This is a known bug in some of the latest drivers. It only happens if you upgraded from a previous version
I just had the same problem myself, only had options in the software for Gaming, Video, Relive and System
Fixed it by running the AMD clean uninstall utility (http://www2.ati.com/drivers/amdcleanuputility.exe) and then re-installing the driver. Now have Display instead of Relive.
