Hi
@CaseySJ My ID was originally 0300913E. I tried 07009B3E and 0300983E and neither one worked.
I have my machine starting up, but the Ultrafine 5K is seen on the thunderbolt bus, but not as a display (the audio on the monitor works). The Pro Display XDR does not show up on the TB3 bus at all. Any ideas of what else to try? I've also tried the Belkin displayport to thunderbolt VR cable. No luck. What is working is dual displayport to a 5K monitor with dual DisplayPort inputs. These are the boot-args I'm using: slide=0 alcid=7 darkwake=0 shikigva=80 agdpmod=pikera
Is there a BIOS option I should be setting to enable DisplayPort in to TB3?
Any ideas what to try next?
