I'm trying to connect the old generation LG UltraFine 4k Display (USB-C DisplayPort) and the old generation LG UltraFine 5k Display (USB-C Thunderbolt) to a 13" MacBook Pro from 2019 (with 4 Thunderbolt 3 USB-C ports).
Here's what works:
- If I connect just the 5K display through its Thunderbolt USB-C cable, it works fine.
- If I connect just the 4K display through its DisplayPort USB-C cable, it works fine.
Here's what doesn't work:
- I can't seem to daisy-chain the 4K display of the 5K display as there's no incoming DisplayPort/Thunderbolt port on the 5K display.
- If I connect both displays to the MacBook using two different ports, it just registers and uses the one I plugged in first.
I suspect that the Mac somehow either can't handle or don't understand running both Thunderbolt and DisplayPort at the same time - but maybe it's a configuration issue? I haven't been able to find anything online about this.
