    Displayport goes weird by resuming monitor from sleep.


    Hi,

    some days ago I installed AOC G2460VQ6 75hz monitor with a displayport cable. I saw in windows settings that It is correctly set to 75hz. Unfortunately, with a frequency of 1/3 times, monitor, after resume from sleep (not pc suspension mode, only monitor), will look strange (see picture below).

    I reinstalled nvidia driver with ddu, bios and vbios updated to latest versions. All is updated.

    Os.: Windows 10 1809 (couldn't test If this issue represents also with 1803)

    GPU: Asus strix gtx 970

    Nvidia driver: 416.34

    Thanks.

    Fall creators update Displayport monitor won't go to sleep

    Dual monitor setup on an intel nuc d54250wykh.

    Main monitor via displayport (2560x1440 @60)

    2nd Tv via HDMI (1920x1080@60)

    monitors are set to turn off after 10 min in power options.

    computer sleep is disabled as i need it to be running 24/7 .

    both monitors sleep after 10 min timeout period or after the pc is locked but the monitor on displayport wakes up immediately afterwards and then goes back to sleep immediately and the wakes immediately and
    the cycle continues forever.

    the second monitor stays asleep.

    gpu (intel hd5000) and chipset drivers are latest.

    it started with the fall creators update. no problems before this.

    i have tried disabling usb selective suspend and pci link state power management to no effect.

    i have removed all USB devices(except mouse and keyboard)- makes no difference. have tried different mouse and keyboard- same problem.

    I have run sfc/scannow (no issues detected)

    Have run power troubleshooter no issues there.

    the weird thing is that some running applications change this behaviour.

    eg.

    if i remote desktop into this pc from a different pc the computer shows lock screen as it is supposed to and if i disconnect from remote pc the monitor turns off and doesn't go into that on off loop.

    if i open reddit windows 10 subreddit page in chrome (does not work in IE or edge) and leave it maximised the the monitor goes to sleep when it is supposed to. (doesn't work if it is minimised).

    i haven't come across any other webpage that has this behaviour.( the reddit windows 10 page puts a constant 3% load on the GPU)

    I suspect all this has something to do with the new GPU performance monitors in task manager.

    Displayport goes weird by resuming monitor from sleep.

    Displayport computer not fully sleeping or waking up

    Hi - I have 2 monitors. when I connect them via HDMI it is fine (but my graphics card only has 1 HDMI). It has 3 display ports so I am trying to use those. when I try to connect the displayports it works fine but then when you sleep the computer it doesn't
    fully sleep (the LEDs remain on but all the fans and everything stop) and when you try and wake it, it will not wake up.

    However, when you sleep it and then unplug the displayport connections it goes fully to sleep (lights go off) and you can wake it up again.

    Any ideas how to fix?
