Hook up 2 external monitors to Dell laptop

Specs: Windows 7
I am trying to hook up 2 external dell monitors to my dell 6410 laptop with Windows 7 (on a docking station). This configuration worked great with my old dell laptop running xp. I have the 1st monitor on the vga port and the 2nd on hdmi. when the laptop is closed the pc boots and the startings windows message appears on the 1 screen then transfers to the other screen then shuts off. Windows only sees the 1 screen. If I open up the laptop then windows sees it as a second screen. When in control panel it does not give the option to extend the display if the laptop is closed. Any ideas? Thanks

If the graphics built in to the laptop does not support more than the internal and one external monitor, then that is it, there is nothing you can do about it. Your external monitor probably just mirrors what was on the internal monitor, so you are limited to one desktop area, not an extended area. If it were a desktop, you could easily change or add a graphics card, but on a laptop you are stuck with what they integrated in to it. You can try updating your graphics driver from the Dell site, but I doubt that it will help. You are left with two choices if you need more 'real estate' to work with, one is to get a larger wide screen monitor and choose a high resolution (if your graphics supports it and it does not effect your portable monitor), or get a 'desktop' for working at your desk. A mid tower computer will allow more expansion, typically more speed, and a flexibility you do not get from a portable, plus it can be custom built for your specific needs for only a little more than stock (depending on those needs).

You have to be a little bit crazy to keep you from going insane.

It is supposed to support it, the 1 external monitor is not a mirror, it is a separate monitor so I can move apps to one or the other. Thanks for the info.

The Cloned / Extended / Dual Mode is a feature of the Graphics Chip, also the Driver/Software Packge has to able to inplement the full features of the graphics chip!

Found a fix, it only took both monitors to be connected with hmi cables, on my old laptop I was using 1 vga and 1 hmi.

thanks to all.
