did you even put the edid to the correct location?

Quote:yes, although the method of obtaining the edid can be a little different if you have intel gfx. At least on my intel systems /sys/class/drm/card0-HDMI-A-1/edid is always empty. In that case, you can get the edid from
Code:xrandr -q --verbose

I guess it could be partial or invalid maybe. But I think you would see warnings or errors in the dmesg if so. If you post it somewhere I can verify that it's valid.
Like I said before, add drm.debug=14 to the grub cmdline and dmesg |pastebinit. That will give a lot more info.

cat /sys/class/drm/card0-HDMI-A-1/enabled
xrandr --output HDMI1 --off
xrandr --output HDMI1 --auto
