Too bad for a group of techies they couldn't even find 3D clips to try with the TV or blu-ray player.

They had there Captain America Civil War (3D?) and didn't try it.

They should have focused more on 3D movies and less on 3D gaming (although I suppose they are a tech- and gaming-oriented channel). The PlayStation 3D TV was also probably a poor choice for an active 3D TV. Active 3D TVs got much better as the technology matured. Although I'm glad they used arguably the best LG 3D OLED ever created to demonstrate passive 3D.

There were also a lot of better, demo-worthy 3D discs in that bin that they could have used rather than just Shrek and Tron: Legacy. The one guy constantly complaining about his headaches and nausea also didn't help matters.

I'm not sure how deep their expertise really is. I think many of us could have given a more in depth discussion about why home 3D didn't catch on.

Yes it was way overhyped and very expensive at first but what so many overlook is the timeframe in which it came out on the market. According to Leichtman Research Group only 23 percent of US households had a HD monitor by 2008. Other sources cite the figure rising to over 50 percent during the next two years (saw one report which had it at 71% ). Five years later in 2013 Leichtman reported that increased to 75 percent.

And so sales of tv sets in general began to drop, dramatically after 2011 with most consumers having already made their purchases. 3D was just a victim of the time. Some in the industry cited televisions were like a commodity, being upgraded like a computer every two or three years. They were wrong.

So it was introduced to quickly to the consumer public who had just invested in high-definition sets and we're not going to sacrifice those and invest in another monitor. 3D was introduced too soon. And even with that they could have still kept it on as a feature and simply waited for consumers to buy sets again.

When Linus says that the LCD is not fast enough to stop ghosting, is he referring to the LCD in the glasses, or to the LCD of the PlayStation 3D TV?

Frankly, 120-144 Hz glasses are too slow for active 3D (this goes for theatrical RealD as well). Linus is right that the 3D makers price gouged back in the day, as today's DLP glasses are more convenient and $15 a piece. DLP projection removes many of the downsides of active 3D that they mentioned, and turn them into assets...perhaps active 3D should have been for projectors or dark room viewing only?

I notice that they also notice how objects moving laterally appear to stutter, would have been nice if they'd pointed out that Cameron claims he can correct this, but that might have been out of their ken.

The camera not focusing on the objects that your eye is drawn to is, as he mentioned, also a problem. Shang Chi has that in spades, as do more than a few of the post conversions I've been looking at. Apparently that is something that cannot be fixed in post.

What's really weird is how they were impressed by the 3D of Titanic, when the reviews of its time praised it for being a film that made you forget you were watching 3D.

I do wish that 3D glasses that could optionally only show one eye's view were available. Except for the PlayStation 3D TV ones, they're rare.

Lastly, ReShade is a free program that allows most any PC game to be played in 3D. I've been playing the old game RAGE that way, and it looks stunning. Linus mentioned Nvidia 3D Vision (RIP) but not alternative solutions.

All in all I'm glad they made the video, and maybe it'll lead to some TV makers slapping that polarization layer back onto some OLEDs, and/or projector manufacturers finally enabling 4K 3D.

Well, i just went to youtube to read the comments.

Some are great praises for the 3D, but most are just asinine people that know nothing about 3D and must only done 3D by using a dvd player and put it to convert to 3D.

Man, when dumb people try to use a wooden club things got smashed and then because they can't handle tools, because they're dumb, they say it's good because it's dead and isn't anymore in the scene. Just because people can talk and use computers doesn't mean they can handle sophisticated hardware... we all remember Jar Jar Binks... not even that character would be able to use a 3D tv even if it were explained in a way toddlers could understand.

Just because some people can't handle it or have issues with 3D hardware... just don't complain... there are other items you can buy or do... 3D movies can be seen with 3D to 2D glasses so just let the 3D hardware coexist so that people can buy what they need or want.

Jar Jar Binks tweaked Anakin's podracer, seemingly what enabled Anakin to finally win, and he was seen tinkering with the naboo ship's inner workings (to which R2D2 protested), so I think he's more tech savvy than those commenting cavemen.


3D seems to be something that folks let one bad experience ruin, or they never try it and just want to rag on 3D because it's "cool" to do.

If 3D comes around again in hardware, I'd like to see at least 240 hz glasses. Last time around we graduated from 96 to 144 Hz, but that's still too slow for 24 FPS content. It does seem to work much better with 60 and 72 Hz content.

Even a stopped clock is right twice a day. That doesn't mean that he's smart, it just means that he's clumsy and sometimes one can be lucky or not that he's around.

Preferably, battery glasses should be dropped and all 3D equipments be passive 3D, that way only the TV/projector should be the sole equipment to active display the 3D picture. Less garbage and less expenses is the best solution to those who want to watch 3D content.

For projectors to use polarized glasses, you still need to have a special, expensive silver screen installed. You also need a second projector and a polarization filter. The difficulty level goes up significantly. You could also do 2 projectors with Dooby-style color-filter glasses but that is also expensive. There’s no reason to do away with active glasses in projectors. It’s by far the lowest bar to entry for 3D on any device made after 2017. I definitely agree that if we could get new 3D TV’s, it would be great to standardize around polarized glasses (or autostereoscopic lightfield displays.)

