I have this weird problem.

I use a 2nd monitor to extend my desktop. When I walk away from my computer, I lock my Windows session. After I return and unlock my Windows session my 2nd monitor goes dark.

I tried to enable my 2nd monitor under display settings, but it goes dark again. Only a reboot will fix this, until next lock/unlock.

What is going on?

How to fix this?
