I'm looking at building a desktop around the Ryzen APU (eg. Ryzen 5 2400g) for productivity use, and want to know if it will support my multi-monitor setup when paired with a motherboard like this one with 1 displayport and 1 HDMI output: GIGABYTE GA-AB350N-Gaming WIFI (rev. 1.0) AM4 AMD B350 SATA 6Gb/s USB 3.1 HDMI Mini ITX AMD Motherboard - Newegg.com
I would use a Displayport MST hub like this Amazon.com: Monoprice 2-Port DisplayPort 1.2 to DisplayPort Multi-Stream Transport (MST) Hub, DP to DP: Electronics. 2 of the monitors are 1080p and 1 is 1440p.
After scouring the internet I cannot find anyone who has tested MST support with a Ryzen APU. Hope this is the right place to ask!
