I have 2 LED HD Monitor's and a pavilion by HP, H2n63AA#ABHP Pavilion P7-1534. I cannot find anything to make both my monitors work because the DVI in the back of the pavilion has 27 slots. Any help on what to purchase to make this work. I bought a DVI-A adapter and a DVI-D chord and connected the adapter to back of monitor then connected the chord to the adapter and to the pavilion but no screen display. Help
