I just installed the HD 6450 into my HP Elite 6000 (it was a suggested graphics card on HP's quick spec sheet) and I am using 2 Dell VGA monitors. I wan using the VGA output (which works) and the DVI output through a DVI to VGA cable. ( I have 2 of these cables so the cable isn't the problem) The DVI to VGA monitor isn't being recognized. Please help. Brand new refurbished machine (fresh windows 7 install). If you need any other information please ask.
