    Ok I have no effing clue what happen... I just rebooted my computer and then started having issues displaying on my primary and secondary monitors. At first primary monitor was not displaying but second was working... then vice versa... now I can't get second monitor working... I have no idea what to do...

    I did the detect windows... recheck cables all work...nothing is hardware malfunctioning so its something in the software

    You can see two monitors are detected in spaces but nothing displays

    Are they plugged into one video card?

    If not then it could be a failed graphics card?
