One thing I noticed that's particularly odd. However, other information reporting tools, namely HWInfo and GPU-Z are able to provide quite substantial information about the discrete card. HWMonitor detects the IGPU but not the discrete card. Also downloaded and ran a bunch of info reporting tools. Tried Catalyst and the most recent Crimson Beta for legacy graphics hardware. In safe mode, I have used AMD's cleanup utility and DDU to remove all drivers and driver software, and installed fresh drivers from AMD driver website. By the way, there is no option in BIOS to do that either, neither is there a 'fixed' or 'dynamic' switchable graphics option as I have seen in some screenshots. However, doing so only made the PC use Microsoft Basic Display renderer, even though the discrete GPU was present and working properly (as stated in Device manager). I tried disabling the IGPU to somewhat force the PC to use the discrete GPU. I have set power settings, both in Power options (Advanced > Switchable graphics) and in AMD's Catalyst Control manager, to Maximum performance. In fact, under Graphics options in Settings, the IGPU is seen as both the power-saving and high-performance GPU.

As the title implies, I am having trouble getting the discrete GPU to work as expected (switching to handle resourse-intensive tasks). I own a Samsung Series 7 700Z5A laptop with two GPUs a discrete AMD 6770M (chipset labeled as 6600M and 6700M) and an integrated Intel HD Graphics 3000. Will do my best to keep it concise as possible.
