A display’s native resolution is its width and height measured in number of pixels. Generally, for best performance, an image
displayed on this monitor will look best when your computer’s output resolution matches this monitor’s native resolution.
For computer output resolutions at non-native resolutions, the monitor will scale the video to its panel’s native resolution. This involves
stretching or compressing the input image as needed in the X- and Y-dimensions to fit the display’s native resolution. 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).
Your touch display will likely not require video adjustments. However, for analog VGA video, variations in video graphic card outputs may require user
adjustments through the OSD to optimize the quality of the monitor’s displayed image. These adjustments are “remembered” by the touch display.
Also, to reduce the need for adjustments for different video mode timings, the monitor correctly scales and displays some of the video industry’s most
common video timing modes. Refer to the technical specifications for this monitor at http://www.elotouch.com for a list of these Preset Video Modes.
