Windows 7: External Monitor connected to Laptop does not turn off

External Monitor connected to Laptop does not turn off

I have an external 4k UHD monitor connected to my HP 8470p laptop. (I project content only on external monitor and my laptop screen is off)

The settings on Windows 7 have been configured to turn off the display after 1min (my laptop is still on and never shut off or put to sleep).

After a min of leaving the system idle, my monitor screen turns off and immediately within a few seconds turns on, a blank screen appears and displays my input source (in my case would blink "Display Port" a couple of times). Then a few seconds later turns off. This keeps looping forever and my monitor never sleeps.

Is anyone else facing this issue or have faced previously and are aware of a fix?

hi welcome to the forum.

I think whats happening is the laptop is turning off the output to the screen but the monitor is trying to search for an input. maybe their is a setting in the monitor itself. a work around would be set a screensaver to blank then the screen would just be a black screen.
