    How do i make amd radeon 7400M my primary display adapter?

    Hello, i recently upgraded my windows 7 to windows 8 professional 64bit and after that my primary display adapter became intel graphics 3000 HD and my other display adapter amd radeon 7470 HD shown code 43 error. I rolled back the intel display adapter, which now is Intel HD Graphics Family (Microsoft Corporation - WDDM 1.2) and installed catalyst control center which made the code 43 error disappear.
    I went to check it again and i noticed that now I have intel graphics 3000 HD again and no error on my the amd one.Click image for larger version

    However if i go to screen resolution, on advanced settings i notice my laptop is still not using the amd graphic card.
    How do i change it?

    With mismatched (different manufacturers) video cards your best bet is to install the driver offered by the manufacturer of the PC. That driver is custom made for the switchable graphics to work correctly. Installing the two separate drivers like Intel and then AMD/ATI may not work correctly. I'm lucky my laptop has an AMD APU so my switchable graphics are AMD/AMD. I can install the latest Catalyst CC and everything works as intended.
