    Assuming one is using compatible monitors (like Dell U2515H) that support daisy chaining via DisplayPort, can an Early 2011 15" MacBook Pro drive two displays in a daisy chain?

    What I'm thinking is:
    MBP -> mDP-DP-cable -> 1st compatible monitor -> DP-mDP-cable (or just DP-DP) -> 2nd compatible monitor.

    I know it can drive two Apple Thunderbolt Displays in a daisy chain, and they are the same resolution as the Dell above, but I'm not sure if the same is true of DisplayPort monitors.

    I tried to do that (Eizo + Dell). Only got a mirror monitors (with lid closed). I couldn't get anything else.

    - That's too bad. It's probably due to the too old DisplayPort standard in the MBP not supporting MST.

    Incidentally, do you know which DP version is implemented in the Thunderbolt 1 output?

    thunderbolt doesn't support daisy chaining over displayport for some reason.

    - Not even on newer Macs with DisplayPort 1.2 support like the Retina MacBook Pros?

    That's exactly what I am seeing right now on my monitors. Has there been any progress on this?
    I am using the latest macOS Sierra version, like 10.12.3.

    Newer Macs all support DP 1.2. You can prove this by booting into Windows using bootcamp, which is working fine. Only macOS is showing this weird mirrored second/third screen :(
