Looks like locking on is impossible on this laptop config A10-5745M + R7 M260, and it has only two P-States, when locking in at max turbo, the iGPU has no power left and the display will stop output and eventually crash, this cpu is a beast at max turbo but the dgpu in linked and cannot be directed as display output, I have tried many times with some Japanese tool to reduce max turbo frequency for allowing some space for iGPU, also underclocking, and trying to lock it on Catalyst Manager. Any solution would be really appreciated.
Edit; The APU has three p-states.
