Hello, I have 2 screens one of them is dvi to dvi which is working, the other one is dvi to dp, and it's not being picked up at all, I updated my motherboard bios, tried changing the pci in the motherboard to legacy and none worked, any idea how to make it work?
 
Ps, i had r9 390 before the 1070 and bother were working fine 
 
Thanks. 

its philips screen and as i mentioned the cable is dvi to displayport

the cable is a dvi to display port , sadly i got no more information about it , 
i did try it on the 2 screens but none of them worked , i want to connect the dell screen to the display port.
the model of it is dell e2214h 
 
Edit1:- yes i did try all the DP ports 

it does work though on the Old gpu , i will buy a new cable and update you.
 
Thanks for the help :)

before i get the 1070 i had 390 and i was using that cable , and when i saw that it did not work on the 1070 i tried it again on the 390 and it did work , anyway , i will get a new cable and hope for the best 

you were right , it was a cable issue.
 
Thanks alot 

Awesome!
