DVI-D cape doesn't initialize with monitor plugged in

Some monitors have their EDID EEPROM responding to all addresses, including the one on the cape. You may have one of those monitors. A solution would be removing the I2C2 voltage translator U3 to disconnect the monitor’s EDID EEPROM. Only do this if you don’t want to use your monitor’s EDID.


Thanks. This was indeed the problem.
