Plug the non working screen into the card that has the working screen.

If you have 2 dvi cables and your cards are like my brothers, you have to use the hdmi to dvi adapter that came with the card.

When you run crossfire, all the monitors plug into the primary card, top one I believe, and the second card is used only for extra horsepower.

I have DVI on the upper card and tried HDMI on the bottom one.

Try DVI AND HDMI on the main card not on both.

Im fairly sure with crossfire the second card does not need screens to work in crossfire. Maybe if you have more than 3+ screens you need to use the second cards display ports

Corret +1 I'm sorry but Op you must look carefully at what we are telling you

Don't use Both cards Only the main card needs to have the DVI +HDMI on the SAME CARD not the CROSSFIRED ONE LEAVE IT ALONE !

Like Instructed Please use the TOP CARD only
