Just ran a reinstall of windows 7 because of a malware issue, everything is up and running smooth. Before the reinstall, i had dual monitors hooked up and on extended mode. Now, the second monitor is on and in mirror mode, but it doesnt show up in the display menu thing (right click desktop and hitting resolution), only shows my primary monitor. Dual monitor support is enabled in my BIOS (i have an MSI Z97-G45 gaming mobo). I have installed the latest drivers. Confused because i didnt change anything with what ports theyre plugged into or anything.
