I've always used a extended monitor along with my main one, using both dvi's on the card going to each monitor and then just set one as primary in Nvidia panel.
Just changed from my GTX780 to a 1070, and with more modern cards I only have 1 dvi on the 1070, plus 3 dpi's and hdmi, so I thought I'd connect the main screen with a hdmi cable as it has a hdmi on the monitor, and the extended on just keep usong the dvi cable, that doesn't really work well, the extended monitor seems to show the boot sequence so ie post screen and so on once it's booted through all my icons are still on the main screen but it's really poor quality, the extended one is fine, its not the cable, if I use the main screen on its own with dvi or hdmi cables quality is fine. Its like if you use both the dvi still seems to have priority over hdmi, can any help please?

Main Monitor has dvi & hdmi connectons.
Extended has dvi & vga connecions.
Card has 1xdvi, 1xhdmi, 3xdpi's.

Do I use dvi to dvi for main monitor, and get a either a dpi/hdmi to dvi cable for the extended monitor??
 
Make sure that in the nVidia control panel under change resolution that "Output dynamic range" is set to full not limited.

Unfortunately you can't really change which connector is the primary one used for boot screen - if it matters you'll have to find a way to have that monitor plugged into whichever port that is on the GPU.
 
Check that the resolutions of both monitors are correct.

You can go into Display Settings and set the primary monitor. That won't affect the BIOS display but will affect Windows.
 
what motherboard do you have? I had a similair experience, and turned off a setting in my asus motherboard, z77 sabertooth then on my asus hero and it fixed the problem.
I'm on my laptop at work if you need me to look up the setting let me know, it was something that allowed to run old tech or something.
