Ahem.  EDID version 1.4 exists too, in fact it's the current version.
EDID 1.5+ doesn't exist, but it should be backward compatible when it does.

I'm doing a lot of work on another EDID parser, including full DMT and
CEA-861 mode tables, monitor hotplug, all quirks from Xorg and the
kernel, EDID 1.4 support w/ CVT calculation, etc. right now for an
embedded Linux video project.  Would there be any interest
incorporating parts of that work?
