The Apple specs page for the M2 Ultra says that machine supports 8 outputs, but the Millumin recommendation page only lists 5 outputs. Guidance appreciated..
Yes, it can. We updated our help center accordingly (as this recent M2 Ultra chip was not mentionned before).
Please note that Millumin is not managing displays : this is macOS that is doing so from System Settings. Thus, the more displays are detected by macOS, the more displays Millumin can use.
In brief : Millumin always follows hardware limitations (no software limitation).
