Hi, i know this is old topic but i have same question and i don't unerstand if the answer is just a Why you shoul do that or no, you can't.
Usually i only turn off PC and monitor go black in stand by, but with this monitor still a flashing led that is very annoying... the power consumption is the same for stand by and off mode so for a comfort reason i just turn off PC (so i have not to turn on/off same PC and monitor, turn on one and all go on).
So the question is: can i do this via software?(In the monitor oprtion i can't) or i have to do this via hardware? (like destroy led or black paint it)
You cannot stop the glowing while in active-off mode. I have never heard of any software that could interact with the monitor in the way you want. Just turn the monitor off if the LED is that bothersome. I certainly would not destroy the LED.

Short of just turning the monitor off, no. The manual page 16 shows the power button states.

Why leave it in standby? I turn all of my monitors off at the end of the day.
