DisplayPort 1.2 support and daisy chain

[narbatucker]

I currently have my a display successfully daisychained to my U2515H with my RX580. Does anyone know if Startech's MST hub is likely to work in High Sierra 10.13.3 or 10.13.4?

Can confirm MST using High Sierra 10.13.6 with AMD R 280x on mDP to DP port on two Dell U2415H monitors. Hot swappable. However, it does exhibit a greater amount of issues such as screens not initialising on boot, screen artefacts waking from sleep etc. However the issues are infrequent and temporary with the worst solution being pulling MDP from graphics cards and reseating or turning first screen off and on again.

Certainly not consistent as a direct cable run to each monitor.

I just tried with my RX480 on osx 10.13.1.

Daisy chain works. Even worked as a hot plug. I daisy chained my two Dell U2414Hs, and got a mirrored display on the chained monitor. Remembered I'd disabled DP 1.2 a long time ago. Re-enabled it on the 'first' monitor and OSX then saw them both as separate displays.

This should make my cabling a bit less annoying!

Hi, i have two dell U2417H and RX580, i'm on 10.13.6, and i too get a mirrored image on them, even though MST is enabled. Also when i plug them both with DPs in GPU, both go black. Did you set something special in clover?
