Does anyone else have the HD5870 and a triple monitor set up? I got everything I thought I needed, but can't get more than two monitors to work. The monitors are Dell 24" ones with all different types of connectors. My understanding was that I could run two monitors through the two DVI ports while the third monitor must be through the DisplayPort. Got back a little while ago with a DisplayPort cable that goes straight from that monitor to the card, but it won't display more than two monitors at a time. In Catalyst Control Center all three displays show up, but the DisplayPort one is disabled. I can't "extend" the desktop to the third without being forced to disable one of the others.
The ATI's documentation that came with the card didn't even have directions for the HD5800 cards on the CD. Just a bunch of manuals for the older cards. :chair:
