    how do you blank your screens (Windows 10) ?

    I just wonder if and how you guys are turning off your powerful (and power-hungry) displays when you launch some long MC or other job on your Windows 10 system ?

    On most modern PCs w/ Win10, sleep has been phased out and now even just manual (NirCMD) or timed (Power Settings) screen blanking puts the system in 'Modern Standby' which causes traditional apps to be suspended (incl. MC Background transcodes etc.).

    Apparently, no workaround, except setting the Screen OFF timer to never and manually switching off the display when going out for a walk and your system does some heavy computing.

    Other ideas ?

    Is this a choice by the system admin? A custom config?

    I have not checked the latest build of W10 but our systems still have the option to put the display to sleep.

    I just set my display to turn off after 1 minute (not sleep, just turn off). I started running a process to see if it would stall. After the screen turned off, I waited a few minutes, and looked at the state of the process. It ran while the screens were off.

    Re: how do you blank your screens (Windows 10) ?

    Hmmm, I need to dig further as on my system, there is definitely a Windows System Log event saying

    "The system is entering connected standby
    Reason: Idle Timeout."

    at an unexpected time when background services were transcoding stuff.

    but Sleep timer is set to Never, so only display off could cause this....

    Will check further on MSFT forums...

    Re: how do you blank your screens (Windows 10) ?

    That message merely indicates that it's going into the specified power saving mode. It's not going to sleep. It's turning off the screen but the rest of the system is still running (Modern Standby). The background tasks should continue to run. I'll dig a bit more into this myself and see if I can reproduce it.

    In general MS applications downloaded from the store will pause when in standby, as will most desktop applications. Background tasks should continue to run. Windows may be throttling down 3rd party background tasks after the final phase of entering Modern Standby. But the processes should still continue to run.

    Re: how do you blank your screens (Windows 10) ?

    So I'm running a transcode in the background. The screens have turned off, but the background transcode is running (the light for the media disk is blinking as it normally does for a transcode).

    Out of curiosity, is the option to pause background transcoding turned on? If it is, try turning it off and seeing what happens. Just a thought.

    And the transcode completed while in standby.

    Re: how do you blank your screens (Windows 10) ?

    Thanks for the time taken testing this. I certainly need to narrow it down myself.

    I reckon it's a bizarre thing, I can't seem to repro at will myself, but there is defintely a change in behaviour compared to Win7; I get these unexpected paused processes when the system goes to standby also with apps like TMPGEnc, etc.

    From what I uderstand with Modern Standby it's that all traditional Windows apps are suspended, and that only Store apps are allowed to run and do things like download email, download things etc. if the system allows ('connected standby')

    Re: how do you blank your screens (Windows 10) ?

    Today I launched a long BG render, exited MC (leaving the BG services running) and went away a couple of hours.

    When I came back, the screen was off (as expected, the 'turn off the display' is set to 20 min) and BG render instantly resumed when I reactivated the system...it had been suspended for about 2 hours minus 20 minutes...matching that 'entering connected standby' in the Windows Log....

    Since this doesn't seem to be a popular issue, I guess one or more of the following is true:

    - MC/Win10 users run systems that do not support 'modern standby'

    - MC/Win10 users have disabled 'modern standby' on their capable systems (via registry key)

    - MC/Win10 users never leave their computers doing long BG transcodes (with MC exited)

    - MC/Win10 users never let their display reach the 'turn off the display' timer limit (or have set the timer to 'never', leaving the display permanently on even when they're away for long)

    - I'm the only one bothered by this issue ;-)

    Otherwise I'd like to hear how users deal with this ?

     

    Question to MC developers: I assume there is an API via which processes can tell Windows: 'please don't suspend me when you put the system in "connected standby"' - if such an API exist, why not use it in the BG task processes ?

    Re: how do you blank your screens (Windows 10) ?

    My solution to this issue is that I simply turn the monitors OFF using the supplied power switch, works every time. Geeked

    Re: how do you blank your screens (Windows 10) ?

    Makes sense, of course

    (Unfortunately, I use one of my displays as USB3 hub for keyboard, mouse, tablet, etc. so I need to keep that one powered on)
