Hello,
I'm still on it.
We don't usually have that, because EDID is not only about mode (resolutions @ refresh rate) but also
detailed timings.
Default timings and what to fall back on tends to standard defined. Being even slightly off a desired timing is enough for the display not to synch properly or stay blank.
We might be able to give you a way to add a mode, but not timings, so that may or may not work depending on what the monitor timings are.
Kind regards,
Alban
