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).
