Windows – Multiple monitors broken with Windows 10 upgrade

driversgraphics cardmultiple-monitorswindows 10

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 10.18.10.4252
  • 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?

Best Answer

I had the same problem. Also tried reinstalling my drivers, did not work.

This is what worked for me:

  1. Right click "Start" and select "Control Panel" (Open classic Control Panel)
  2. In the right corner -> View by: "Small Icons"
  3. Display
  4. Change Display Settings

Now you will see the traditional display configuration screen.

  1. Select ("black/gray") extended monitor
  2. Make sure "Multiple displays" is not set to "Disabled ..."
  3. Select apply once done for all displays.

Done! :-)

I am not sure if I always used the correct terms; my computer isn't in English.
