I bought 1070 and adapter.
I hope to configure, 1070 only for mining and internal GPU ( Celeron N3150) with HDMI output for TV and decode h264.
Can I configure it in to the BIOS (as indicate by JaredKaragen) or in windows 7?
I bought Gigabyte GTX1070 gaming, I hope it is quite.
Thanks
You choose in the BIOS usually if you want onboard or onboard or PCIE graphics selection; but I do not know if this support is added in your BIOS.
Most motherboards will hide the onboard video from the OS when it's using a PCIE (external) graphics.... I am unsure if it works the other way around so you may have good results. nothing but to try.
You will see the high intensity mining side effects on your second display adaptor if it does indeed work alongside an external gpu.
