UNSOLVED
U2419HC, daisy chain, cannot extend monitors?
Hoping someone here might be able to help with a solution I’ve driven myself nuts trying to get this to work.
2x U2419HC - CPU DP OUT -> Monitor 1 DP IN -> Monitor 1 DP OUT -> Monitor 2 DP IN.
Monitor 1 MST On. Monitor 2 MST Off.
Monitors are on and mirrored. When I go to Windows display settings, it only recognizes 1 monitor. There is no option to extend the monitors and I cannot find any solution on how to get windows to recognize the second monitor, or to extend the second monitor.
Please help. Thank you

Hello,
Sorry for the delay as we had a technical issue yesterday preventing me from my next reply.
Do you have the same issue if you use the Intel Graphics app instead of the Windows display manager?

@lllw That's the correct setup for a daisy chain, but the behavior you're seeing of mirrored output between displays and the source system only seeing one display is what happens when you've got a daisy chain cabling setup but something in the setup doesn't support DisplayPort MST, which is required for daisy chaining. This has a few potential causes:
So what are the details around your system or its GPU? It might not support MST.
