Pi4 does not output HDMI signal

Hi. My Pi4 still does not output anything from the HDMI port. Luckily I have a Pi 3B+, and the edid file is:

edidparser exited with code 0
And the screen works on my Pi 3B+, any advice?

Oh and of course I have copied the edid file works on Pi 3B+ to the Pi4 and forced the Pi 4 to use the edid file.
Still nothing

And... tried on another monitor(which is not mine), it works and displays well. However, I was warned not to collect any information from that, so...
