3rd Monitor Not displaying

[aaronbendavis]

I have a lenovo ideapad 310, os is windows 10 and was working perfectly fine with 2 external screens connected, one connected via vga and one connected via an active dvi displayport

Windows 10 decided to do an update and now my 3rd monitor in the display port won’t display visuals.
Windows recognised the 3rd screen and the mouse appears on the screen, i also used a Multimonitor tool to see the screen in preview and it appears their. AMD does not display the screen their either.
Earilier i did an amd update and the monitor worked until the computer restarted and was back to square one.

It runs a dual graphics setup

OS: Windows 10 x64
CPU: AMD A10-9600P Radeon R5
GPU: AMD R6 M435DX
GPU2: AMD R5 Graphics

It's a driver function, try updating GPU driver.

GPU Drivers are fully up to date

Don't just update them, use DDU http://www.guru3d.com/files-tags/download-ddu.html to uninstall them first so they don't keep old settings.

I have had this same issue. My second monitor is a BenQ. No matter what I do, windows will not recognize my monitor if it gets bugged. To resolve it, I have to unplug the power to the monitor for 20 seconds and then plug back in and viola. Not sure if this will help you or not but just wanted to put it out there.
