Is 4K twice is good as 2K? Is it different resolutoin Ultra HD? Is p 1K? What do all these random numbers mean? One of first numbers you'll see when you're shopping for a new TV -- right after the screen size and the price -- is the resolution. Unfortunately, it's one of the more confusing numbers too. Here are some common questions you might have about resolution, along with our quick answers.
Resolution, in terms of TV hardware, refers to the number of pixels that compose the picture on the TV. A single pixel, or tg picture element, consists of a tiny dot on the screen.
There resoution numerous resolutions found on flat-panel TVs. Older TVs, and many inch models sold today, have a million or so pixels p. More recent and slightly larger TVs typically 49 inches and smaller have a little over 2 million pixels p.
Even newer and bigger TVs typically 50 inches and above, although numerous smaller sizes too have 8 million stxndard 4K Ultra HD. And the newest, largest and most ridiculously resolutjon TVs have over 33 million pixels 8K. You'll have to look very closely, or whip out a magnifying glass, to discern each one. Resolution is one of the most common specifications used to sell TVs, partly because "4K" and "8K" sound really high-tech and impressive.
However, resolution is not the most important ingredient in picture quality. Just because a TV has higher resolution than another, doesn't always mean it's looks better. It might, but not always, vt for reasons that have little to do with resolution. Wtandard TV with better high dynamic range HDR performance, a better overall contrast ratio or better color will look better than one that just has more pixels. That said, it's still worth understanding the various resolutions used by TV makers and others.
Here's a bit more, ahem, detail. The most common resolution for new TVs is 4K. Since it's unfamiliar to many people, it's also the source of the vast majority standar the confusion about TV resolution. One problem is that 4K means something different whether you're talking about a TV in your home, or a projector in a theater.
Technically, "4K" means a horizontal resolution of 4, pixels. This is the resolution set forth by the Digital Cinema Initiatives. Because movies vary in aspect ratio, which refers to the exact shape of the rectangle of screen, no vertical resolution is specified. So yes, the pedants are correct. However, it doesn't matter.
Amazon and most TV makers, all of which just use both. This shows the relative number of pixels in each of the major resolution formats.
Not actual size of what is industrial automation engineering this is a chart not a visual representation ks it is standarx scale if you click on it.
From largest to smallest: 4K Cinema, in 1. Since the pixel difference is 13 percent and it's nearly impossible to see even larger differenceswe'll file this under "why does anyone care? Sony's home 4K projectorson the other hand, are actually 4K. The best picture I've ever seen in a theater was a 4K projector with iis. If you're talking about TVs, it's twice the horizontal and vertical resolution of 4K TVs: 7,x4, This isn't a cinema resolution yet, at least not outside of the experimental stage.
We're starting to see 8K TVs hit the market, but it's going ehat be many years before tf resolution is common. Right now you what is self- rimming sink find 4K content in many places. If you have a PC, most video staandard from the last few years can render games at 4K, with varying degrees of success.
We'll have to wait until ATSC 3. For cable and satellite there are some options from some providers, how do the plate tectonics move this is currently only a couple of channels of movies and documentaries. Before "4K" became common, you'd almost never see "2K. It's 2, pixels wide, and again, no vertical resolution is specified by the DCI. But now that "4K" has gained traction as a term used to describe TVs and content, "2K" is becoming increasingly common as shorthand for the p standars used by most HDTVs, as well as Blu-ray.
It's not technically accurate, but that didn't stop "4K" from becoming more popular than "UHD. Remember how we talked about digital cinema resolutions only specifying the horizontal resolution? Well TVs, on the other hand, stzndard historically used the whzt to describe resolution going back to the glass tube days. So p is the vertical resolution. Nearly all HDTVs have an aspect ratio of 1.
This is another source stajdard confusion, since decades of TV discussions have talked about vertical resolutions, and then all of a sudden we're talking about "4K TVs," which refers to the how to tell renata summary resolution. Don't blame me, it wasn't my idea. That means p is not "1K.
That said, most people don't call p 2K; they call it p or Full HD. By the way, i is the same resolution as pbut no modern TV is i. Roughly half the number of pixels of p. It's rare to find a TV that's p anymore. This goes back standar the initial HD transition at the turn of the century.
Standxrd if you're wondering why your TV doesn't say "p" on those channels, check this out. In the computer world they use an incomprehensible and shockingly un-user-friendly jumble of letters to describe resolution.
Well, not "shockingly" since these are computers. Look, I'm a computer guy, building my own PCs since the early '90s, and even I can't tell you what half these letters mean. I can understand that initially they were implemented to reso,ution things easier, but we've got so many resolutions and combinations what to get brother for christmas now they're just annoying.
The rest, you can dive into and print yourself a cheat sheet from this. Fortunately, the only time most of you whag come across this letter goulash is if you're looking for a cheap data projector or ztandard computer standatd. There are also computer monitors that have unique resolutions like 5K 5,x2, or ultrawidescreen aspect ratios with crazy resolutions like 3,x1, There are so many variations we couldn't hope to cover them all. When you boil it all down, here's the takeaway: Your current TV unless you bought it in the last few stansard is HD, p.
Someday you might have an 8K or even 10K TVbut that's a l-o-o-o-o-ng way away. Here's where we remind you that more pixels doesn't necessarily mean a better picture.
There are other aspects of picture quality, such as contrast and color, that are far more important than resolution. In the future, resolution might become irrelevant.
Technologies like MicroLED separate size and resolution, so your future inch bedroom TV will have a radically different resolution than the inch living room TV, as opposed to now where they'd both be 4K with different size pixels. And one would be a projector. Thanks to advancements in video processing, though, this won't matter.
