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.

The network diagnosis brings the message the initially suspected virus scanner also knows PC2. "PC2 is not a valid host name". If it was actually an update, there would still be an option

For no apparent reason, I do not come now on this calculator. Now I suspect in any Windows Update the respective PC zurückuck BEFORE the update

What could that be like (PC1 = Vista / PC2 = XP) the cause of the situation. I have not knowingly changed or renamed anything, and must I proceed now?

What can I do to help? Many people have simply deactivated the "basic graphics" above NVIDIA Quadro FX 880M (internal standard card at Dell).

Hello and welcome,

what are you writing here now? Have him connected to the TV and possibly a walk to the computer store of your trust. It can indeed the graphics card standard VGA mode still available.

I think now I'll go here ... if it uninstalls drivers. (Nvidea was too lazy to do it manually.) Hello, but I'm blind because lappi monitor is faulty and tv is not recognized So now I have a program with the graphics card the monitor is defective.

Okay then ask or 'Graphics on board defective'. Now I have to somehow use cmd or something like the standard graphics driver to do things in the blink of an eye ...... Depending on the age of the laptop, is it worthwhile to plug this monitor into the laptop?
