Hi!

 

Involved Hard- & Software:

Build: Tower PC

Mainboard: AsRock A88M-G/3.1

Current state:

My PC-Sytem is using the APU as main graphics adapter. It is Only using the PCIe Graphics Card in Multi GPU Mode, while gaming.

What I want:

Define the PCIe Graphics Card as the main Graphics Adapter, so that I can plug in my HDMI Cable into it's HDMI slot and use it on the desktop and in every program.

Problem:

I have put the BIOS setting to define the Main Graphics adapter to "PCIexpress" -> This is not working.

Problem description:

1.1 Although I have defined the main graphics adapter to PCIe, the following happens: When I stick the HDMI cable in the HDMI Port of the PCIe Graphics Card, the screen turns/stays black.

1.2 When I stick the HDMI cable in the HDMI Port of the Mainboard, the screen is shown, because it uses the APU graphics.
