Nothing, theres no HDMI output at all but the moniter itself works fine.What do you get on the screen if you boot up with no SD card and just power supply and HDMI connected?
If challenged for confirmation, my experience is that Raspberry Pi Engineers will say that given a reliable Power Supply and a working HDMI connection the absence of the Boot diagnostics display ( see - https://www.raspberrypi.com/documentati ... iagnostics) indicates a dead/failed/faulty RPi4 board.
