Apple Thunderbolt Monitor & MacBook Pro M1

Hi,

I picked up some threads with the same problem, I have never seen an official answer.

I use an apple Thunderbolt Monitor 27 with Macbook pro M1. It worked for a while with an adapter and then it stopped working (tried everything rebooting, change refresh rate). When I plug the monitor to an old Intel Macbook pro 13, it works just fine.

At the meantime I used a HDMI and it works just fine. One day the macbook screen started acting bizarre, it turns on and off. After rebooting it started working again until one day it went black. I took it to an apple store and they changed the display (thanks god had applecare).

Here is the interesting part, after fixing the display issue, the thunderbolt monitor started working again for about a month and this morning it stopped again.

I am wondering if a logic board goes bad or something and that causes this issue.

Any help is highly appreciated.

Thanks
