How do I change pi4 settings with no screen

[KF0AWL]

This might be a stupi question but I picked up a pi4 couple weeks back and a figured I would use a vga monitor I had for the display. I bought a powered HDMI to VGA converter to go between a wireless keyboard and mouse to run it but my issue is I get a no signal from the monitor when plugged in. I know the monitor works as I check it as a second with my laptop and from what I found I need to change settings in my pi to match my monitor. But how do I do that without seeing what I'm doing?

Have you tried both HDMI ports on the Pi? And they both do not work.

Usaually youd run the raspi config to set the screen value but as pistar runs a cut back vers of pi os and given it is designed to run headless it isnt included in the image.

One thing you need to consider here: with the VGA adapter you're using, the Pi may not react to "hot-plugging" the monitor as the required signalling may not be there.

Have you tried wiring up the adapter/monitor to the Pi *before* powering up the Pi?
