So I had trashed a USB-C video cable at one point when I last had three monitors running, before a round of Bios updates. Now, I am trying to hook up the third monitor via the USB-C and, while I get video on all 3, the are all 2|1 mirrored 3 times. If I remove the USB-C cable the HDMI monitor and Mini-DP both work just fine as two independent monitors... Samsung LU28E510DS/ZA, They worked before...
