Hi downloaded and installed this image on my PI 4 LibreELEC-RPi4.arm-9.95.4.img.gz
Booting from USB, I placed the edid.dat file (one that I always used in the passed) on the USB root and added the hdmi_edid_file=1 to config.txt
But it is not giving me the correct choice of resolutions, if my AV amp or TV is on then it does, so it looks like its not reading the local file.
