I am trying to run my DVI monitor and my HDMI TV on a Galaxy GeForce GT 610 that has 1 DVI and HDMI ports. What is happening is if I plug both cables in neither of the displays will work but if I pull one of the cables out with the other still attached whichever device was left plugged in works fine. Can this video card work with both cables attached? If so, how do I get it to start operating correctly? My system has an Athlon 64 X2 Dual Core Processor, 3.00 GB of RAM, and a 300W power supply (replacing with a 550W) and an OS that is Windows 8.1.
