I actually don't even know what to google. I have two monitors, NEC PA272 and Apple LED Display. The NEC is primary (center) and Apple is secondary (on the side). Both plugged into the DP outputs of the XFX RX 580 4GB (reflashed as Sapphire with the same config and timings). Apple uses DP to miniDP-female convertor, which is just a bunch of wires.
If I plug NEC into the topmost DP and Apple into the next (middle) DP Apple doesn't come to life. System doesn't see it, it doesn't even blink, for all practical purposes it doesn't exist. NEC works as a primary.
If I swap them: Apple goes into the first DP and NEC into the second I have a dual monitor configuration as I wanted but the roles are swapped, Apple becomes primary and NEC secondary. I get BIOS on Apple, OpenCore boot menu on Apple, etc. Not that it's a big deal, in MacOS I still have them the way I like it, but the fact that it doesn't work as I intend it to work bothers me. Also, I just can not understand WHY? DP outputs work. Cables work. Monitors work. What doesn't work?!?
P.S. Catalina 10.15.7
Any ideas please.
