I originally had my laptop plugged into a docking station, and then the docking station connected to a monitor; I don't recall whether it was connected via VGA or DVI. I've since moved and no longer have either the monitor or the docking station. I just bought a new monitor, and I can't seem to get it to work.
The monitor is a PnP device. It's connected to my laptop via the VGA port. There are no problems with the connector. The monitor does work fine with two other laptops, but not this one.
Again, the problem is very basic; the laptop does not see that the monitor is there. The monitor displays 'No Signal' and sleeps; it does know that it's connected to something, though. According to device manager, my display adapter is 'Standard VGA Graphics Adapter' and I have one monitor, which is the one built into the laptop, and it's just identified as 'Generic PnP Monitor.' The external monitor isn't listed.
Going into the Resolution dialog, I only have one display listed, 'Generic PnP Monitor on Standard VGA Graphics Adapter.'
I've tried combinations of Fn+F8 and restarting, but nothing seems to work. I've also tried updating drivers from device manager, but it says they're up to date.
