Quincunx
Article says that quincunx is a method of 3D tv coding distribution with a link. Following the link yields no further information about the claim and no further information is given in the article. I will delete shortly if information isn't forthcoming. --Spuzzdawg (talk) 10:00, 16 February 2010 (UTC)

Delete? Speedy rewrite/cleanup?
The top reads like a bloody commercial advertisement—and the rest looks so un-Wikipedia-y at first glance that I haven't even read any of it. Brrrrr. — President Lethe (talk) 01:31, 11 November 2008 (UTC)

3D vs. 3-D
We have (at least) four related pages on 3D/3-D technology:
 * 3D television
 * 3D display
 * 3-D film
 * List of 3-D films

Clearly there is an inconsistency between "3D" & "3-D". I checked both Merriam Webster (USA) and Collins (UK) and both show "3-D" and not "3D" ... also, I ran a Google search of each term and found 367 million hits for "3D" and 1.2 billion hits for "3-D".

By both measures, I believe we should be using "3-D" throughout in the above pages (and maybe more).

Enquire (talk) 04:40, 26 September 2009 (UTC)

-- I agree that as written, 3D television and 3D display could very easily be merged. As for the discussion about 3D vs. 3-D, it's sticky. AP style guidelines hyphenate it. However, other corporate brand guidelines I've worked with remove the hyphen. My personal preference is 3D without the hyphen. But of course, I also prefer e-mail without the hyphen, and Web site as one word (no capital W), so what do I know?!? —Preceding unsigned comment added by 66.193.255.108 (talk) 14:49, 6 January 2010 (UTC)

Modern usage seems to be dropping the hyphen. "3D-Ready" (used on most 3DTVs and 3D projectors) would be very awkward with the extra hyphen. "Blu-ray 3D" doesn't use it. etc. —Preceding unsigned comment added by Awoods3d (talk • contribs) 09:31, 12 February 2010 (UTC)

now there is 3D cinema model from LG electronices. please research and write some article. — Preceding unsigned comment added by 178.152.94.186 (talk) 20:48, 19 July 2011 (UTC)

TCL Price Reference
Hey, here's an idea. If we put a price in dollars ($), why not specify WHICH dollars ($) we are referring to? http://en.wikipedia.org/wiki/Dollar#Countries_which_use_the_dollar Many countries use this unit, and the all have very different values. At this rate, you may as well not specify a unit of currency at all.

SKY 3D Korea?
Shouldn't it read 'CJ HelloVision' in Korea?

This sentence is horrible
The below sentence should be made readable. I am not even sure what it's trying to say, and I understand a bit of the new 3D technology.

"To present faster frame rate in high definition to avoid judder, enhancing 3-D film, televisions and broadcasting, other unresolved standards are the type of 3D glasses (passive or active), including bandwidth considerations, subtitles, recording format and a Blu-ray standard." —Preceding unsigned comment added by 15.203.233.76 (talk) 15:56, 16 April 2010 (UTC)

Incorrect verb tenses
There are some sentences that have future verbal tense especially under "3D Channels" section but the times they're referring to have actually passed. I believe these entries haven't been edited and revised for some time. I am not sure whether they have happened on the given dates or not so I left them unchanged. —Preceding unsigned comment added by Haghshenas m a (talk • contribs) 11:56, 3 May 2010 (UTC)

Football Clarification
In the section 3D Channels, are we talking about American football or football/soccer? —Preceding unsigned comment added by Nicky Nouse (talk • contribs) 07:04, 6 May 2010 (UTC)

It is usually pretty obvious from the context - most references I found to football mention the teams involved immediately before or after mentioning football. For clarity though, I think it's logical to refer to Soccer as Football and refer to all the other types of football as American Football, Rugby Union, Rugby League & Australian Football as I believe the majority of the english and non-english speaking world call soccer Football. --Spuzzdawg (talk) 06:50, 13 August 2010 (UTC)

Criticisms?
So, no criticisms section? 24.72.187.165 (talk) 04:10, 19 June 2010 (UTC)

Date of 3D starts on videogames
2010 is the starting year of 3D in consoles, not in videogames. I play 3D games in my computer since 2006 with a eDimensional glasses, and since 2008 with a Zalman Trimon, so this date is absolutely wrong. —Preceding unsigned comment added by 85.59.111.160 (talk) 22:29, 22 June 2010 (UTC)


 * Certain Nintendo games like Rad Racer had an an anaglyph 3D mode, so 3D games go back to the 80's. MMetro (talk) 18:21, 2 August 2011 (UTC)

TV sets
The difference between 3D-ready and 3D TV sets is that 3D-ready uses a set-top-box to connect the glasses (and are generally, 200 Hz or higher TV sets); and in 3D TV sets the glasses are diretly connected to the TV set. --Hamiltha (talk) 21:06, 19 July 2010 (UTC)


 * What about TVs that don't require glasses to view in 3D?


 * I think this section needs a bit of re-jigging although I don't know enough about the subject to add much at present.


