I'm sure you heard this question a million times, still i cant find an answer.
I have a HD7870 with on HDMI one DVI and 2 MDP ports.
My monitors are connected as follows.
1 HDMI 1 DVI and 1 MPD with an amd recommended active dongle.
However, i got the same problem as i had with a passive dongle. All 3 monitors are recognized but i can only have two of them active at a time.
Am i missing any driver or so?
Setup is working when i connect my third monitor with a passive MDP->VGA dongle.
I have been searchin for hours. But all threads i find tell me to use an active dongle which i do.
Pleaaaase help me
