It looks like RPiOS on your SD-card can't handle your HDMI monitor well, the firmware in the Pi itself can. You might do something with 'EDID' or so but I have no experience with that.Update: I have done a lot of looking into some codes for the config.txt and added "hdmi_safe=1" under the [ALL] this has generated a square with rainbow after booting with SD card inserted then goes to what looks like a command prompt then turns to "no hdmi signal" again. After that I commented out the "disable_fw_kms_setup=1" or changing it to zero gives me the raspberry pie loading screen where you can see its loading through file names at the bottom then it continues to another command prompt like screen before again turning the "no hdmi signal". This is extremely frustrating because every install video I have seen is flash the sd card then plug it in and boot up without problems.
Or files on the SD-card (bootFAT) are wrong or corrupt. Or SD-card reader fails or you haven't flushed enough before take SD-card out after write or SD-card is shaky.
