Is there a way to avoid Dell monitor continue to display Power Saving message when PIR sensor turns off screen

[Ragziesoft]

This is not an issue of the PIR-Sensor module. It actually works beautifully. However, the Dell monitor i am using has a feature that displays a moving window(screen saver) with the message that "no input detected, will turn off monitor in 5 minutes". This is an unwanted message which needs to be disabled. When the PIR sensor turns off the screen it should go blank and not display the power saving message. Any ideas how it can be disabled.
Thanks
