  1. Monitor won't sleep after inactivity timeout


    Hoping someone can help me here as I'm running out of ideas. I am running Windows 10 21H1 and having an issue with monitors not going to 'sleep' after the inactivity timeout. This occurred on my previous mainboard and CPU and continued after I replaced them recently. I have gone as far as resetting Windows (reset & keep my data) but it still happens. - Acer KG271U (Displayport) & Benq Zowie XL2730 (HDMI) - 5 minute screensaver set to "blank" - 15 minute monitor inactivity to turn monitors off - All chipset drivers and everything I can think of updated (monitor drivers included) What happens is after the 5 minute timer, the blank screensaver comes on no problem. After the 15 minute timer, the screens wake instead of going to sleep/standby. The 5 minute timer then kicks in again and monitors go to blank screensaver, before again waking at the 15 minute interval. I have confirmed it's the sleep timer that is waking the monitors as if I set the screensaver to 1 minute and the screen inactivity timer to 2 minutes - at the 2 minute mark the screens wake. If I disable screensaver and just have inactivity timer enabled, the screens will turn black for ~1-2 seconds and then turn on again. They don't ever reach standby mode though where the power light is amber. I thought it might have been a USB device causing the monitors to wake before the timer is up, but occurs every time at the 15 minute mark without fail. Never before, only after it tries to put the monitors into standby mode. If I use nircmd to run nircmd monitor off - the monitors go to sleep/standby as expected and are only woken when I move my mouse / tap on the keyboard. Any ideas?

    I am running Windows 10 21H1 and having an issue with monitors not going to 'sleep' after the inactivity timeout. This occurred on my previous mainboard and CPU and continued after I replaced them recently.

    I have gone as far as resetting Windows (reset & keep my data) but it still happens.


    - Acer KG271U (Displayport) & Benq Zowie XL2730 (HDMI)
    - 5 minute screensaver set to "blank"
    - 15 minute monitor inactivity to turn monitors off
    - All chipset drivers and everything I can think of updated (monitor drivers included)

    What happens is after the 5 minute timer, the blank screensaver comes on no problem. After the 15 minute timer, the screens wake instead of going to sleep/standby. The 5 minute timer then kicks in again and monitors go to blank screensaver, before again waking at the 15 minute interval.

  4. Monitor won't sleep after inactivity timeout

    unattended sleep timeout

    Hi,

    Thank you for posting your query in Microsoft Community.

    I will assist you with this.

    Specifies the duration of inactivity before the system automatically enters sleep after waking from sleep in an unattended state.

    For example, if the system wakes from sleep because of a timed event or a wake on LAN (WoL) event, the sleep unattended idle timeout value will be used instead of the

    sleep idle timeout
    value.

    Hope the information was helpful.

    Thank you.
