Dual monitors go black when Display Port is plugged in
Product: HP 6200 Pro MT
Operating System: Microsoft Windows 7 (64-bit)
I need to convert to dual monitors on a HP 6200 Pro MT PC with Display Port and VGA ports. The computer displays propertly with a single monitor connected to the VGA port. Both monitors go black when I plug in a second monitor via the Display Port.
In reading Internet documentation it is not clear if dual monitors will function from the system Display Port and VGA ports. Forum articles address dual monitors with addition of a discrete video card (Big_Dave 2/4/2012).
Will dual monitors work from the system Display Port and VGA ports? If yes, what procedures are required to make such configuration work? Any ideas on why the monitors go black? Is a discrete video card required?
Any assistance would be much apprecited as I ususally prepare income taxes and do not deal with bytes and bits.
