Ah yeah, you are probably right. I did see that one suggested as a dupe, but it was not an outright dupe, just a launchpad suggestion.
(I also got confused, since AFAIK the HDMI out on my Dell laptop is hardwired differently to the mini-DVI out. e.g. it can only mirror, not span. Of course, there's no reason why mine is not dissimilar to other laptops.)
