Over 5000 3D Fans Petition LG to add the 3D hardware back, and it sounds like LG may reconsider since it doesn't affect picture quality and the hardware isn't that expensive: https://www.change.org/p/lg-please-revive-3d-on-a-2018-oled-...

I have seen a lot of 3D movies on LG OLED sets (Gravity, Mad Max), and it's remarkable. Much better than 4K UHD. With the latest LG OLEDs, you get 1080p per eye, bright smooth motion, and the passive glasses are cheap, lightweight, and you don't have to charge them.

I was completely surprised by how great home 3d is! And I don’t really like 3d in the theatres at all.

Last year I bought a 55” 1080p LG OLED and on a lark, picked up a 3d blu-ray to see how it looked. Jeez, I was totally blown away! So much better than the movie theatre “Real 3D” while using the same passive glasses. A ridiculously beautiful 3d effect that was easy on the eyes. Just amazing. I started to stockpile whats left of the 3d blu-rays being produced. Thankfully, the 3d blu-ray editions tend to have all of the 2d versions as well, so it’s not the end of the world.

Favorite 3d blu-rays: Avatar (omg, just incredible), Inside Out (hankies required). 3d animated movies are the best.

I will go over and add my name to the petition. Home 3d is great.

I agree. Passive home 3D is great, and it's a shame that so many people have made up their minds about 3D before experiencing it on a passive 3D TV at home.

The petition page quotes LG as saying "3D is just no longer a big selling point." And somehow, curved TVs are a big selling point? I'm not sure if I'll ever understand that one. Even 4K is a pretty laughable selling point at the sizes/distances experienced by most home viewers.

Just as a counterpoint, I've seen it on a 4K LG OLED tv and I thought it was just as "meh" as theater 3d.

I also tried to get some 3d games working because I thought it might be better than movies, but it was decidedly worse. Like, really bad. Headache and nausea inducing in mere minutes bad. This is probably the reason that hardly any games support 3d tvs any more.

Curved TVs seem interesting for large TVs in 'home theatres', but in actual living rooms it seems like a disaster. Sorry, you're off the centre axis so 50% of the screen is warped for you, if not completely occluded.

I coughed up the money for a LG 4K OLED set last year, and suddenly I'm in love with 3D. For those that hate 3D, the experience on OLED is a while different world. Well-done 3D releases like Tron Legacy and Mad Max: Fury Road really come alive on this display. If you're in a store where you can demo one of these, get the salesperson to put on a decent 3D Blu-Ray release, I think you'll be impressed.

I saw Tron Legacy in 3D in theatres, and it was one of the most well-done 3D movies I've ever seen, in large part because they almost never used it. Except they did, it just wasn't obvious, and when it was it was obvious for the right reasons.

Likewise, the 3D in the Doctor Who Day of the Doctor special, which I saw in theatres, the 3D was well done because they used it in specific spots and in subtle ways.

3D should be an accent, not a centrepiece. Some movies get this right, lots get it wrong.

Indeed, doing the real-world portions of Tron Legacy in 2D and the in-the-grid portions in 3D worked beautifully. I also happened to pick up a magazine about visual effects which contained an extensive interview with one of Tron's vfx designers, and it mentioned lots of cool details I missed when first viewing the film, e.g. check out the fireworks when they introduce the light cycle battle.

I really hope they continue offering 3D TVs, especially since 4K offers the option for full 1080p passive 3D to be a possibility. I found a couple TVs that can do it already, but right now they're pretty expensive.

If they actually do fully do away with 3D sets, I'll be looking to nab an older model when they drop in price.

Where can I read about this "hardware"? My understanding was that it was simply TV's with better color clarity and then marketing fluff. I've never heard about this "hardware".

Edit: Here's a decent resource. Still doesn't talk about a hardware chip but rather about multiple LCD screens or blacking glasses that are synced with the TV. Both options sound rather expensive.

OLED is fundamentally different than LCD for 3D purposes. OLED can near-instantaneously flip between the left/right eye views, so your perception in each eye is a clear image. LCD's refresh rate is much slower by comparison, leading to each eye getting a more blurry image.

Active 3D required an emitter that synced glasses to the TV's output, and the glasses themselves.

I assume passive 3D required some hardware to support it too, and both required hardware with firmware that could support the formats and settings required

It requires a polarizing filter/film that's aligned with the screens dot matrix.

In theory that could also be added as aftermarket modification.

If the screen is fed with an interlaced 3d stream and the screen firmware/hardware allows 1:1 pixel playback it doesn't need to know if the content is 3d or not.

I was aware of passive 3D being done with aftermarket filters (mostly as a joke, printed on laminate), but proper consumer 3D had to support the same formats that Active 3D did, which usually meant side-by-side and top-bottom

Interesting. I bought a top-end 4k set a few months back, and I'm not even sure if it supports 3D, but I think it does -- it seems like it was basically 'standard' on anything high-end enough. I could look into picking up a set of glasses, but then I'd probably need a new player -- my PS3 might not support 3D, and then maybe I have to worry about HDCP because I don't have the latest 2.2 HDMI receiver. Or maybe they're just interlaced 1080p/30 frames.

Honest question, has any of those online petitions yielded results ever?

>3D Fans Petition LG to add the 3D hardware back

All 10 of them?

I find that 3D is a gimmick even at the cinema, even more so from a TV.

If you're wondering why you are getting downvoted, its because you seemed to have looked right over the "Over 5000" part of the first sentence.

5000 and 10 are close in order of magnitude to insignificant regarding consumer electronics adoption.

I'm sorry, but if you believe that 10 people and 5000 people signing a petition are close enough to be insignificantly different, you're objectively wrong.
