AMD Radeon HD7870
3 Samsung 22" S22C350H
1 DVI to HDMI
1HDMI to HDMI
1 Mini DP with 1 Sapphire Active MiniDisplay Port DVI-D connected with DVI Dual Link to HDMI Cabel
Setup works, but after some Minutes the Monitor on the Sapphire starts to flickering. I Changed the cables and also the Monitors ( no change in behavoiur )
Any ideas? could the Sapphire Adapter not working properly?
Thanks a lot
