hi so i was looking to plug in an older dell monitor into my mobo as a second monitor via vga but my system isnt picking it up? the monitor just goes into sleep mode. i then got in touch with someone and they told me it was because my main monitor was plugged into my gpu and to plug the second monitor into the gpu aswell but my gpu has no vga slot so i decided to plug my main monitor into my mobo but then all of a sudden that wouldnt work either so i have it in my gpu but does anyone no how to fix this i really need that second monitor.
mobo: Asus Prime B450m-a
