    Discrete + HD4000 dual monitors failing after Win 8.1 update

      SOLVED

      Steps taken:

      • Updated all drivers to current versions
      • Set onboard graphics to primary in the BIOS.

       

       

      System details:

      ASROCK Z77 Extreme 6 Motherboard

      i7-3770

      AMD HD7880 with latest (beta) drivers.

      Windows 8.1 64bit

      16GB RAM

       

      Monitor connected to HD7880 via HDMI

      Monitor connected to motherboard via VGA

       

      This setup worked fine under windows 8, however it does not work under 8.1

       

      When I unplug and plug the monitor in via VGA it turns on, says "no signal" and turns back off again.

       

      I tried looking through the forums for answers but it's a bit incomprehensible.

      I've tried the intel driver update utility.

      I've tried a manual instal of 15332b whatever that one is (can't remember it was a whole 2 days ago).

      I've tried the drivers from ASROCK's website.

       

      Thanks.
