Dual display is dark!

When I start the computer, Dual display is dark.
Dark, Black, Blind…


I updated Windows of my PC 1/12.

One of them, there was a graphics driver “Intel Corporation – Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2 – Intel(R) HD Graphics 4000“.
Perhaps, I think because of this driver was caused to this phenomenon.

So, I uninstalled this driver.
And, I installed new graphics driver from Intel website.

Install later, rebooted my PC.
And I resolved this problem !
