Hi I cant activate eyefinity with 3 monitors (aoc i2367fm)
i have sapphire active adapter for mini dp but i cant activate all monitors at same time (max two)
my hd 7990 has 4 mini dp and only one dvi , my monitors have only hdmi and vga .
Theese are the connection between card and monitors
mini dp---- hdmi
mini dp---active adapter----dvi to hdmi
dvi-----hdmi
as i just said before i can connect max 2 monitors , in catalyst control center seems that the 2 monitors are connected by hdmi even if i used active adapter , the screen that i cant connect is that connected by active adapter but if i try to exted to desktop Windows stop me with an error message, i tried to connect each monitor at a time and they work all.
sorry for bad english , i'm italian :ange:

Because you need an Active Adapter for DP to HDMI as well as DVI.

I dont know what DP-HDMI adapter you already have, but it needs to be Active. In terms of signal, DVI and HDMI are the same, both require active adaption.

Just get another of those, as well as a DVI-HDMI adapter to hook up the computer currently running on the DP-HDMI connection.

so the problem is the connection between mini displayport and hdmi ? using another active adapter and dvi to hdmi it will be running fine ?
