What is the maximum ECO sensor detection range? Why does the ECO sensor on my monitor not work as intended? The maximum distance is 120cm.
The maximum ECO sensor detection range is 120cm. The ECO sensor uses infrared proximity detection to calculate range based on reflection.
Because infrared rays are subject to interference due to the presence or absence of reflection, if reflected energy is weak it may not register with the ECO sensor. We recommend wearing light colored clothing as much as possible for better detection.
What is ECO sensor of BenQ projector? ECO sensor detects users’ presence in front of the monitor within the set range.
