Another problem I've come across recently with DDC is that I've got 2 
field systems running through a KVM to a single wide screen monitor. If 
the system not currently outputting to the active monitor gets rebooted, 
DDC picks up some weird settings from the KVM (which I assume is 
emulating a monitor somehow). The result is that the system has to be 
rebooted again while switched to the monitor. Disabling DDC here would 
really really help.
