Thanks guys, I have tried all suggestions and still black screen.
Here is what is strange about this card. I can log into my desktop with Windows 7 and RealVNC and it shows the correct info for my graphic card and my display. I can go to system preferences and change the resolution and frequency to all available ones that my card supports and it still has a black box on the actually samsung monitor that says "Not Optimum Mode 2048x1152@60Hz" but that is exactly what it is set as. Does anyone have any ideas what the problem might be, I am at the end of my rope on this one and about ready to buy a different card.