 * My understanding of "3D-ready" - similar to "HD-ready" - is that the screen is capable of displaying the 3D image regardless of the technology required, but requires an external 3D tuner to capture and process the signal from appropriate media (tererrestrial, satellite, DVD, etc. Should this be explained in more detail? Also, I've just added an announcement from Toshiba about their new range, but it should probably go in the Full 3D section.  Regards. Lynbarn (talk) 14:16, 25 August 2010 (UTC)


 * I agree with the re-jiggering, although I don't know enough about it to do it (why I'm here..) I was puzzled by the heading "Full 3D" wondering, what's the difference. — Preceding unsigned comment added by 98.223.232.121 (talk) 23:58, 26 January 2012 (UTC)

Technologies sterescopy section poorly written
The part of the article describing the algebra behind sterscopic technology is poorly written and lacking citation. Whoever wrote it is clearly a douche bag who is interested in displaying his knowledge for the world to see. Fragments like "we can... using simple algebra...". Have no place in an encyclopedia, scholarly article, newspaper, peer reviewed journal, or any informative piece of writing. These articles are not discussions with your friends but encyclopedia articles. I suggest a re-write to improve the quality of the article and the reputation of wikipedia in general. — Preceding unsigned comment added by 75.109.134.47 (talk) 23:13, 29 July 2011 (UTC)

3D Channels - Brazil
In Brazil Rede TV! became the first Terrestrial television to transmit 3D signal freely for all 3D enabled audience on 21 May. But despite their technology, its programming is still in poor[neutrality is disputed] quality.

This poor is refering to the quality of the content of the programs, NOT the transmission signal, while I agree with the statement, this should not be here as Wikipedia should not be a place for personal opinions. 201.86.41.210 (talk) 01:56, 31 August 2011 (UTC)

"The Real World"
The article stated:

"The first-ever 3D broadcast in the UK was an episode of the weekly science magazine The Real World, made by Television South and screened only in the south-east region of the UK in February 1982." It wasn't limited to the TVS region - I *think* it was national except for one or two areas - it was certainly shown in the Granada region.

Was the series initially shown only in TVS, then repeated nationally ?

Judder?
What on earth is Judder? The link goes to nowhere. I am saddened by this. :<

Redirect to 3D display?
As the substancial difference between 2D television and 3D television is the Display mechanism a merge or redirection to the 3D display article may be more effective

Last sentence before History section
What does it mean? Someone please revise or remove.

Inaccurate regarding 120hz
I have a problem with this sentence: "These TV sets usually support HDMI 1.4 and a minimum (input and output) refresh rate of 120 Hz; glasses may be sold separately."

None of these TVs support 120hz input because at 1080p that would require an HDMI-B connector, which no existing TVs use. True 120hz input is possible on a handful of computer monitors and only then with a Dual Link DVI cable.

Statistics
There is not enough statistics amount the # of households in the country that own a 3D television right now or predictions about how this technology will be used in the future

Achitn (talk) 05:01, 20 March 2012 (UTC)

3D versus regular television?
What television is incapable of displaying properly encoded (e.g. EIA/CEA-861 as used in HDMI and DVI) anaglyph images? Are anaglyph images not encodable under standard encoding techniques in use on standard/regualr/non-3D television sets? If a television can display anaglyph images, doesn't that mean it is a "television set that employs techniques of 3D presentation"? In addition, what does it mean for a television to employ techniques of presentation? Is the television doing anything other than displaying an image, which may or may not employ techniques of 3D presentation? I have also made related questions/arguments at Talk:3D_display. Int21h (talk) 00:44, 12 January 2011 (UTC)
 * Yes, if a television displays anaglyph images it is 3D television. --Fluffystar (talk) 14:52, 7 June 2012 (UTC)

Movies
How exactly will movies be effected by 3D technology? Will the way movies are filmed be different and what kind of impact will this have?

Achitn (talk) 05:03, 20 March 2012 (UTC)


 * This is a topic for the 3D film or the Stereoscopy article. --Fluffystar (talk) 12:33, 8 June 2012 (UTC)

3D-ready TV sets vs Full 3D TV sets
The article says:

"3D-ready TV sets are those that can operate in 3D mode (in addition to regular 2D mode) using one of several display technologies to recreate a stereoscopic image."

Does it mean that Full TV sets are those that can not operate in 3D mode (in addition to regular 2D mode) using one of several display technologies to recreate a stereoscopic image?

As for me, this in a nonsense.136.169.206.154 (talk) 08:21, 17 July 2012 (UTC)

"Health Effects"
There isn't much information on the health effects - what else could be added to this portion of the entry?

Achitn (talk) 05:01, 20 March 2012 (UTC)


 * Added eyestrain and motion sickness. --Fluffystar (talk) 12:59, 8 June 2012 (UTC)


 * That's true, the article does not cover the health effects of 3D TV on specific groups like children, pregnant women or people under the influence of alcohol. But I think the information about the effects on kids should be prioritized, since it seems to affect them the most. It is stated 3D can affect the development of the eye. Please check those references: http://news.bbc.co.uk/1/hi/programmes/click_online/9378577.stm and http://www.abc.net.au/unleashed/32814.html Many thanks, Zalunardo8 (talk) 12:11, 1 February 2013 (UTC)
 * It would be preferable to have a scholarly reference by some refereed publication, instead of a sound-bite prepared by soem deadline-addled TV journalist, looking for tonight's scary science story ("Something in your house will kill you! More after these ads..."). --Wtshymanski (talk) 14:17, 1 February 2013 (UTC)
 * Maybe this reference, Wtshymanski? It is ABC but they are referencing a study done by UC Berkley http://abclocal.go.com/kgo/story?section=news/drive_to_discover&id=7637965 Cheers, Zalunardo8 (talk) 15:37, 1 February 2013 (UTC)

Confusing/missing info
The sentence at the end of the top-level Technologies heading didn't make much sense to me: One might be able to obtain information directly onto their television due to new technologies like the Visible Light Communication that allows for this to happen because the LED lights transmit information by flickering at high frequencies. What “information” is being referred to? Hasn't the whole point of TVs from the very beginning been to display “information”? After reading about what visible light communication is, I'm guessing that the idea is that one could interactively obtain data, in a similar way as on the Web, but I'm still left wondering how visible light transmission fits into this. I feel the passage could have been more clear.

Also, I was expecting some discussion on how 3D television success/adoption/reception has been. The article barely seems to hint about this at all.
