I got three (3) displays connected to my graphic card (an ATI Radeon HD 6870), My display are connected as follows: one (1) on the VGA port, one (1) on the DVI port and another one (1) in the display port using a display port to HDMI adapter.
Whenever I try to extend my display on a third one using the Catalyst Control Center (A marvel of technology, in my humble opinion...); it throws me this intricate dialog box saying the following: "To extend the desktop, a desktop or display must be disabled."
I am very happy indeed that it tries to help me, but, it really doesn't... (I don't blame it though, it's just trying to do it's job.)
So, what am I to do, to make it work?
Thanks... I really hope we can find an answer to this, really, troubling problem.
i don't want to use Eyefinity.for the moment i just want to extend them( i tryed eyefinity but i get the same problem). The monitor with the DP to HDMI is my main display, when i'm looking in the Screen resolution option i can extend a second monitor but when i try to do the same with the third one i got this : "Unable to save display settings.". My adapter is a DP to HDMI from StarTech. apparently this adapter is Passive.
Just for the record, in order to use three (or more) monitors from a single graphics card, you must enable Eyefinity.
Nope - eyefinity is about monitor grouping. I toogle my eyefinity display group for gaming, then disable it in windows.
With Eyefinity off, I have three separate usable screens (i.e., if I put something on the left screen and maximize it, it fills just that monitor)
With Eyefinity on, I have what windows thinks is one big screen across three monitors. The taskbar extends across all three, and if I put a window anywhere and maximize it, it fills all three. That's how the games work.
Eyefinity would also allow me to use two of the monitors in a group and retain one as separate, if I wanted.
