Elo TouchSystems 3243L User Manual page 16

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.
To keep the product operating at an optimum level please limit the product usage cycle to 18
hours for every 24 hours:
Usage duty cycle:
18 hours on per 24 hours
Elo recommends using the Content Management System or O/S scheduling settings and/or
EloView commands to manage duty cycle. This will enable power savings and trouble free
operation throughout the life of the monitor.
On-Screen Display (OSD)
Four OSD buttons are located on a wired control box. These can be used to adjust various
display parameters.
