Which HD7850 do you have ? Club3D CGAX-7856M6 ?

For a HD7850 card to be able to support more than 2 screens the Eyefinity Feature needs to be enabled. You do that by using a Displayport Output. OS needs to be WIN Vista or newer.

When using Screens with Displayport Input you can use Passive Adapters / Cables to connect from Card to Screen. (Although we always advise to use at least 1 active version, because in practice that seems to work better)

When using Screens without Displayport Input you need to use Active Adapters / Cables to connect Screen 3/4/5/6.

The first 2 are always natively supported so they can be connected with passive adapters at all times, although it will of course also work with Active Adapters.

Passive Adapters:

CAC-1100 = Mini DP to DVI Passive Adapter



CAC-1101 = Mini DP to HDMI 1.4 Passive Adapter



Active Adapters:

CAC-1152 = Mini DP to DVI Active Adapter with Eyefinity Support



CAC-1170 = Mini DP to HDMI2.0 Active Adapter with Eyefinity Support
