I edited the
/boot/config.txt file to adapt to my monitor settings:
# uncomment if you get no picture on HDMI for a default "safe" mode hdmi_safe=1
But when I reboot, the hdmi mode seems to be set back to
4 which is 640x480
How do I apply the change?
This is the output of
tvservice -d edid.dat edidparser edid.dat
