[SOLVED] why is the onboard graphics not working?

[puddlejumper6999]

i upgraded recently to
Asus PRIME B450-PLUS
Ryzen 3 3200g w/ vega 8
16gb 3200mhz gskill aegis
XFX RX 580 XXX GTS 8GB

and only got the onboard to work as a secondary monitor once. i shut down for the night and since then it has not worked. ive reset bios and cleared cmos but nothing changes it. setting the modes to:
IGFX : enabled
PCIe prefered

or:
IGFX mode: Hybrid
PCIe prefered
have done nothing. in the device manager the vega 8 graphics device reports code 43 but i cant find what that is supposed to mean. is the IGFX mode for 1 time use with descrete graphics or integrated only?

You cannot do hybrid crossfire or Sli-mode with integrated graphics.
You will need another xfx rx 580 to display on 2 monitors.

I honestly don't know, normally that isn't supposed to work, unless the motherboard has new features that will allow that now.

Call or email asus and find out directly why you could do this once but not afterwords after repeated attempts.

i turned the multi monitor mode off and the second screen started working.
