    My monitor won't wake on system boot up


    My desktop is a Dell Inspiron 3881, Windows 10. Recently my monitor started failing to wake up when booting up my PC. The flashing light came on fine, but the monitor was just black and the usual Dell logo didn't appear. I changed some settings to try to resolve it. That only worked slightly as the monitor indicator light stopped flashing after leaving it for some time and stayed on, with the monitor screen now in grey, so I switched it off and on again. This time it started fine. I did this for the next couple of weeks and was happy to wait for it to kick in. However, I reset my power setting

    computer won't boot but has power

    Kursah, that 6 steps are granted it always boots at the 6th step (sometimes at the 4th) and I have to remove the ethernet cable every time otherwise I'll have to do countless steps, that's a fact. I do not have Wake On Lan set.

    My monitor won't wake on system boot up

    Dual monitors not waking from sleep

    Hi all,

    I'm having issues where my monitors won't wake from sleep in a dual monitor setup. This only occurs after waking them from a sleep state, and they work fine when booting up my PC from scratch.

    I have tested both monitors in a single monitor setup and the issue goes away completely as they wake from sleep just fine when only using a single monitor. This issue only seems to occur when using both monitors simultaneously.

    I have tried the below steps to no avail to remedy the issue:

    • Changed the DisplayPort cable
    • Uninstalled graphics drivers with DDU and reinstalled them again
    • Made sure Windows update was completely up-to-date, including any optional drivers
    • Made sure there were no unknown devices in Device Manager
    • Turned Link State Power Management under PCI Express in Power Plan settings to off
    • Completely formatted my PC and reinstalled Windows 11
    None of these steps have resolved the issue.

    Any assistance provided will be much appreciated!
