I am installing a Vista Home Premium Dell laptop with a Targus ACP50EU USB2.0 Docking Station With ideo. The intention is to have all peripherals (printer, separate desktop monitor, etc.) connected to the docking station.
I want to get the laptop screen and the desktop monitor to show the same display. I've got the separate monitor working off the docking station (VGA port) OK, but it only shows the Vista desktop background pattern - no cursor, no icons, no taskbar, no system tray.
I've checked Control Panel>Display Settings, and to my surprise it shows *three* monitors, labelled as follows:
1. Generic PnP monitor on NVIDIA Geforce 8400M GS ("Extend desktop to this monitor" is ticked but greyed out, "This is my main monitor" ditto) 2. (Default monitor) on NVIDIA Geforce 8400M GS (The icon for this is smaller than the other two and it's marked "Not active") 3. Generic PnP monitor on Targus USB2.0 VGA docking device ("Extend desktop to this monitor" is ticked).
If I go to monitor 3 and tick "This is my main monitor", the situation that I've described above is reversed. i.e. the desktop monitor shows my complete desktop - icons, cursor, etc. etc. and the laptop monitor just shows the blank Vista background.
Please can you explain how I can get both displays to show the full active image? I'm flummoxed!
PS: I don't know whether this is relevant, but when I first installed the docking station drivers, Vista reported that they were incompatible. So I downloaded the Vista drivers from the Targus website. That file uninstalled the old drivers and installed the new ones. Since then, the Vista sidebar has stopped working and when I boot up the computer I get an error report "Error loading cmcnfgu.cpl. The specified module could not be found". Are these two problems perhaps related?
