So I have an Asus Prime H270-Plus and I have an Asus nVidia GTX 1060 3GB. I want to add another monitor with the internal graphics, I have it enabled in the BIOS (the iGPU multi monitor) but the intel graphics doesn't show on my PC. I have an intel i7-7700k and whenever I try to install intel drivers the installation fails, even though the drivers say my CPU is supported, and the in-store graphics command center and it doesnt show integrated graphics at all.
That is because when you insert an add-on graphics card, it typically disables the onboard graphics. Best to check with Asus on their bios settings to see if they allow both the Intel and nvidia to be active concurrently.
