I found that the /proc ELD files correctly report monitor_present and eld_valid when we hot unplug a monitor, but the other fields in the ELD file are not cleared out to their default state. As best I can tell, this is an ALSA driver issue, since our display driver only fills in the other fields when ELDV==1. -- nvpublic
