You need to first post the exact Make & Model (Serial Number if possible) of your Laptop including the AMD APU you have installed.
You need to install the APU AMD Driver which automatically installs both the R7 and R8 Graphic Drivers.
If you install your Laptop's Support Graphic driver it will show correctly the Discrete GPU card you have installed which is 100% compatible and customized for your laptop.
AMD generic Laptop drivers most of the time incorrectly shows the Discrete GPU in Device Manager in the laptop. Instead it will show the Family of the GPU card installed but the Driver will work and be compatible.
Sometimes the Discrete GPU card is still supported by AMD with Driver Updates but the APU (Processor with Integrated Graphics) may not be supported with AMD driver updates. Thus if you install the latest version for your Discrete it might be incompatible with your APU Intergrated Graphics. That is why it is important to post the Make & Model of your APU processor.
