The resolution that an LCD is designed to operate at. An LCD has a native resolution because it has a fixed number of pixels. You cannot use an LCD with a native resolution of say 1,024 x 768 pixels and expect it to display a true resolution of 1,600 x 1,200 pixels. An LCD can be fed with an input signal at a lower or in some cases a higher resolution than its native resolution, but these will typically be upscaled or downscaled respectively, usually with some degradation to the picture quality.
