Involved Hard- & Software:
Build: Tower PC
Mainboard: AsRock A88M-G/3.1
Graphics Card: HIS R7 250 2GB
Windows: 10 Pro 64 Bit
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.
I have put the BIOS setting to define the Main Graphics adapter to "PCIexpress" -> This is not working.
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.
The PCIe Card is plugged into the right slot of the Mainboard (PCIe 3.0).
The PCIe Card is working 100% perfectly in the AMD dual graphics mode.
The PCIe Card is not broken!
The PCIe Card is aknowledged by Windows (shown as working and installed in devices manager).
The PCIe Card is aknowledged by the AMD driver software.
The APU is working 100% perfectly in the AMD dual graphics mode and solo.
The APU is not broken!
The APU is aknowledged by Windows (shown as working and installed in devices manager).
The APU is aknowledged by the AMD driver software.
The BIOS is on the newest version.
The Chipset Driver is on the newest version.
Windows is on the newest version.
The AMD driver is on the newest version.
Please tell me :/
First: Hit the BIOS back to standard settings. Totall clear the settings back to default.
Second: Save and turn the PC OFF
Third: Plug the HDMI to the PCIe Card
Last: Repeat the configuration of the BIOS with the HDMI cable still plugged into the PCIe Card.
Result: The PCIe Card will STAY PRIMARY and the APU is deactivitad as long as not needed (like in Multi GPU games; there it will be switched on.)
