Windows 7: second graphic card dont send output signals

02 Nov 2012   #1

Windows 7 Ultimate x64
second graphic card dont send output signals

Im running an crossfire with HIS Radeon HD 6850 as the first card and a ASUS HD 6870 DirectCU card as the second card.

Im trying to add a third screen to my setup, I could not get the screen to work only with my first card (it only showed up as grey and dident let me activate it) so I bought a new card to crossfire it with my old one, but now I cant get the outputs to work, they simply do not display on my screen nor do the screen find them.

also worth mentioning is that the first card outputs are: 1 x DVI-I, 1 x DVI-D, 1 x HDMI, 1 x DP
and the second cards outputs are: 2 x DVI-I, 2 x DP

I am using the two DVI outputs now
