Question I can't choose my discrete GPU as the primary in the BIOS settings ?

Hi
long story short I have an HP Z230 SFF workstation with an i5 4570 and I have to use my iGPU's encoding capabilities because my discrete GPU does not support any.

So I accessed the BIOS and under advanced tab I activated Intel Integrated Graphics and set its dedicated VRAM and I have no idea why I did this, I also changed Primary VGA Adapter (not sure of the name) from my Nvidia GPU to Intel's HD graphics and as a result the iGPU is considered to be the primary adapter now which means when I turn on my PC it gives me a blackscreen on my monitor which is connected to my discrete GPU, until the PC boots into Windows then I get a picture on my monitor.

This obviously barred me from accessing the BIOS to revert the changes because I could not see what was happening. I did reset the BIOS and managed to access the advanced tab, however I can
no longer see the option to choose my discrete GPU as the primary adapter, it's gone! I can only enable or disable the integrated graphics and set its vram amount.

If I keep it disabled obviously my discrete GPU becomes the primary adapter and my PC boots normally.
The option used to be right below the integrated graphics toggle but it's gone. Is that supposed to happen?
If I connect a monitor to the motherboard and access the bios while the iGPU is enabled will the option reappear?

BIOS version: v01.62 6/10/2019

Welcome to the forums, newcomer!

You could just clear the CMOS and everything should be back to factory settings. See if that helps.

thanks, I did clear the CMOS however the option to choose my discrete GPU is not there, if I enable the Integrated graphics it'll become the primary adapter which is not what I want.

I would try physically removing the dGPU and plug your motherboard's HDMI output into your monitor. Reboot and let it get into Windows using the iGPU.

Once you have that set and fully working, turn it off and then I would put the dGPU back into the PC, and plug a second HDMI from the dGPU to the monitor's second input. Hopefully this will help "re-register" the dGPU. I would assume you can then switch Windows' video input to the GPU, then reboot and hopefully the BIOS will now have the option.

Kind of like clearing the CMOS; you want to get the computer back into the iGPU state and then follow the normal way you would add a "new" graphics card.

thanks, I will try this later for now I don't need to access the BIOS so I let it be until I get a display port to HDMI adapter since the motherboard only offers 3 display ports. I just wonder why clearing CMOS did not solve this obviously my GPU is still recognized and it's functioning.
