MacBook Pro M1 Connectivity Issues with Dell U3219Q Display

I recently bought a MacBook Pro M1 and using it with Dell U3219Q display. But If I boot the Macbook, the display can't find the connection signal, and it's closing itself automatically. For using display, I have to remove the USB-C from a port to plug in another port.

I'm using macOS Big Sur 11.3.1 on the new Mac

It's weird; because I was using the same display with MacBook Pro 2017 model without any issue.

What's wrong with the new MacBook Pro M1 models?

Solution 1:

The issue fixed by upgrading the firmware of the display to latest one. Dell released the firmware update app for the macOS and you can download it from their support page.
