Dual display with laptop
Posted on 2009-04-08
Hi, I have a DELL laptop connected to a docking station. I connected a monitor to the docking station via a VGA cable and I was able to extend my desktop fine between the laptop monitor and the additional external monitor.
I now want to add 2nd external monitor via the DVI card that is also on the dock. When I connect the monitor XP does not recognize the 2nd external monitor. When i go into the display settings there is no detection either. If I close the monitor on the laptop then XP recognizes the 2nd external monitor (the 1st external monitor via the vga cable now becomes the primary monitor) and I am able to extend my display between the 2 external monitors.
But I need to use all 3 monitors, the laptop monitor, and the 2 external monitors must be all extended across eachother. Is this possible with a docking station or perhaps the video card does not support this?
