The system consumes low power when in SLEEP and OFF modes. For detailed power consumption
specifications, refer to technical specifications on the Elo website
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 monitor when long periods of disuse are planned.
Touch
Your touchscreen display 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).
