Retropie won't load after initial startup script

[tinkydink]

Hello. I am new to rasperry pi and retropie. I used the rasperry pi imager tool and selected Retropi 4.6 (retro pie 4) to move to my micro SD card. When I plug the card in the raspberry pi 4 (canakit with 32gb card), it shows a startup script for a minute or two, then goes black and retropie doesn't load at all. I tried with a PS classic and Xbox 360 controller plugged in.

Am I doing something wrong, is there an issue with my SD card? Any suggestions would be appreciated!

Can you try writing the image from retropie.org.uk/download instead of letting RPI imager downloading the image ?

I tried it with the etcher tool as well and getting the same issue. The retropie image will show for a second, then the screen goes black.

@tinkydink The problem may be the display doesn't get properly initialized - maybe your TV/Monitor doesn't switch to the proper resolution.
Try adding hdmi_safe=1 to the config.txt file on the SDcards' boot partition, then try again and see if you get an image.

Thanks! Seems like it was a monitor issue, but now it's working!

hdmi_safe will set the resolution to 640x480, if your monitor supports a higher resolution, you can set it by using hdmi_group=2 and hdmi_mode set to one of the values detailed in https://www.raspberrypi.org/documentation/configuration/config-txt/video.md. You'll probably have to add hdmi_ignore_edid=0xa5000080, my guess is that your monitor supplies a wrong EDID and the Pi tries to set the video resolution to an unsupported value.
