Hello everyone! I'm having some issues getting a 4th display working with my system. I have 3 32" samsung displays in a 3x1 setup and I want to add an additional 24 inch dell monitor off to the side. When I try to enable the display in windows screen resolution settings it will not let me save the settings giving me an error "unable to save display settings".
I have a Radeon 7990 with 4 HDMI to mini displayport connections that work with the samsung tv's but not the dell monitor. I've also tried connecting with dvi and that doesn't work either. Any help would be greatly appreciated.