There's no need for a second projector as there are projectors that are able to do that with single equipment.

And about those prices... if they are expensive that is because the demand is low and they tend to have high prices. If people buy passive TVs or projectors then the prices go low because the demand makes technology cheaper.

If that happens I’ll be absolutely thrilled.

I'm not sure that the silver screens are that much more expensive (last I looked it was a 50% price premium or so), and I hear that gray screens can help projectors have better contrast. Snagging 2 projectors and an alignment rig also doesn't seem that costly.
Finding a place to mount them though...

Active 3D on projectors is pretty nice, but I'd like to see modern refresh rates for the glasses. Although, as a side benefit, active glasses put the kibosh onto using a laptop while watching a movie, and they reduce the amount of phone usage during a film as well.

Ironically, I’m writing this post on my phone with active 3D glasses on while playing Doctor Strange on the TV but yes, in general 3D content/glasses definitely helps cut down on distraction/phone use. I’m rewatching Strange with the commentary track after doing a separate watch a couple weeks ago.

And I think maybe you’re joking about 2 projectors and a rig not being that pricey? Obviously everyone will have a different income level so “expensive” is relative, but I would guess that for most people, the projector is the single most expensive piece of equipment in their home theater. Doubling that price, plus the polarization rig, just to use passive vs active lenses is a bit extreme for a lot of people. If you’ve got the disposable income to do it, by all means, more power to you and I am jealous!

Actually, the Z9D-2016-4K-active 3D-HDR- model from SONY was really the last and best 3D TV out there...hands down...period...very lucky and blessed to have it...anything else below that within the T.V. REALM only...not including projectors is considered just OK and/or tolerable...also Linus and his doy side kicked would have enjoyed the 3D better with the lights off...so if anyone here is still wondering what is the very BEST way to watch a 3D movie that would be ACTIVE and most definitely NOT passive, anyone stating anything else is fooling themselves and others...The truth can hurt sometimes but alternate facts can kill.

Yes, what everyone want is to have some glasses that can brake and stop working or lose power and then hurt their 3D experience... not mentioning of watching the movies with natural light and have every other object in the view field flickering. :/

Passive not only is cheap it also doesn't have the downsides of active glasses, you may be proud of your TV and glasses set, but most people aren't prone to have complicated gizmos and to have hassle with them.

[lukas741]

You know as well as I do that there are 2 kinds of active glasses available for T.V., for ex: one that you can charge via a USB port and the other that requires a small battery, you can calculate the times of usage to charge either one, are they a bit more expensive, YES, do you need to be more cautious than the other passive-polarize cheap ones, YES, can you actually notice any other object in the view field flickering?...well I never had that issue. Proudness, happiness, satisfaction, luck...I just hope the T.V. last another 5 years.

But what i and you know isn't what most people know and that is the main reason why people passed on 3D. Tha hassle for them isn't a good thing to keep with 3D. So, for that, passive 3D is great, there are clip-on 3D glasses, reald 3D glasses, other brands 3D glasses that can isolate mor the light from the sides and allow more immersion and the costs for that are very very low. It would only take stores a little space for them to have these glasses exposed for clients to try them and would be a game changer to the format, unlike with active 3D glasses. People don't need to be educated about 3D, they need standardization on the tech.

My LG passive 3D tv is over 11 years and also works great

[lukas741]

I think you are off on why people passed on 3D...it was because of cheap passive 3D TV with bad resolution (720 P) and very low brightness levels along with those cheap flimsy polarized glasses...that is part of what really killed 3D... the truth is that active t.v. is more expensive along with glasses due to it being more superior and every way.

My 11 years TV says otherwise.

It's one of the first passive 3D TVs to be made from LG.

And it does show brightness enough that i have it just on 10% of power to watch any 3D movie i want to not have reflections on the glasses.

As i could watch on that video, Playstation 3D Display had also 720p on active 3D. Maybe that's why people stoped to like 3D. Playstation as a great brand selling bad 3D displays hurts whoever who bought it.

Of course there where also passive 3D TVs that were 720p(i don't know how that was possible) that when showing a 3D movie must have been with poor quality.

Still, comparing passive with active in an environment of family and guests, passive is much better not just because it is cheaper but because it has much less problems with lights and objects in field of vision because of the alternate shutters.

As Linus said... when 3D was in its last spasms LG brought to the market possibly the best line of 3D TVs to have ever existed and that could, if LG maintained annual releases of 4K 3D TVs, have kept or even improved 3D interresting up to these days.

When i go to watch a movie all i have to do is put my glasses... no need to sync or recharge.

[lukas741]

I understand...If you are happy and satisfied...nothing else really matters. Thank you for that back and forth conversation event...I guess I needed to vent about something even though I was having concerns about other matters in my life... a very sick mom...take good care.
