Product: HP Business Z27 4K monitor
Operating System: macOS 10.14 Mojave

My Z27 4K monitor does not work.

It receives power, it turns on/stand by/off (amber/white light on the front) but the screen stays blank.

When I plug my Mac, (I have tried with 2 different USB-C cables on my Mac Mini, and a Mini display to Display + HDMI with my MackBook Pro 2014) the front light changes from Amber to White and stays white (indicating it receive video signal), but the screen is black.

Pushing the screen buttons do not bring up any onscreen menu. It is like the LCD display is dead!

What should I do?
