hello
i just got a new computer, and for some reason my games get a major drop in fps when i plug in a second monitor
the only fix i have found to this is to mirror both monitors and then set it back to extend
any fix for this?

specs
OS : windows 10
cpu : i5 6400 @2.70ghz
gpu : gtx 1070

also i noticed this

does this mean anything?
i'm not sure what any of this means so anything will help

first image doesnt work, not sure if its relevant to the second but i dont notice anything standing out there

He forgot a letter in the link, it's working now.
And eh, I have no second monitor so this might be completely wrong, but shouldn't both monitors have the same gpu? In case there's an option for that.

that's what i thought, but i never checked on my old computer when it was working fine
whenever i go into nvidia control panel, it doesn't even detect the second monitor
both are using DVI cables so that may be a problem some how before i was using 1 dvi and 1 vga
