I have a Dell Inspiron 530. I upgraded from xp to Win 7 and cannot get my multiple monitor set up to work. It worked perfectly on xp. When I click on Screen Resolution, there is no choice for Connect to a projector. Nor is there a Multiple Displays box.
I have tried to update BIOS.
I know both monitors work as I have changed the cables and both work independently.
Both monitors are Compaq S1922a and one will work fine, so I'm sure the drivers are there.
I know it's probably something simple that I'm missing, but I'm going mad trying to figure it out!
