mobo:Asrock b450m pro4-f

cpu:Ryzen 5 3400g

discrete gpu: GTX 750ti

I was using the onboard grapics of the 3400g for a while now and decided to try my old gtx750ti, I plugged it in and it worked even nothing is changed in the bios.

While I'm about to download the driver for the GTX 750ti and planning on using DDU, suddenly my monitor blacked out saying it cant detect signal from the source.
I transferred my connected cable to the onboard graphics without resetting still nothing.
So I reset the pc and it has display when connected to the onboard graphics.
but when I try to use the discrete GPU, it doesnt work. Monitor only says no signal is detected.

is my GTX 750ti dead? or do I have to disable the igpu to use the discrete gpu?

Please help thanks!

You shouldn't have to disable the iGPU. I'm currently using both Vega 8 and a discrete graphics card.

So, you weren't changing anything and the display just blanked out? Odd.

Try playing around with the Primary Video Adapter in bios (ext for the 750 connection, int for the 3400G connection).
