One thing worth bearing in mind is that DVI is not hotplug safe (well officially neither is VGA) but hot-plugging DVI can cause all manner of funnies.
If DVI isn't hotplug safe, why does it have pins for hotplug detect? http://www.google.co.uk/search?q=dvi+hot+plug+detect
Maybe the interface has a specification that can include hotplug, but in my experience it either isn't implemented or is implemented in a broken way as I have seen/heard of several cases where hotplugging a DVI interface can cause rather strange issues including Monitors that think they should be asleep or stuck on the wrong input.
Also the connector assembly itself isn't hotplug safe IMO (except perhaps mini-dvi) as it is possible to plug it in a way that all pins don't connect at the same time...compared to connectors designed for hotplug like USB/Firewire/SATA etc
