The native resolution of a LCD, LCoS or other flat panel display refers to its single fixed resolution. As an LCD display consists of a fixed raster, it cannot change resolution to match the signal being displayed as a CRT monitor can, meaning that optimal display quality can be reached only when the signal input matches the native resolution. Wikipedia does not have an article with this exact name. ... It has been suggested that Color LCD be merged into this article or section. ... Image File history File links Native-resolution_800x600_on_1024x768. ... It has been suggested that Color LCD be merged into this article or section. ... Liquid crystal on silicon (LCOS or LCoS) is a micro-projection or micro-display technology typically applied in projection televisions. ... Flat panel displays encompass a growing number of technologies enabling video displays that are lighter and much thinner than traditional television and video displays using cathode ray tubes, usually less than 10 cm (4 inches) thick. ... Nineteen inch (48 cm) CRT computer monitor A computer display, monitor or screen is a computer peripheral device capable of showing characters and/or still or moving images generated by a computer and processed by a graphics card. ... Display standards comparison The display resolution of a digital television or computer display can be an ambiguous term especially as displayed resolution is controlled by different factors in picture-tube (CRT) and flat panel or projection displays using fixed picture-element (pixel) arrays. ...

While CRT monitors can usually display images at various resolutions, a LCD monitor has to rely on interpolation (scaling of the image), which causes a loss of image quality. A LCD has to scale up a smaller image to fit into the area of the native resolution. This is the same principle as taking a smaller image in an image editing program and enlarging it; the smaller image loses its sharpness when it is expanded. This is especially problematic as most resolutions are in a 4:3 aspect ratio (640×480, 800×600, 1024×768, 1600×1200) but there are odd resolutions that are not, notably 1280×1024. If a user were to map 1024×768 to a 1280×1024 screen there would be distortion as well as some image errors, as there is not a one-to-one mapping with regards to pixels. This results in noticeable quality loss and the image is much less sharp.

In the mathematical subfield of numerical analysis, interpolation is a method of constructing new data points from a discrete set of known data points. ... It has been suggested that Color LCD be merged into this article or section. ... The aspect ratio of an image is its displayed width divided by its height (usually expressed as x:y). For instance, the aspect ratio of a traditional television screen is 4:3, or 1. ... In mathematics, an injective function (or one-to-one function or injection) is a function which maps distinct input values to distinct output values. ...


Some resolutions work well, however, if they are exact multiples of smaller image sizes. For example, a 1600×1200 LCD will display an 800×600 image well, as each of the pixels in the image will be represented by a block of four on the larger display, without interpolation. Since 800×600 is an integer factor of 1600×1200, scaling will not adversely affect the image. It has been suggested that Color LCD be merged into this article or section. ... This example shows an image with a portion greatly enlarged. ...


Because of native resolution, some people who play computer games refuse to use LCD monitors, since the native resolution is so high that it may cause frame rate issues when playing a game. However, standard resolutions that make up a perfect fraction of the native resolution can look better (e.g. 4 native pixels per pixel of small resolution). This article needs a complete rewrite for the reasons listed on the talk page. ... It has been suggested that Color LCD be merged into this article or section. ... Frame rate, or frame frequency, is the measurement of how quickly an imaging device produces unique consecutive images called frames. ...

Projector Resolution -- Native vs. Maximum (943 words)
That fixed array of pixels is known as the native resolution of the projector.
So for example, let's assume you have a video projector with a native resolution of 1280x720 that is capable of displaying an HDTV 1080i signal.
The conversion of a non-native signal to a native resolution is a process of approximation.
XGA vs SVGA Resolution - PLUS Vision Corp. of America - Corporate Website (726 words)
Resolution is simply the number of pixels (or "picture elements") the projector uses to create the image.
Resolution is usually quoted in two numbers, such as "800 x 600," where the first number refers to the number of pixels from side to side across the screen, and the second number refers to the number of pixels vertically from top to bottom.
If a projector's native resolution is 1024 x 768 (XGA), that means that the actual number of physical pixels on the display device is 1024 x 768.
