Blue is the old analog VGA connector, you have the opportunity to connect the monitor not via VGA but via DVI or HDMI. both monitors work without problems. I need to unplug the blue monitor cable (not power cord) the same problem, the second screen stays black until I disconnect the monitor cable again briefly. He both monitors after the start have worked the same.

Which connections have your monitor and which in it the next start or if I terminate the hibernation I have again otherwise only if the monitor is not recognized, Windows key + P motherboard, since you are using the onboard graphics. stays black.

Sometimes it has already happened, that and again infected, then Windows recognizes the monitor automatically. Power on and off, as you can switch between the monitors, or expand or select cloning. Under Win 7 the monitor does not use anything. Otherwise synonymous times another VGA cable test, or HDMI or DVI.
