Display resolution
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g. red indicates a 4:3 ratio). The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight".

Display size Comparison of screen sizes by width, height, diagonal, area, and aspect ratio. On 2-D displays, such as computer monitors and TVs, the display size (or viewable image size or VIS) is the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners. Optimal screen size and viewing distance[edit] The TV image is composed of many lines of pixels. Display sizes of common TVs and computer monitors[edit] Knowing the actual height and width of a screen is useful when deciding which one to purchase. History[edit] The practice of measuring display devices by the diagonal is a remnant from the time when cathode ray tubes were used, which basically created circular projections, and any rectangular area derived thereof had a diagonal equal to the circle diameter. When the common aspect ratio went from 4:3 to 16:9, the new widescreens were labeled with a W. See also[edit]

Aspect ratio (image) The aspect ratio of an image describes the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units. For example, consider a group of images, all with an aspect ratio of 16:9. One image is 16 inches wide and 9 inches high. The most common aspect ratios used today in the presentation of films in movie theaters are 1.85:1 and 2.39:1.[1] Two common videographic aspect ratios are 4:3 (1.33:1),[a] the universal video format of the 20th century, and 16:9 (1.77:1), universal for high-definition television and European digital television. In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. Rearranging (solving for PAR) yields:

Responsive Web Design - partie 3 : Taille d'écran, résolution et media-queries Nous allons voir ici comment mettre en oeuvre le Responsive Web Design en fonction de la taille et de la résolution l'écran des principaux appareils du marché. Le module CSS3 Media Queries permet d'adapter le rendu des pages en se basant sur des conditions comme la résolution d'écran. Les Media Queries constituent donc la brique essentielle à la mise en oeuvre du Responsive Web Design (RWD). Vocabulaire La définition : Le nombre de pixels en largeur x le nombre de pixels en hauteur. Définition des écrans courants On trouvera ici : une liste d'appareils avec leur définition et leur résolution. Un graphique qui résume pas mal de choses ... Compatibilité des Media Queries Les Media Queries sont une recommandation du W3C depuis Juin 2012. Le principe général L'idée pricipale consiste à segmenter le CSS d'un site en fonction de la largeur des écrans des cibles sélectionnées.

Standard Resolutions - equasys GmbH Apart from some exotic display formats, most of the displays within consumer electronic devices, handheld devices or computer monitors match to a (more or less) standard display resolution.The following tables contain a list of commonly used standard resolutions, used for computer graphics equipment, TV and video applications or mobile devices. Resolutions of Computer Graphics Equipment The following table contains a list of all popular computer display formats. * number of pixels: 1 k = 1024 and 1 M = 1024 k = 1048576 Resolutions of TV and Video Applications The following table contains a list of all relevant resolutions defined by digital video standards and used within TV or video equipment. * number of pixels: 1 k = 1024 and 1 M = 1024 k = 1048576** using non-square pixels (see aspect ratio for additional information). Resolutions of Mobile Devices * number of pixels: 1 k = 1024 Terms of Use Please use the Contact sheet to submit any comments, proposals or feedback.

Computer display standard Computer display standards are a combination of aspect ratio, display size, display resolution, color depth, and refresh rate. They are associated with specific expansion cards, video connectors and monitors. History[edit] Various computer display standards or display modes have been used in the history of the personal computer. Beyond display modes, the VESA industry organization has defined several standards related to power management and device identification, while ergonomics standards are set by the TCO. Standards[edit] A number of common resolutions have been used with computers descended from the original IBM PC. Display resolution prefixes[edit] Although the common standard prefixes super and ultra do not indicate specific modifiers to base standard resolutions, several others do: Quarter (Q or q) A quarter of the base resolution. Wide (W) Quad(ruple) (Q) Four times as many pixels compared to the base resolution, i.e. twice the horizontal and vertical resolution respectively.

