Pi4b Headless Boot

Hi I need to boot the Pi4b without a monitor connected. Using the std ROOL download this seems impossible as the system will not boot unless there is a connected HDMI montor. Presumably the system is stuck doing an EDID search for a monitor? Surely this is NOT the correct behaviour? … and has anyone got a workaround? thanks JB |

Oh yes it is!! It trips one of up every now and again.
There are other way, preset a mode in config/txt? I haven’t tried that recently. |

Running a headless Pi has been apain in the **** ever since the P1. Each time a new build comes out I have to fix it again. Perhaps somebody will fix it once and for allways in 5.30 |

I have the following in my headless Pi:
In !Boot the screen configuration is set to Flatron L1910B 1024×768 C16M (i.e. not to native) but with no HDMI monitor plugged in the HDMI system does not power up and the Pi does not hang on boot. For the headless Pi with an 800×480 touchscreen display I set 800×480 explicitly in config.txt |
