The first monitor is working fine over HDMI, and the OS (win7) detects the second monitor fine, but the monitor itself is saying that it's not receiving input. I've tried using the 970 drivers from the disk, and the newer version from nvidia, and nothing gives any video signal to the second monitor. The second monitor is also using a VGA adapter (I tried the one from the box and my old adapter), and I tried both DVI ports and nothing works, although the HDMI screen always works fine.
I did notice that everything was only on the VGA screen before I installed the drivers, if that's worth anything.
This is the model I have http://www.zotac.com/products/graphics-cards/geforce-900-series/product/geforce-900-series/detail/geforce-gtx-970/sort/starttime/order/DESC/amount/10.html