List of common resolutions Computer graphics[edit] For the table below, SAR (storage aspect ratio) is based solely on pixel count. It does not take into account PAR (pixel aspect ratio, pixels may be non-square) and thus the DAR (display aspect ratio, the aspect ratio of the actual image that is displayed) may differ. A list of standard designated VGA display resolutions, commonly used in computing and computer monitors, can also be found at Graphics display resolution. Resolutions below HD[edit] HD and up resolutions[edit] Television[edit] For television, the display aspect ratio (DAR) is shown, not the storage aspect ratio (SAR); analog television does not have well-defined pixels, while several digital television standards have non-square pixels.

List of True 16:9 Resolutions | Pacoup.com 2013-01-20Updated to include 4K UHDTV. In an effort to enhance the knowledge of the video-making community, I have compiled a list of all true 16:9 video resolutions, including their associated standard when applicable, as well as when the resolution is dividable by 8, which is useful for limited video encoders. The table goes up to 1080p and includes the common resolution for 27 inch 16:9 computer monitors and Super Hi-Vision. If you’ve ever worked with SD content, you’ll notice that no resolution in here fits the DVD standard. That’s because DVDs were originally made to comply with the NTSC broadcasting resolution, which is a non-square pixel standard using the resolution of 720 by 480 pixels, stretched to accommodate either 4:3 or 16:9 content, never producing a true 16:9 resolution.

Fluid Width Video IN A WORLD of responsive and fluid layouts on the web ONE MEDIA TYPE stands in the way of perfect harmony: video. There are lots of ways in which video can be displayed on your site. You might be self hosting the video and presenting it via the HTML5 <video> tag. <video width="400" height="300" ... <iframe width="400" height="300" ... <object width="400" height="300" ... Guess what. So can't we just do this? <video width="100%" ... Well, yep, you can. <iframe> Video (YouTube, Vimeo, etc.) Our little 100% width trick isn't going to help us when dealing with video that is delivered via iframe. Fortunately there are a couple of possible solutions here. But, but... aspect ratios, legacy content, non-tech users, etc. The above technique is awesome, but it has several possible limitations: It requires wrapper element, so just straight up copy-and-pasting code from YouTube is out. If either of these limitations apply to you, you might consider a JavaScript solution. Adding Vimeo View Demo

Aspect Ratio Calculator (ARC) Use the form below to calculate the missing value for a particular aspect ratio. This is useful, for example, when resizing photos or video. <p><strong style="color: #c00;">You must have JavaScript enabled to use this page. Instructions Enter the values for the original width (W1) & original height (H1) on the left. Formula Say you have a photo that is 1600 x 1200 pixels, but your blog only has space for a photo 400 pixels wide. (original height / original width) x new width = new height (1200 / 1600) x 400 = 300 Note: this is the new, improved version. andrew.hedges.name / experiments / Aspect Ratio Calculator

Creating a Mobile-First Responsive Web Design Introduction We're going to walk through how to create an adaptive web experience that's designed mobile-first. This article and demo will go over the following: There is even more up to date responsive guidance on our new Web Fundamentals site. Why we need to create mobile-first, responsive, adaptive experiences How to structure HTML for an adaptive site in order to optimize performance and prioritize flexibility How to write CSS that defines shared styles first, builds up styles for larger screens with media queries, and uses relative units How to write unobtrusive Javascript to conditionally load in content fragments, take advantage of touch events and geolocation What we could do to further enhance our adaptive experience The Need for Adaptivity As the web landscape becomes increasingly complex, it's becoming extremely important to deliver solid web experiences to a growing number of contexts. However, mobile context is much more than just screen size. View the demo Structure Style Less JS

DVD to MPEG-2 - how? - Mac Forums LOL i always get a kick out of people who have no idea what MPEG2 is. its a VERY VERY CPU intensive compression method. It takes a LONG time to make anything MPEG2 (compared to making something 3ivx etc) its just the nature of the beast. As for taking a DVD off the shelf at Best Buy and bringing it home to edit the videos on the DVD... thats not going to take 10 minutes. VIDEO_TS is a folder containing .VOB and .BUP files etc. To take that VIDEO_TS folder and make it BACK into the original videos is not easy. What do you want to do with the MPEG2 files? Video is not a quick thing, ever.
