Video 
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, which is 1024 x 768 for the 15 inch, 
and 1280 x 1024 for the 17 inch. 
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 touchmonitor 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 touchmonitor’s displayed image. These adjustments are 
“remembered” by the touchmonitor. 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. 
On-Screen Display (OSD) 
Four OSD buttons are on the bottom of the monitor. These can be used to adjust various 
display parameters.
