Monitor not recognising PI booting at same time

(1/1)

wirelessjava2002:
My monitor and Raspberry PI are booting at the same time, from the same mains power inlet into the cabinet. (Old VGA monitor using an HDMI to VGA adapter) However the monitor doesn't display the PI
(Re-Booting the Pi after the monitor has power works fine)

Does anyone know of an elegant way to delay the Pi until the monitor has power? (Or other solution to display PI from single AC power source/switch)

I have searched the forum but didn't come up with anything.

Thanks in advance.

Thank you, this looks as if it could do the trick.

This worked fine in my case (no hardware needed): add (or uncomment) hdmi_force_hotplug=1 in /boot/config.txt.

I had the same problem.   You have to change the boot config.txt.  this shows you how to change it.

You can set a boot delay so the pi boots a certain number of seconds after plugged in (which let's the converter and monitor be running when the pi is booting so it can be detected).

In the config.txt add the line boot_delay=3
