My monitor has stopped going into power save mode. After whatever interval I have set for the display to turn off in windows, the display turns black but the backlight is still on and the power light is blue, instead of turning the backlight off and the power light turning orange.
I have it connected via display port to my motherboards intel hd4000. I've tried updating the drivers, and rolling back the drivers and trying to connect it via hdmi through an hdmi>dvi adapter as well as dell's "powernap" program which does nothing.
If I disconnect the Displayport cable, it will display the no connection message on screen, and after 5 minutes actually goes into power save mode (backlight off, power button orange). This behavior would suggest a software/drivers issue but I've tried searching as best as I can, but people seem to have the opposite problem of their monitors not coming out of power save mode.
