Laptop with dual switchable graphics, cant use the main GPU

I recently purchased a brand new Aspire E15 E5-553G-T03K laptop after having a world of problems with my Asus one. I specifically chose this machine for the Radeon R8 M445DX 2Gb graphics adapter.

 

No matter what settings I chose the system only wants to use the built in 512Mb R5 adaptor so it is slow as hell with low resolution.

 

How can I force it to only use the dedicated graphics adapter for everything and disable the other one?

 

I have downloaded the latest Catalyst software 18.2.1 which has a world of confusing switchable graphics options for individual apps but it still defaults to the build in card.

 

Additionally the software now tells me that it is a R7 M340 adapter and not the R8 M445 as it says on the machine.

 

My resolution is terrible if I go above 1366x768 (which my 7 year old laptop can do).  Please help, I want to use the hardware this machine came with and disable the crappy R5!
