    Hello,

    I accidentally changed the control panel settings to display "second monitor" whenever a HDMI cable is inserted. However, the second monitor is blank. Now whenever I plug in my HDMI cable I see nothing at all because my computer is bypassing my screen. How do I revert back to the original "mirror" settings (the "mirror" HDMI setting is when both monitors display the same visuals).

    Hi. Use DDU to remove the old drivers and registry keys, then reinstall the display drivers. That should erase the custom settings that are messed up.
