I have a Sapphire HD 5770 and I'm trying to connect 3 monitors.
- 2x DVI
- 1x Displayport
I installed the latest CCC driver but my menu is not the right one. It can only activate two monitors at the same time.
As mentioned in the comments above, you are limited to two outputs on this card when running Windows XP. Sounds like it's time for an upgrade!
