Do you have any suggested resources I can use to research this?

I’d love to be able to build a dongle for people that supports 4K/120 HDR without needing anything else.

I’ve ordered a CAT24C208 EEPROM which supports segment pointers so it should support 512 byte EDID.

However it sounds like I need to figure out to trick the source into allowing higher pixel clocks…
