Hi all,



We have two differnt models of laptops, both use the same model docking station. The docking stations contain both VGA and DVI-D inputs. In case one with laptop type one, we dock the laptop, both screens are connected, one via VGA and the other via DVI-D, and both work to extend desktop or duplicate desktop accross two screens. Swap the laptop to type two and only the screen connected via VGA works.



Laptop type one has for what I can see an Nvidia display adapter / Graphics card, laptop type two has an Intel HD 3000 display adapter / graphics card.



Idont know how we can make this work, this is only to suit when in the office, when working remotley away from the office, the laptop is a laptop.

Are you also trying to use the laptop screen at the same time as a 3rd display?

CYaBro: Are you also trying to use the laptop screen at the same time as a 3rd display?

I think CYaBro is on the right track in that it may be a limitation of the display chips.  Maintenance tasks like a BIOS update or graphics driver update may help.

If you are trying to get the laptop display plus both external displays working, have a look at the following FAQ page.  It doesn't include the HD3000 in the list of chipsets that supports 3 displays.

ou may be able to get the two external displays working by closing the lid of the laptop (first set the machine not to go to sleep when the lid is closed) so that it (should) stop using the laptop display and just use the two external displays.

Fairly sure the HD3000 only supports dual display, thus if the laptop display is still used, you'll get that + one external.
