Has anyone got the dp passthrough to work on the ASUS proArt x670E Wifi mobo?

Ive been tearing my hair out the last week trying to get the passthrough to work. Anyone out there have success???

My specs are 3090 FE, 7950x3d. I bought this motherboard specifically for the display passthrough but can’t seem to get it working for the life of me.

I have my “dp-in” connected to my 3090FE and hooked my usbc monitor to the 1st thunderbolt slot and nothing.

Additional things i have already tried.

  • swapped multiple known working DP cables as the passthrough dp
  • tried all the dp ports on my 3090
  • tried a host of usbc and thunderbolt cables even going as far as borrowing a working thunderbolt4 apple cable to connect my monitor to the usb4 port

Bios settings i tried

  • disabling the igpu; enabling the igpu
  • setting hybrid mode on and off

The one thing i noticed if i have the igpu enabled i get the bios boot screen to load on the usbc screen but as soon as windows loads up the monitor disconnects. At this point I would even be happy to have this usbc monitor use the igpu while my mains use the 3090 but that doesnt seem to work either.
