I just plugged in and installed drivers for my zotac gtx 1070. My main monitor is hdmi and it shows up however my 2nd is Display port and no matter which port i plug it in, it has no signal. They worked just 30 minutes ago when i had my old graphics card in, now only one does. help?

No known reason why this works on occassion AFAIK, but have you tried turning everything off, then turning the monitoring on before powering up your rig?

I assume you've tried different DP/HDMI ports?

It appears there has been a few DP issues with the 10 series cards (didn't know this until now):

Enable/disable legacy boot for PCIe devices if available in your BIOS.

The msi 970 gaming. And i just swapped the displayport for the dvi port and it seems to be working. For some reason the DPs on the 1070 arent working
