Latitude E5430, Docking Station and Monitor dilemma - Can anyone help?

Hello all

I'm having some problems in attempting to get two monitors working with my docking station. They are both VGA outputs, which I've attempted to connect with various DVI adapters but haven't been able to get either working with the DVI interfaces.

Having tried the combinations mentioned I'm wondering if it's just not possible to use both monitors (obviously can connect 1 via the standard VGA output on the dock, but had bought the additional monitor specifically so could utilise 2).

Any ideas or advice would be greatly appreciated.

Thanks

Michael
