A method of configuring a display device interface (DDI) detects a trigger signal, generated by a display device. If the trigger signal is associated with a power on event, a full configuration of the DDI is performed, including loading display device capability information provided by the display device into DDI configuration registers and setting one or more DDI configuration parameters accordingly. If the trigger signal is associated with resume event, rather than a power on event, a modified fast link resume operation may be performed to route the trigger signal to a controller configured to explicitly write display device capability information to the appropriate DDI configuration registers before setting the corresponding DDI configuration parameter accordingly. The DDI may include a re-timer, between the DDI source and sink, configured to snoop the explicit write transaction such that the re-timer configuration is also updated.
