This command to store current EDID data to file:<\/p>\n

sudo \/opt\/vc\/bin\/tvservice -d \/boot\/edid.dat<\/code><\/p>\n

And add this line below to \/boot\/config.txt<\/code> to load the EDID data above on boot, ignore EDID data from monitor<\/p>\n

hdmi_edid_file=1<\/code><\/p>\n

so RPi will boot with mode and resolution correctly even when monitor is off (or slowly starting on), this is useful when power blackout, the monitor starting slowly and is not detected by RPi correctly and fallback to VGA resolution automatically<\/p>\n
