WXGA is listed as supporting a resolution of 1366×768 at http://www.fourmilab.ch/documents/howmanydots/ b4hand 00:09, 20 Nov 2004 (UTC)

Acer uses a WXGA monitor in Travelmate 2300 but its resolution is 1280x800, not 1280x768. NSK 00:16, 4 May 2005 (UTC)[reply]


I believe the problem you're both running into is that WXGA doesn't ultimately mean that much in terms of the exact resolution supported. These terms have gotten pretty fuzzy over the years as manufacturers have released more unusual resolutions. However, I was unable to find a reference for this. All I found was an article referencing both 1280x768 and 1360x768 via google's domain search (WXGA on vesa.org). Not helpful for this. --Steven Fisher 14:39, 17 May 2005 (UTC)[reply]

The Sony Vaio FS640/W also runs the WXGA resolution at 1280x800. As Steven Fisher pointed out, the WXGA resolution is not really pinpointed to an exact number, but rather a wider display in proportion to previous configurations.

http://www.computerhope.com/jargon/w/wxga.htm says it's 1366x768: "supports a max resolution of 1366 horizontal pixels by 768 vertical pixels." -- newagelink 20:29, 30 July 2005 (EST)

Projector USA lists both 1280x720 and 1366x768 as of 07:02, 14 September 2005 (UTC). I suspect this is a genuinely ambiguous issue in the industry. For any authoritative resolution of the issue (pun duly considered), the edit ought to reference the specific industry group standards involved. Abb3w 07:02, 14 September 2005 (UTC)[reply]

I have noticed that LCD TV screens have either resolution. I guess if you buy a 1280 x 768 model you lose some of the widescreen info. In fact I compared in john Lewis today and the smaller resolution screen misses information on the left!

You should not lose anything due to the resolution--something else in the TV/settings/system is at fault. Technically 1280x768 should be better because this requires no scaling for 720p content (assuming square pixels). --74.46.213.148 (talk) 13:14, 12 February 2008 (UTC)[reply]

Can we agree on this: WXGA is a Widescreen display, which (in my experience) means the ratio 16:9 of horizontal size to vertical size. (See Widescreen#Widescreen_TV). Now the bit which causes argument: 1366:768 = 1280:720 = 16:9. So whatever WXGA can mean, these screen resolutions use square pixels, which makes good design sense. Perhaps we should list resolutions commonly sold as WXGA, showing what the H/V ratio is for each. 17:12, 25 September 2005 (BST)

Well apparently according to ssm (linked to from computer display standard), I have a 15:9 or 5:3 screen. This sucks, I thought i had a 16:9 standard screen on this sony viao vgn-t250p, but it's 1280x768, not 1280x800 (is that right? or is it 868 or something?). No wonder it's so hard to find wallpapers for it. -- Too lazy to login right now 16:00, 29 October 2005 (UTC) What's wrong with 15:9? That just means you get a bit extra height, but 720p will fit perfectly horizontally. (BTW the 16:9 version is 1280x720, hence "720p") As far as wallpapers go, you should be able to find some, or you can use 720p ones or larger ones (either way set it to "center" not "stretch" for best quality). --74.46.213.148 (talk) 13:14, 12 February 2008 (UTC)[reply]

I have a model built with this barebone from Uniwill. It has a resolution of 1280x800px, which is (hear, hear) exactly 16:10, and is also called "WXGA". Yes, I do have perfectly square pixels :). So, we have aspect ratios of 5:3, 15:9, 16:9 and 16:10 - and probably others. --83.236.23.143 14:48, 2 November 2005 (UTC) 5:3 and 15:9 are the same --74.46.213.148 (talk) 13:14, 12 February 2008 (UTC)[reply]

Dell uses a WXGA monitor in XPS M140 - released on October 26, 2005 ([1]Dell Press Release.) It's technical specs list it as: "14.1-inch wide TFT WXGA active-matrix display with up to 1280 x 800 resolution" - This lends more credibility to the suggestion that WXGA can define a 1280x800 resolution.

