I just got a computer built. I have a dual monitor set up using samsung monitors syncmaster p2770. I have a hdmi hook up in one monitor which works perfectly fine. But the hdmi connection to the 2nd hdmi port on the pc (located near the dvi/d input) does not show the screen. Is my graphics card broke or motherboard not working properly? Do I need to take this back? I hate to have just built a new computer with a part not working
