I'm having issue with my 3rd monitor. I recently upgraded my graphics card. I have xfx r7870 DD. The Catalyst Control Center detects all 3 monitors but whenever i try to enable (extend/duplicate) the 3rd monitor the system ask me to disable 1 of the 2 working monitors. I also tried using the display settings, no luck! I'm using 2 DVI's and 1 mini display port for the monitors.
My systems has pentium dual core CPU, window vista home premium 64-bit, XFX R7870 DD graphics card.
All monitors are working but it will not let me use 3 monitors at the same time. Thanks for your time. Any help will be appreciated
