second screen is not recognized at startup

Question: second screen is not recognized at startup

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.

But under both setpoints, my Logitech MX 1000 laser mouse and my Windows Ultimate installation work. All energy saving options of the mouse at Windows startup not.

I have currently installed Setpoint 4.80 after the setpoint is not installed. Would be glad, if someone draw USB receiver for the mouse from the port and put back in it. Then I can get the login screen, but the mouse does not work.
