Some Additional Notes
Some additional notes on my Studio Display post I posted earlier today:
I baffles me as to why Apple chose to use two DisplayPort 1.2 streams instead of a single DisplayPort 1.4 stream on supported Thunderbolt 3 controllers.
My MacBook Pro 14” will use a single DP 1.4 stream, but my Hackintosh will use two DP 1.2 streams. The Intel JHL7540 does support DP1.4 streams but the Studio Display will instead choose to complete the handshake using two DP1.2 steams.
