    Multiple monitors broken with Windows 10 upgrade


      I have a HP ENVY 17-3200 (switchable graphics: Intel HD 4000 + AMD Radeon HD 7800M) with a triple monitor setup:

      • Laptop's builtin LVDS 1080p display
      • DisplayPort WQXGA display
      • DisplayPort 1080p display


      This configuration worked under Windows 7, 8, and 8.1.  After upgrading to Windows 10, only 2 displays work.  I have the latest drivers.


      • Intel driver
      • AMD driver 15.7.1 (15.200.1062.1002)


      I suspect this may have something to do with the fact the 4000's drivers only support WDDM 1.3 and the AMD drivers support WDDM 2.0.


      How do I get all 3 monitors working again?
