pretty much we both had the exact same problem but his graphics card was a radeon 5670 and my is a 5770 he had 1 main screen and then 2 outer screens that were same but different size than the middle which is how mine is set up.
this is my setup
middle monitor connected via dvi -> into vga converter -> then into pc
right monitor connected via dvi
then left monitor connected via dvi -> into active display port adapter -> into pc
My pc knows the screen is connected and i can scroll over to the left and then back to the middle so my pc knows that the screen is connected but my screen is not producing a image is it because i have a bad active display port?
thanks for that info nobody ever told me about that but i have concluded that the display port i have bought is corrupted i unplugged all my screens exept the display port and still the screen doesnt work so now im getting a friend to go out and get it right now so ill still be here http://www.microcenter.com/single_product_results.phtml...
