We have recently completed the purchase of a graphics card Radeon HD 7850 EYEFINITY 6. We find that 5 flat 6 we want to connect can see but the sixth never works, the problem is not the TV because if we change the cable works correctly. When we go to the configuration of the resolution (Windows control panel) display all appear to us as “off the screen” and black; if we are clicking on them and mark it as “Extend these displays” all but one of them work the following message appears: “Unable to save display settings”.
We use Windows 7 x64 and AMD Radeon driver Crimson Edition Software version Display Driver 16.15.2211. The screens are connected by HDMI i this adapter: http://www.pccomponentes.com/adaptador_mini_display_port_a_hdmi_calidad_4k.html.
Club 3D comment from me that I have from the third screen MiniDisplay have to use active ports. They not sure if I’ve mentioned above are or not.
The computer is a Dell Precision Tower 5810 BTX Base
