XFX core r7750

installed can't seem to get #4 monitor to come up using dvi port to hdmi, or vga.

will not identify fourth monitor but shows 4th monitor in gray about 50% of regular size to the rest in windows 7, if using dvi tohdmi cable, nothing if dvi to vga cable.
XFXforce.com is under construction and they don't respond to e-mails. any Ideas?

The 4th monitor is there but Greyed out because your card probably cant support all 4 monitors together but 3 monitors. Thanks

I understand but the port doesn't work even by itself, without any other monitors attached? Thanks!
