Untitled[edit]

Most of the 4k video material I've seen (in an academic context, see www.cinegrid.nl or www.cinegrid.org) was 4096 x 2160 pixels at 24 fps. See http://staff.science.uva.nl/~grosso/Publications/AmsCineGridExchange.pdf. I was curious why this format is not mentioned (is it not standardized or uncommon?)

Can someone tell me what "K" in 4K stands for? Thanks. 78.2.100.220 (talk) 15:52, 10 December 2011 (UTC)

The "k" means "Thousand". So together it means 4 Thousand which is obviously referring to the resolution. (108.87.19.31 (talk) 09:36, 10 January 2012 (UTC))

Thought the sources this article refers to speak of a horizontal resolution of 2160 pixels. (http://www.ultrahdtv.net/the-ultimate-guide-to-4k-and-8k-ultra-hd/). So the article now contradicts it source. — Preceding unsigned comment added by 62.234.11.154 (talk) 22:56, 29 December 2013 (UTC)

List of 4K monitors and projectors[edit]

I am separating individual models into separate rows since having a single row per manufacturer creates a list that is essentially non-sortable. Also, I will slightly alter the "device type" column entries such that projectors, monitors, and TVs are the first word. I will put the editorially inspired "professional"/etc part in parens to the right...

If you have any objections, please revert. If you revert though, please cite what rule was violated so that I don't make that mistake again... — Preceding unsigned comment added by 75.145.102.186 (talk) 20:09, 23 April 2013 (UTC)

I think its time to split the list into its own article. There are a range of new 4k monitors, tvs and projectors hitting stores and if the list expands it would make the article more unbalanced. - Shiftchange (talk) 15:03, 20 January 2014 (UTC)

Incorrect image[edit]

The image showing the different resolutions is off. The size of the 6K and 4K rectangles are correct, but the rest of the rectangles are too small. The 1080p rectangle is about 1010 pixels high instead of 1080, which makes the 4k resolution look more than twice the height of 1080p. I suppose the issue is that 2K and 1080p are the same thing, but instead the 1080p rectangle (and 720 and DVD) have all been reduced in size. Quinzer (talk) 15:49, 2 December 2013 (UTC)

Correct. It is misleading 146.115.129.15 (talk) 01:33, 11 June 2014 (UTC)

No commentary?[edit]

I'm sure the details here are useful, but I came here hoping to find some sort of overview of 4K tv from a consumer's perspective. Dougweller (talk) 12:37, 23 December 2013 (UTC)

Standardized resolutions[edit]

I've removed all the non-existent or rarely supported resolutions from the table of common/standard resolutions. If you want to add other resolutions to the table, explain why here.--Father Goose (talk) 05:55, 1 January 2014 (UTC)

4096*2560[edit]

I heard that this is the actual 4K res, which still has a nice 16:10 ar. But there's no mention of it in TFA. Can anyone confirm/deny the existance of this res in relation to "4K"? Zoef1234 (talk) 18:50, 10 January 2014 (UTC)

Actual how? I see some computer monitors exist. But we won't be buying 16:10 TVs anytime soon, as this aspect ratio is not defined in current Widescreen signaling. --84.209.119.158 (talk) 21:26, 14 January 2014 (UTC)

5K[edit]

Why is WHXGA (5120x3200) mentioned instead of HXGA (4096x3072)? 4096/3840 is 4k width. 5120 is (theoretically) 5k width. This is especially confusing as Youtube specifically calls HXGA (4096x3072) 4k. — Preceding unsigned comment added by 69.17.173.158 (talk) 12:01, 2 February 2014 (UTC)

Avoid use of "next-generation network" and similar[edit]

Addressing this removal [1] as requested [2]. The vague term "next-generation network" doesn't mean anything in this context (are they just talking about bitrates? migrating cable channels onto IP, as the term actually implies? something else?), and the linked article has been tagged as outdated since 2009. The article implied that you can't do 4K without such a network, which is clearly incorrect. (I imagine this is fairly clear from the new info you added noting the actual bitrates involved, which is much better.) ToBk (talk) 13:21, 30 May 2014 (UTC)
