Multiple Monitor trouble

Hey all, I got 2 PCI-e video cards, one in sig then a 6200TC. Windows sees both. My 7800 is hooked up to a 2405 and 2001 and they're workin fine. the 6200 is hooked up to a third 2001 and it's getting a signal of a black screen (getting a signal though).

How do I enable the third one, it's not under the settings tab as a third monitor

Well I uninstalled the nvidia drivers, installed omegas, then reinstalled nvidia drivers and now it's workin. Basicly you just need to get rid of nview and everything will work perfectly.

Gonna include some random words here for future use for searches
