Help - Unable To Extend 2 USB monitors

[pdubhu10]

Hello,

I am running on a Mac Book Pro 2017, trying to extend to 2 HP Elite Display via USB C adaptors. Only one monitor extends, the other monitor is stuck in clone mode and not even recognized in the display settings. Any suggestions? I'm running on High Sierra using DL driver 4.3.1 .

High Sierra > 10.13.4?

If so, you can't. The drivers are all borked after Apple changed something and the only workarounds are hacky airplay-esque drivers.
