MacBook Pro (M1, 2020, Big Sur) set up dual monitor

Hi Team,


Previously, I was using the 2017 MacBook with Catalina OS and connecting two HDMI in my USB-C to Dual HDMI as it worked perfectly as my second screen and not as mirrored (they are separated).


However, I have a new laptop and want to use the same dual monitors, but they will work as mirror monitors rather than separately. I tried to look at other similar cases on the apple-thread and how to recognize and split the monitor, but none of them worked (for my case).


Could you please check and see what I need to do in order to get the dual monitor (not mirrored)?

Fyi, am using this Hub :https://24h.pchome.com.tw/prod/DCADM1-A9009N8EF


Thanks a lot!

MacBook Pro 13″, macOS 11.6
