I have a Saphire Radeon HD6950 with 2x DVI, 1x HDMI, 1x DisplayPort. I have a monitor plugged in to each port and tries to extend my desktop over all four displays. I have succesfully extended it to three of them but when I chose the fourth in Catalyst Control Center it tells me that one of the displays need to be disabled to extend to the new monitor.
According to http://support.amd.com/en-us/search/faq/151 my graphicscard should support 6 displays if there are enough ports.
Is there any special setup I need to make to do this or what can be the problem?
thank you in advance
