Re: EDID, as I said, you need to look it up on the web. Extract it with tools/apps such as Monitor Asset Manager, then inject it by adding the following property to the graphics settings of your bootloader's config:
AAPL00,override-no-connect <XXXXXXXXX> DATA
where <XXXXXXXX> is your 20bytes (or so) EDID info in one long consecutive hexadecimal string. See the WhateverGreen user manual.
