Question Displayport conflict with DVI ?

[Insane666999]

Hi,

I have GTX 1070 graphic card with two monitors, when I connect one monitor to displayport everything is fine, but when I add second monitor with DVI port a problem occurs that I'll explain below.
The problem is that when computer put monitors to sleep after 10 minutes, my first monitor screen that connected with Displayport goes off but backlights stays on.

Things I have done but didn't worked :
Updated and downgraded different display driver versions.
Updated Graphic card bios version to : 86.04.1E.00.89
Updated Displayport firmware with nvidia graphics firmware update tool for displayport.

Display to dvi typically works poorly or not at all. Active conversion may be required to make the issue go away but those types of cards are $$$. Can't use any other port on your monitor?

I'm not trying to convert, adding second monitor with DVI affects first monitor connected with DP.
