The '''native resolution''' of a [[liquid crystal display|LCD]], [[LCoS]] or other [[flat panel display|flat panel]] [[computer display|display]] refers to its single fixed [[Display resolution|resolution]]. As an [[liquid crystal display|LCD]] display consists of a fixed [[raster image processor|raster]], it cannot change resolution to match the signal being displayed as a [[cathode ray tube|CRT]] monitor can, meaning that optimal display quality can be reached only when the signal input matches the native resolution. An image where the number of pixels is the same as in the image source and where the pixels are perfectly aligned to the pixels in the source is said to be ''pixel perfect''.<ref>AfterDawn.com - [http://www.afterdawn.com/glossary/terms/native_resolution.cfm Native Resolution]</ref>
 
While CRT monitors can usually display images at various resolutions, an LCD monitor has to rely on [[interpolation]] (scaling of the image), which causes a loss of image quality. An 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 (image)|aspect ratio]] (640×480, 800×600, 1024×768, 1280×960, 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 [[bijection|one-to-one]] mapping with regard to pixels. This results in noticeable quality loss and the image is much less sharp.
