16:9 is probably the ASPECT RATIO of the monitor, and NOT the resolution.. unless that monitor has a 1600x900 capability, but seeing as you gave so much information about things .. ..
That card works perfectly well here with a DELL U2312HM and NO screen adjustments needed either, it just fits full screen, no problem at all, no configuring, no messing around ..
You need to adjust things as per the AMD GPU Scaling FAQ page and try again using the CORRECT resolution and refresh rate for that monitor .. and install the monitor drivers too, it does help ..
