Corrrect. With no edid it will output 640x480@60 which is mandatory for HDMI, so you should always get an image (unless there is a hardware issue with the display, the cable or the Pi).I am under the impression that even without any EDID a 4B booted without storage medium inserted will display the diagnostic screen using a default resolution that any HDMI display should be able to accept.
