P2419HC, MacBook Pro, dual monitors

@coupdevill  Fyi in general it helps to specify the size of the MacBook Pro since the 13” and 15” models have different specs, but in this case even the 13” should be able to do this. You will however need to connect each display directly to the system. You cannot use a daisy chain cabling setup because macOS does not support DisplayPort MST, which is required to run a daisy chain. The hardware itself does, as demonstrated by the fact that daisy chaining from a Mac works while the Mac is running Windows via Boot Camp, so it’s an OS limitation. But if you have both displays connected directly, you should be able to see both displays in System Preferences and set them to Extend mode rather than Mirror/Duplicate. If that’s not what you’re seeing, then please be specific about exactly how you’ve got each display connected in terms of cables you’re using, inputs on the display, etc. The more information you provide about your setup, the more likely you’ll be able to get useful assistance.
