(Available for 241P4QPY & 241P4QPYK) 

  How does it work?

‡ PowerSensor works on principle of 

transmission and reception of harmless 

“infrared” signals in order to detect user-

presence.

‡ When the user is in front of the monitor 

the monitor operates normally, at the 

predetermined settings that the user has 

set- i.e. Brightness, contrast, color, etc

‡ Assuming that the monitor was set to 

100% of brightness for example, when the 

user leaves his seat and is no longer in front 

of the monitor, the monitor automatically 

reduces the power consumption down to 

80%.

 Setting

Default settings
At its default setting, (Setting 3), PowerSensor 

is designed to detect the presence of the user 

located between 30 and 100 cm (12 and 40

left or right of the monitor.
Custom settings
If you prefer to be in a position outside the 

perimeters listed above, choose a higher

The higher the setting, the stronger the 

detection signal. For maximum PowerSensor

yourself directly in front of your monitor.
‡ If you choose to position yourself more 

than 100 cm or 40 inches from the 

monitor use the maximum detection signal 

for distances up to 120 cm or 47 inches. 

(Setting 4)

‡ Since some dark colored clothing tends to 

absorb infrared signals even when the user 

is within 100 cm or 40 inches of the display, 

step up signal strength when wearing black 

or other dark clothes.

‡ You can return to the default mode at any 

time (Setting 3).

  How to adjust settings

If PowerSensor is not operating correctly 
inside or outside the default range, here’s how 
to fine-tune detection: 
‡ Press the PowerSensor hot key 
‡ You will find the default position ‘3’ on the 

adjustment bar.

‡ Adjust the PowerSensor detection 

adjustment to Setting 4 and press OK.

‡ Test the new setup to see if PowerSensor 

properly detects you in your current 

position.

‡ PowerSensor function is designed to work 

in Landscape mode (horizontal position) 

only. After PowerSensor turn on it, it will 

automatically turn Off if the monitor is 

used in Portrait mode (90 degree/vertical 

position); it will automatically turn ON if 

monitor is returned to its default Landscape 

position.

 

Note

A manually selected PowerSensor mode 

will remain operational unless and until it is 

readjusted or the default mode is recalled.  If

sensitive to nearby motion for some reason, 

please adjust to a lower signal strength.
