    Monitors are blank after wakeup


    When I wake up the system from sleep, the monitors are blank.

    The keyboard does not show activity - its LED indicators, such as Caps Lock or Num Lock, do not light up when pressing the respective keys.

    If I soft reset the system, the same thing happens. I have to forcefully turn it off, by keeping the Power button pressed for a few seconds, and then turn it on again.

    How can I troubleshoot this issue?

    :)

    Hi,

    Thanks for the update and response.

    I suggest you to reinstall the monitor drivers form the manufacturer website and check if it helps. Follow the below steps for the same.

    • Press “Windows Logo” + “X” keys on the keyboard.
    • Click on “Device Manager” from that list.
    • Search for the Monitor driver from the device list, right click on it and then select “Uninstall”. On the un-installation window, if you have an option: “Delete the driver software for this device” you may select that
      and then remove the corrupted drivers from the computer.
    • Follow the on-screen instructions to complete it and then restart the computer if prompted.
    Refer the below link for the same.

    Monitors are blank after wakeup

    monitor goes blank

    hey, i have a samsung 22"ws and an 850xt. 1 gig of ram and an old xp3200. Every time I watch a movie in powerdvd or media player i can get some of the way through it and then the monitor goes blank and it acts like the cable is not even hooked up. After that I have to reset. Atitool temps are fine throughout on vid card and mobo temps are good as well. I was just wondering if anyone may have a suggestion at to what it may be. Thanks.
