I have a VGA monitor and an HDMI monitor but my GPU has only 1 HDMI port and 3 DPs. I know I can just buy an adapter but would the negative impact of having my VGA use my Rzn5 5600g and my HDMI use my GPU be noticeable? I would only use my VGA monitor for chrome, discord, etc. and the other one for gaming
I would assume you would have to choose GPU bifurcation from BIOS (just find whatever iGFX settings there is and set it so that it enables you to run integrated while there is dedicated GPU installed, so it does not disable it). Probably though, you would be better of using only one GPU and if you planned on using 5600G, why not just get AMD GPU, because they likely work better together in this kind of setting where you try to use both iGPU and dGPU.
