    Solution and ROOT CAUSE of BLACK SCREEN Issue

    Gosa

      Hello everyone,

       

      This weekend I dedicate only one hour to hardware solution I have found on internet. Why I say hardware, because after I don know how many updates of graphical driver, reinstalling windows, updating bios I had enough. I suspect on my monitor.


      For all you people that have black screen issue, ROOT CAUSE: DVI connector on mainboard (pin 16 - HOTPLUG DETECT)

      is waiting from monitor signal If > +2.4V Monitor EDID data available, ≤ +0.4V no monitor available.

      After applying correction to my DVI cable, monitor immediately enable DVI, and picture appears.
