Appendix A – Native Resolution
An LCD panel’s native resolution is its width and height measured in number of pixels.
In almost all cases, an image displayed on an LCD monitor will look best when your computer’s output
resolution matches the LCD panel’s native resolution.
For computer output resolutions at non-native resolutions, the monitor will scale the video to its panel’s
native resolution. For smaller input video resolutions, this involves “stretching” the input image in the
X- and Y-dimensions to fit the panel. For larger input video resolutions, this involves “compressing”
the input image in the X- and Y-dimensions to fit the panel. An unavoidable byproduct of the scaling
algorithms is a loss of fidelity when the computer’s output video image is scaled by the monitor to fit
the display. This loss of fidelity is most apparent when viewing feature-rich images at close distances
(for example images containing small-font text).
