I now have 2 Sapphire ATI HD 5770s on crossfire, and want to put my second monitor on the second card.
However, when I plug the DVI cable in, I get no image.
How can I fix this?

You guys are funny, with Crossfire enabled, only the primary card can output to a display, unfortunately that's just the way it works, and all your efforts to make an image come through on the second card are in vain, look it up.

Try booting with the first graphics card and then swap to the second graphics card. Just a guess but who never shoots never scores. Otherwise you might want to contact your PC manufacturer (or if its a custom build than contact the graphics card manufacturer)

Tim, Make sure if in Crossfire that Crossfire is enabled in the BIOS. Second, swap the cable arrangement and make the DVI the primary. I have display ports on my machine along with DVI and I found that display port won't come alive until the actual Windows splash screen comes up. In other words, your system may not be recognizing a monitor at all because the HDMI is not sending a pre-windows boot signal. Just a thought.
