Windows 10: Dual Monitor - Extend these displays not working (duplicate view only)?

Windows 10: Dual Monitor - "Extend these displays" not working (duplicate view only)

After upgrading to Windows 10, the "extend displays" function is not functioning well on my PC (ASUS monitors; ATI Radeon HD 2400 PRO display adapter). I have tried disconnecting & reconnecting and have tinkered with most related settings I am aware off, but all in vain.

I found a crude workaround accidentally. I restart my PC from the log in screen until the dual monitors start in the extended view (I have no idea how this works!). It usually takes about two to three restarts.

I hope someone can explain what is going on and how I can fix this so that I don't waste time every day!

I'm running into a problem with the backlight of my second monitor going out after installing build 10565.

ATI Radeon HD 2400 PRO?
wow that's little old videocard.

But what operating system are you upgrading from?
did you reinstall your drivers? I know there is no win10 version, but I saw there is a win8 version, so I guess you could try to reinstall that and see if that fixes it.

Reinstalling the driver seemed to have worked! Thank you so much.
