Using two displays to Mac Studio using UBC hub with 2 x HDMI

Is it possible to connect 2 displays (extended display mode NOT mirror) to Mac studio using a USB hub. I have Anker 343 in mind which has two HDMI ports and can connect to USB C port of my MAC. I tried previously with a basic hub model but could only see mirrored displays.

Mac Studio, macOS 13.0

Two large full-color high resolution displays requires more data than can be placed on one USB-C cable. The Mac Studio MAX USB-C ports are limited to only 10 G bits/sec, while one 4K display requires around 18 G bits/sec.


In order to support two displays on one output port on a Mac, the computer output port, the cable, and the first device (Dock or Display) must all be genuine ThunderBolt, which has twice as many data pathways as USB.

http://MacSales.com (OWC) is still the most-recommended supplier here, because they have good return policies and a lab full of Macs. They pride themselves on their service, so they do not sell stuff that is so "difficult" it needs a lot of hand-holding to get working.


OWC sells their own private-label SSD drives, which are pretty good and reasonably priced, and you know they will work in your Mac.


Look for the "My Upgrades" link on their main page, and it will lead you to parts that will work in your specific model Mac.


They offer two different genuine Thunderbolt Docks supporting up to two displays are shown on this page:

Most often posted as NOT working properly on a Mac: DELL Docks -- Trouble Prone, Unfriendly, and NOT working properly on a Mac. Most require Windows to work at all.
