Hi, my external display lost ability to fall into sleep after inactivity timeout is reached. It just turns to black screen, apparent the display is active (I don't use the blank screen screensaver). The display only switches to standby if I unplug the signal cable. Withal it was able to switch into full standby earlier. So something had to change.
I did walk through monitor menu to find if there's some settings for power saving mode, there's none.
Connected via HDMI. Have searched a bit for this problem and found only this be closest to my problem: windows 7 - Monitor doesn't sleep on power off - Super User but the topic doesn't have a solution for me (I don't see any DPMS or power off options, probably for that BIOS is in UEFI mode).
powercfg /availablesleepstates gives this report
Any resolution on this issue?
