I would just go back to useing the vga if it's createing this much of a problem. Dvi is technically a better signal type , but its visually identical to vga. Vga uses electrical signals while dvi uses digital signals , but it comes out the other end on the monitor the same.

But if you want to continue useing the dvi cable then just disable the monitor that isn't being used. Hit the identify button and it tells you the number of what monitor your useing , then disable the one thats not in use. And as far as the graphics you need to set it to settings that your monitor supports , it will say in your monitors instructions or on the web if you type in it's exact model in a search engine.
