Hi guys,

I was looking for answer for months, but I couldn't find.

The problem i have is that i use 280X on crossfire with triple monitor.

But with crossfire enabled, i can only use the primary graphics card.

(My primary and secondary graphics card has 1 HDMI, 1 DVI, 2 Mini DP ports)

Knowing that, I have connected 2 monitors by DP, and 1 monitor by HDMI (on the primary gpu).

But my pc detected only 2 monitors like 1 monitor by HDMI and 1 monitor by DP.


So in case the DP port is the problem, i connected the disconnected monitor with DVI, and it showed the same result.

With DVI connected, HDMI didnt work.


So the question is, how can i connect those three monitors to one gpu?

+ Ive heard that DP connectors have passive / active connections. Is that a problem? If its the problem, what active dp connector do i need? (my three monitors all same, they have 2 HDMI, 1 D-SUB.)

+ Picture of the GPU connection : Image

Thanks for your help.
