical resolution between two frames, so it is therefore halved. This sounds like a pretty dramatic difference, but in reality, it is not completely halved. Some parts of the image are shared between the two eyes, and your brain does a great job at blending the information it gets.

This isn't perfect, but if you sit slightly further than we recommend see TV size to distance ratioit is close to imperceptible. Unless you plan on getting a p TV, then the difference is even smaller with 4k TVs.The backlash from consumers reached a point where a couple of actual petitions were started on the website Change. Whether it was due to the online petitions or broader consumer pressure, LG responded to hastily address the issue and a firmware update was beamed out to most LG HDR TVs in an effort to fix the problem.

This latest complaint by LG fans has also spawned an online petition, which was launched shortly after LG made the announcement of 3D support exclusion at CES in early January and the consumers behind it want LG to fix the problem with its next unveiling of TVs in The number is certainly not something to ignore in a market as competitive as 4K TV manufacturing.

The company claimed that it decided to forego 3D support in favor of much more widely popular and thus arguably more important technologies like HDR.

We can probably assume that this same attitude will translate into the models. You shut your fucking mouth. This is sad news. To me and my family, OLED passive 3d is simply better and more immersive. They should really keep both, and ultimately should upgrade 3d to 4k 3d HDR. I know this is subjective, but I believe this move goes backwards as 3d is simply better than 2d when properly implemented… And now finally with bright fast contrasty OLED tvs and laser projectors iMax laser and AMC Dolby cinema laser3d is better than ever and is overcoming the 3d weaknesses that the dark and blurry original tvs and projectors had.

Not only my big screen LG p smart 3d tv that one day I would of like to up grade one day. They may not even have stopped production of all of their sets yet. It will actually be easier LG to keep making 3D sets while they still have the production lines setup and stock of polarized screens than if they stop making 3D for one and try to add them back in the following year.

LG and Sony and Samsung have all publicly stated that 3D technology is no longer something that interests them for their newer TVs. BTW, the reason no one complained when Samsung and a few others removed 3D from their tv lineups is simple- the active shutter glasses they used were pure crap.

They made a large number of people sick, the glasses are heavy, they run out of batteries at the most inconvenient times and they cost a ton of money. Good riddance.


Although I am still using an ancient LG 55LW, the passive 3D quality directly from Blu-ray 3D discs and even converting standard Blu-ray discs as well as high resolution photos to 3D is so shockingly astounding, that, I hail it as the finest invention in all of television history. I do not understand how so many people can be outrageously clueless enough to not realize this. Why is there always some Cyclops to loudly proclaim the great lie, that 3D television is just a gimmick?

Certainly there is some poor quality 3D content, to go with the 10, times more garbage available as 2D content.The support shared between readers in the comments section is one of the things we love most about the Engadget community.

I really enjoy watching 3D Blu-rays at home and have a good collection. Now that 3D capability seems to have been dropped from most, if not all, new TVs, what do I do?

My current TV is a Samsung inch and only p. I really want to get a new plus-inch 4K model with 3D capability not a projector. What are my best options?

Devindra Hardawar Senior Editor. Consider yourself a rare consumer. While 3D was something the movie industry and TV makers pushed hard a few years ago, it wasn't widely adopted by many. Like most failed formats, the problem lay in its complexity.

Once you were set there, you had to figure out what sort of glasses you needed to use and keep them charged, if they were "active" frames. So, it's not a huge surprise to see support for the format dwindling today, especially as we have more impressive technological leaps like 4K and HDR. So where does that leave you? While you don't have many 3D options in low-end and mid-range 4K TVs, there's still support in some higher-end sets. You might also see some older 4K sets from around with 3D, but I'd steer clear of those since they don't offer HDR, which is the real visual upgrade in modern TVs.

And I know you're not interested in projectors, but honestly they're worth considering since plenty of p models have 3D, and it's a format that really benefits from being viewed on a giant screen.The right 3D television for you is just a click away.

Since their debut, 3D TVs have definitely dropped in price, but most of us can agree that they are still an extravagance. I hate 3D movies. I've seen two in theaters, and they disorient me and give me headaches…so, this was truly a birthday present for her.

Therefore, I had to decide between active and passive 3D TVs.

Samsung SSG-5150 Active 3D Glasses Review, Unboxing and Demonstration

Passive glasses use polarized glasses, and the TV has a filter that polarizes each line of the pixels. There used to be many issues when trying to watch movies and TV shows in 3D before the introduction of 4K TVs as Morrison notes, and I will try to summarize a few of these issues. In terms of using passive glasses on a non-4K TV, the human eye can only see 1,x pixels because the polarize lenses hide half the lines.

This means that viewers paid to watch a p TV, but only half of that resolution is seen when using the 3D feature! To add to that gripe, users can see lines on the TV. With active glasses, human eyes do view the full p resolution, but they can show crosstalk, which is when a second ghostly image appears to outline the original object. When speaking with a Best Buy salesman, he said that some users also see the active glasses flicker because the lenses alternate between opening and closing, which can be bothersome.

Additionally, active glasses can sometimes dim the screen because they block some of the light. While at Best Buy, I tried on the active glasses, and they are definitely more cumbersome because of the battery. Passive 3D definitely seems like the better option of a bad situation, right? We watched Harry Potter and the Deathly Hallows: Part 1and I have to say that the part when the snake popped out was awesome.

The other cool feature that we tried is turning regular television programs into simulated 3D. Instead of objects popping out, the feature creates more depth to the image and makes objects visually stand out more.
