I have one of the earlier 4k monitors and wondering if OS X support 4k @60hz with dual HDMI 1920x2160 in Dual Mode. Since apple broke DisplayPort MST in Catalina Im trying to get my Asus 4k display working with dual HDMI. The monitor has a Dual HDMI mode to achieve 4k 60HZ which works great in windows but shows up as 2 extended monitors in OS X, so I was wondering if anyone had any experience with a similar setup to chime in. I am using a thunderbolt 3(not usb c) dual HDMI adapter. Btw apple completely bungled this. Im on a $4500 MacBook Pro 16" i9.
