NWill Posted February 21, 2013 Report Share Posted February 21, 2013 (edited) I bought my third and final display today. I'm using an AMD HD7700 series with eyefinity. Two of the monitors display just fine but when I try to extend to the third, it says I must disable one of the other two. This was with one HDMI connection and two MiniDP to HDMI connections. The two monitors that are currently enabled are the two MiniDP-HDMI. I also tried switching the HDMI connection to DVI. I keep seeing something about how it must be connected a certain way but nothing about it telling me to disable a monitor?? I don't know shit about this stuff, I've been able to get away with just plugging things in in the past... Thanks Edit: The more I read it looks like many have had same problem. It looks like I need an "Active" adapter for the third to work. Edited February 21, 2013 by NWill Quote Link to comment Share on other sites More sharing options...
gillbot Posted February 22, 2013 Report Share Posted February 22, 2013 Yes, you need an active adapter. The cheapest are DP to VGA. Quote Link to comment Share on other sites More sharing options...

NWill Posted February 22, 2013 Author Report Share Posted February 22, 2013 I already had all HDMI wires ran through the center post on my mount so I ended up with the following: (1) DP/HDMI dongle -> Monitor One (2) DP/DVI dongle -> DVI/HDMI adapter -> Monitor Two (3) DVI/HDMI adapter -> Monitor Three I would have just bought two DP-HDMI active adapters but of course MC only had one so I had to get a DP-DVI and DVI-HDMI adapter Quote Link to comment Share on other sites More sharing options...
