U2720Q, MacBook Pro (13" 2020) USB-C issues

I'm desperately trying to connect my new 13" MacBook Pro to my display.

The cable/wiring seems to be working, as

- macBook is being charged, and 

- Error: no signal via usb-c appears on display.

I've tried everything from unplugging, new usb-c cable to software and firmware updates. 

I need HELP
