If your Mini12 has 2 monitors DO NOT uninstall Inter Arc Control or Intel video drivers. If you do this the Mini 12 will be unable to detect the 2nd monitor and will simply mirror the primary monitor on to it. The Intel uninstaller will also uninstall the Intel Driver & Support Assistant.
The only way to get the secondary monitor back as an independent monitor is the reinstall Driver and Support Assistant, and then let it detect, download, and install the Arc Control software. Once all this is done the secondary monitor will be detectable and will work OK.
