I just got a docking station from dell with a Dual monitor option.  TWO DVI-D ports.  However,  my monitors are DVI-I.  I had to purchase some DIV-D to DVI-I adaptors.  Cheap on ebay.   I still am not sure I will be able to hook them up correctly.  Please if there is anything special that I have to do with my Latitude E6400 from dell and my dual monitors, please let me know.  i was hoping I could just plug it in. 

Thanks
