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.

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? Do you have any solution for this issue?

Thanks.

PS: I'm using macOS Big Sur 11.3.1
