Unable to get 27" TB display work with M1 MacBook Pro through adaptor

[lovecd]

Tried to use my 27" thunderbolt display with my M1 macbook pro, but has the following issue, what could it be wrong here?


1. No image shows up when connecting with my 16" Macbook pro through TB3 to TB2 connector (connector has been tested in good working condition with another TB display I have).

2. Image does show correctly if connecting with my 2014 21.5" iMac desktop, but webcam, speakers and 3 usb ports at the back are not detected at all.

Is this due to malfunction or defect at all-in-one cable or logic board from this display? Any thoughts?

Thanks,

It normally pop up a notification window if it detects any devices connected, but I didn't see anything showing up, so, must be something else.
