M1 Macbook pro 14" external display problem

Hi,

I have a problem with the new 14" MacBook's.

I had two use two external monitor plus the internal monitor as well at the same time, and somehow the USB C to HDMI output was dropping after a few minutes.

This was happening in 8 different macs, also I tried different adapters too... didn't helped.

Soon as I unplugged and plugged back the adapter it fixed the issue.....

But the machines was used for a show.... so I need to find a solution before the next show.

Did someone had similar issues with the new Macs?