Interestingly enough, the following definition [2]lends some useful insight into the discussion:

"WXGA: WXGA defines a class of XGA displays with a width resolution sufficient to create an aspect ratio of 16:9. Resolution is defined by the number of individual dots that a display uses to create an image. These dots are called pixels. A WXGA display has 1366 to 1280 horizontal pixels and 768 to 720 vertical pixels respectively that are used to compose the image delivered by the projector."

The concept here being that WXGA is not a specific resolution, but that "WXGA defines a class of XGA displays with a width resolution sufficient to create an aspect ratio of 16:9. "

It's not clear to me why 1280x800 is a class of XGA displays, but perhaps someone else can shed some light on that. It certainly explains why it's called "W"xga though. --Ghshephard 22:24, 9 November 2005 (UTC)[reply]

WQXGA is supported by 15.4" displays. See Dell Studio laptops. —Preceding unsigned comment added by 204.251.85.97 (talk) 02:34, 2 September 2008 (UTC)[reply]

HDTV[edit]

Should some mention be made that 1280x720 is 720p?

Done. In future, feel free to edit the article yourself. —Pengo 14:19, 12 December 2005 (UTC)[reply]

16:9?[edit]

The article states (emphasis mine):

WXGA is commonly used by LCD TV sets and computer monitors for widescreen presentation.

as well as:

Basically, WXGA means low resolution (by modern standards), wide screen (16:9), display.

Computer monitors, however, don't (commonly) use 16:9 at all. They sometimes use 3:2 (15:10), but mostly, they are 16:10.

Mostly 16:10 or 15:9 (5:3). I haven't seen any 15:10 (3:2) displays.--74.46.213.148 (talk) 13:18, 12 February 2008 (UTC)[reply]

LCD TV Convergence with Computer Display[edit]

With most/many LCD-TV's having resolutions of 1366x768 and PC connections, (such as VGA 15pin D-sub) to allow PC input, should there be some discussion about this ? Teeteetee 11:31, 28 March 2007 (UTC)[reply]

Possible mistake on the image Video Standards.svg[edit]

HDTV appeaer on the image as 1920X1080 , thats not true. Its just a part of HDTV, because its not the only resolution. And it would be nice to specify 1920 X 1080 progressive scan (1080P) as Full High Definition (FHD).

Quoting wikipedia from HDTV: "Three HDTV standards are currently defined by the International Telecommunication Union (ITU-R BT.709). They include 1080i (1,080 actively interlaced lines), 1080p (1,080 progressively scanned lines), and 720p (720 progressively scanned lines). All standards use a 16:9 aspect ratio"

Greetings.

VS 720p[edit]

Does anyone know why TVs so commonly use 1366x768? This seems like a ridiculously stupid design decision, as it A. requires lossy scaling of 720p content, and B. isn't exactly 16:9. Why don't they just make 720p TVs... 720p? I read something saying that common video processing chips handle the resolution better, but why not just pad the 720p data with a matte for processing and then crop it back at the display, instead of scaling it? --74.46.213.148 (talk) 13:16, 12 February 2008 (UTC)[reply]

Misuse for lower resolutions?[edit]

While Asus doesn't appear to do this on their own site at all, many retailers (including Amazon: http://www.amazon.com/1000H-10-inch-Display-Processor-Battery/dp/B001BYB5ZS?ie=UTF8&s=electronics&qid=1220922795&sr=8-1 ) are describing the "Short XGA" 1024×600 resolution of the Asus EEE 900/1000 models as WXGA. See also: http://www.gadgetreview.com/2008/06/asus-eee-pc-2g-surf-intel-7-inch-wxga-notebook.html and http://www.misco.co.uk/applications/searchtools/item-Details.asp?EdpNo=311841 .

This site http://puiz.blogspot.com/2008/07/asus-eee-pc-4g.html even calls 800×480 WXGA!
