So when i have a monitor plugged into my main gracphics card and one plugged into my igpu, the one in the igpu doesnt show up as a monitor. I went into my bios and changed the main display or something to my internal gpu and then when i got on my computer it showed both. So when my igpu is set as default, it shows both monitors. But when my non internal gpu is set as my default, the igpu does not show. If i set my igpu as my default, is it going to take away from the performance of my non internal gpu? I know this may be a bit hard to understand but i have gotten myself in quite a tangle.

I only have the option to plug a single monitor into my gpu. I would have to use my igpu to use 2 monitors.
