I have two monitors connected to it, once DVI to HDMI, where it is from msi and my operating system is Windows 10 Home. Last time, reinstalling Windows helped, My graphics card is a GTX 960 gaming 4G, however, I did not like that to last.

I also reinstalled video card drivers, also works fine. It is not synonymous with the HDMI cable. The screen and has not changed anything. Great works, and once HDMI to HDMI, which is not possible from today.

I changed it, but it did not produce any results.
