Chapter 4 – Operation
Power
To turn the touchmonitor on or off, press the touchmonitor power button once.
The Power Status LED on the bottom of the touchmonitor functions according to the following
table:
TouchMonitor/Computer Module status LED status
OFF OFF
SLEEP PULSING
ON ON
The system consumes low power when in SLEEP and OFF modes. For detailed power
consumption specifications, refer to technical specifications on the Elo website
http://www.elotouch.com
Touching the screen will bring the attached host PC out of SLEEP mode (similar to moving the
mouse or pressing a keyboard key).
To improve reliability and reduce wasteful power consumption, disconnect the AC power cable
from the power adapter when long periods of disuse are planned.
Touch
Your IntelliTouch Plus touchmonitor is factory-calibrated and should not need manual calibration
(unless the input video is not fully scaled to the native resolution, or the touch experience needs
to be calibrated to a specific user).
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 of 1920x1080.
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).
