4 x ViewSonic 2452mh Monitors (
4 x Cable Matters 101019-10 mDP to HDMI cables

I've built a new system with the goal of attaching 4 1080p monitors via 7850 card.
I've disabled onboard graphics via UEFI.
Just downloaded the AMD Radeon Software Crimson Edition Display Driver version 16.15.2211
CCC sees all four monitors yet restricts me to pick two only to configure.

Ideas?

Nothing? Not even a dumbo? As in, "We already answered that one!"

Hi LeLeuPaon,

Please be aware that for any multi monitor setup using an Eyefinity card with Mini DP outputs but NON DP monitors like the Viewsonic panels, you can connect two of the monitors with passive mDP to HDMI adapters. The remaining monitors need to be connected with active mDP to HDMI adapters since only two of the outputs on the card support Dual Mode DisplayPort (DP++) which natively convert DP to HDMI.
For the other outputs, active adapters are required.

Club 3D advises the CAC-1170 mDP 1.2 to HDMI 2.0 Active Adapter for the best results: link to product page

Thanks for the help. I exchanged the four monitors I had bought for DisplayPort versions and everything works fine.
