When running get-edid | parse-edid with i2c-dev module loaded, It doesn't read my monitor correctly. The EDID reads fine with Windows and xrandr.
IIRC, get-edid doesn't actually probe any i2c buses, it uses vm86 to do vbe calls to the vbios. vbe will only provide the edid for whatever monitor it happened to probe at boot and likely won't work correctly once a real driver is loaded. It's also not multi-head aware so if you have multiple monitors attached or are using a different display than what was available at boot it probably won't work.
This is not a driver bug. It's a limitation of get-edid.
Created attachment 185121 [details] get-edid | parse-edid output According to the read-edid website and the program output, get-edid uses the i2c bus.
get-edid calls into the BIOS directly to access the I2C bus and doesn't uses the driver. With a kernel driver this is pretty much deprecated and shouldn't be used any more. Use the one provided in sysfs instead, try: find /sys -name "edid"
