Hi All,

I am currently running an R7990 and having trouble getting my monitors to extend my display. The AMD catalyst control sees monitors 4-6 (sometimes monitor 4 works), but is unable to extend the display. It only allows me to swap monitors with active ones. I have 2 miniDP-DVI, 1miniDP-VGA, 1miniDP-DVI\DP\HDMI, and one DVI. Essentially, I want to run 4+1+1.
I have gotten a 4 Monitor setup to work on my old R9 290x using these adapters so Im not sure where the issue is.
 
Solution
Are you sure the 7990 supports 6 monitors?
