I need to know why one of the three monitors I have connected to my 5850 card isn't coming on. each monitor I connnected into both DVI ports didn't work. Am I doing something wrong or are both DVI ports dead. And yes, I have the Displayport to DVI dual adapter connected.
dvi - hmdi shouldnt matter at all, thats a simple through connection.
I assume your dvi connectors are working fine with 1 screen? and the dvi-hdmi, and displayport all work fine when in solo mode?

If you just use the displayport - dvi adaptor in your card, does it work (1 screen obviously).
My main LCD is now run off the displayport - dvi adaptor and it works fine. That is, I have my sapphire active adaptor plugged into the pc via usb, and plugged into the gpu via displayport, and the dvi output is connected to my main screen.
If you can't get a display off that then there must be an issue somewhere.
IMHO, I think both DVI ports are bad. I swapped adapters (hdmi-to-dvi, dvi-to-D-sub) nothing because I noticed that between those two connectors that I mentioned just now, the male connector teeth are different and I those it might have made a difference, but it didn't, plus someone on Newegg purchased the same card and had the same issue as well.