They'll all look sharp and detailed. Update Feb. It has been updated to reflect new information and advancements.

TV screen “resolution” always refers to the total number of pixels that make up the picture on the TV screen. The higher the screen resolution, the more detail the picture can produce. Today’s TVs have from a few hundred thousand pixels to 33 million pixels on a screen. Jul 03, · 4K or p = x – is commonly known as 4K, UHD or Ultra HD resolution. It is a huge display resolution, and it is found on premium TVs and computer monitors. p is called 4K because the width is close to pixels. In other words, it .
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.
This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight". One use of the term display resolution applies to fixed-pixel-array displays such as plasma display panels PDP , liquid-crystal displays LCD , Digital Light Processing DLP projectors, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pixels creating the display e.
A consequence of having a fixed-grid display is that, for multi-format video inputs, all displays need a "scaling engine" a digital video processor that includes a memory array to match the incoming picture format to the display.
For device displays such as phones, tablets, monitors and televisions, the use of the term display resolution as defined above is a misnomer, though common. The term display resolution is usually used to mean pixel dimensions , the maximum number of pixels in each dimension e. In digital measurement, the display resolution would be given in pixels per inch PPI.
In analog measurement, if the screen is 10 inches high, then the horizontal resolution is measured across a square 10 inches wide. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters e. The eye's perception of display resolution can be affected by a number of factors — see image resolution and optical resolution.
One factor is the display screen's rectangular shape, which is expressed as the ratio of the physical picture width to the physical picture height. This is known as the aspect ratio. A screen's physical aspect ratio and the individual pixels' aspect ratio may not necessarily be the same. An example of pixel shape affecting "resolution" or perceived sharpness: displaying more information in a smaller area using a higher resolution makes the image much clearer or "sharper".
However, most recent screen technologies are fixed at a certain resolution; making the resolution lower on these kinds of screens will greatly decrease sharpness, as an interpolation process is used to "fix" the non-native resolution input into the display's native resolution output.
While some CRT-based displays may use digital video processing that involves image scaling using memory arrays, ultimately "display resolution" in CRT-type displays is affected by different parameters such as spot size and focus, astigmatic effects in the display corners, the color phosphor pitch shadow mask such as Trinitron in color displays, and the video bandwidth.
The size of the invisible area somewhat depends on the display device. Some HD televisions do this as well, to a similar extent. Computer displays including projectors generally do not overscan although many models particularly CRT displays allow it.
CRT displays tend to be underscanned in stock configurations, to compensate for the increasing distortions at the corners. Interlaced video also known as interlaced scan is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth.
The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon. The European Broadcasting Union has argued against interlaced video in production and broadcasting.
The main argument is that no matter how complex the deinterlacing algorithm may be, the artifacts in the interlaced signal cannot be completely eliminated because some information is lost between frames.
Despite arguments against it, television standards organizations continue to support interlacing. New video compression standards like High Efficiency Video Coding are optimized for progressive scan video, but sometimes do support interlaced video.
Progressive scanning alternatively referred to as noninterlaced scanning is a format of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame each image called a video field are drawn alternately, so that only half the number of actual image frames are used to produce video.
Many personal computers introduced in the late s and the s were designed to use television receivers as their display devices, making the resolutions dependent on the television standards in use, including PAL and NTSC. Picture sizes were usually limited to ensure the visibility of all the pixels in the major television standards and the broad range of television sets with varying amounts of over scan. The actual drawable picture area was, therefore, somewhat smaller than the whole screen, and was usually surrounded by a static-colored border see image to right.
Also, the interlace scanning was usually omitted in order to provide more stability to the picture, effectively halving the vertical resolution in progress. One of the drawbacks of using a classic television is that the computer display resolution is higher than the television could decode. Many users upgraded to higher-quality televisions with S-Video or RGBI inputs that helped eliminate chroma blur and produce more legible displays. These computers used interlace to boost the maximum vertical resolution.
These modes were only suited to graphics or gaming, as the flickering interlace made reading text in word processor, database, or spreadsheet software difficult. Modern game consoles solve this problem by pre-filtering the i video to a lower resolution. For example, Final Fantasy XII suffers from flicker when the filter is turned off, but stabilizes once filtering is restored. The computers of the s lacked sufficient power to run similar filtering software.
It was the standard resolution from to around Some emulators, at higher resolutions, can even mimic the aperture grille and shadow masks of CRT monitors. In this image of a Commodore 64 startup screen, the overscan region the lighter-coloured border would have been barely visible when shown on a normal television.
Dithering is used to overcome color limitations. Further information: List of common resolutions. The following table lists the usage share of display resolutions from two sources, as of June The numbers are not representative of computer users in general. In recent years the aspect ratio has become more common in notebook displays. When a computer display resolution is set higher than the physical screen resolution native resolution , some video drivers make the virtual screen scrollable over the physical screen thus realizing a two dimensional virtual desktop with its viewport.
Most LCD manufacturers do make note of the panel's native resolution as working in a non-native resolution on LCDs will result in a poorer image, due to dropping of pixels to make the image fit when using DVI or insufficient sampling of the analog signal when using VGA connector.
As far as digital cinematography is concerned, video resolution standards depend first on the frames' aspect ratio in the film stock which is usually scanned for digital intermediate post-production and then on the actual points' count.
Although there is not a unique set of standardized sizes, it is commonplace within the motion picture industry to refer to " n K" image "quality", where n is a small, usually even integer number which translates into a set of actual resolutions, depending on the film format. As a reference consider that, for a around 1. From Wikipedia, the free encyclopedia. For screen sizes typically in inches, measured on the diagonal , see Display size.
