I turned on my computer today and the first thing that happened was a notification telling me that my amd graphics card could be updated. During downloading, I restarted my computer. When my computer restarted I went through troubleshooting and it reinstalled what needed to be. Now my 2nd monitor doesn't work. When I go to screen resolution, I can see that my main monitor and my 2nd monitor are detected, but when I try to "extend the desktop to the display" and hit accept, it will always go back to disconnect this display. Does anybody have a solution to my problem? Also both my monitors are connected to one graphics card. I don't know if this matters but my 2nd monitor is a Hyundai L90D and my main is a HP S2031.

 

 

edit: I ran a troubleshoot and it says Microsoft Teredo Adapter #2 is not working. Everytime i let troubleshoot try its solution of installing w/e is needs to, it fails. I don't know if this has an effect. Troubleshooting also found a problem with my PnP device (which is my Hyundai L90D monitor i assume), but that's all it says.

Do you happen to have system restore enabled? If yes, please try using this Windows function to go back to a date where it was still working properly. Another option also is to rollback the previous driver in device manager.
