To protect the monitor, the HDMI firewall only forwards the signal lines used for audio/video data transfer (D0, D1, D2, CK).
To protect the monitor, the HDMI firewall only forwards the signal lines used for audio/video (A/V) data transfer (D0, D1, D2, CK).
All other signal lines are unconnected (CEC, SDA, SCL, utility/HEAC+, HPD).
This will block all non A/V interfaces (e.g. DDC, HPD, CEC, HEAC, MHL)
The SDA/SCL lines used for the DDC interface to provide the EDID information to the device are connected to an EEPROM on the firewall.
This is where you need to copy the monitor information to.
This limits the DDC interface to the EDID information.
