working in more than 1280*1024 under Dos (Developers)

Actually, no. EDID version 2.0 (with a 256 byte structure) had a very short lifespan. It was deprecated and replaced by version 1.3 (that's right, the version numbers went backwards for an "upgrade" -- that tells you something very unflattering about the standards process).

Version 1.3 allows for multiple 128-byte "extension blocks" in addition to the main 128-byte block, which allows for the same information provided in version 2.0 and more. My EDID program doesn't decode the extension blocks -- I've never had a monitor that reported extension blocks that I could use for testing (and I've never had a version 2.0 monitor, either). I think all modern monitors use version 1.3, if they're EDID-compatible at all.

There's also been talk for awhile of replacing EDID with something new, but AFAIK it hasn't actually happened yet.
