So the first options to try would be, at least I recommend it that way, to
1) read out the EDID in Windows (if available)
2) look for matching EDIDs on the web
3) Use tools like the phoenix EDID editor (or similar) to create an EDID
The only option you would need then is
Option "CustomEDID" "string"
where "string" should be replaced with a full path to the file (e.g. "/home/myuser/myedid.bin"
The other way round you want to take a look at the options to disable the EDID or parts of it, and then either modelines or options like the HorizSync and VertRefresh etc.
I am in touch with the manufacturer (Edge10) of the screen, so I have asked if they can send me the correct EDID file. I'll let you know how it works, if and when I get it.
