We were planning to use 6 monitors. We bought two FirePro W700. So totally we had 2x4 Display Port. We are trying to install 6 Monitor that using DVI port and we already bought 6 DP to DVI Cable Converter. After install everything we found that only 1 monitor had display, the other 5 no display. we were trying to duplicate display but it will pop up ERROR: unable to save display setting.Under AMD catalyst > creating and arranging dekstop - all monitor detected. try one by one monitor and cable converter all working fine. How were we do wrong ?
