Am i right in thinking that if you pass a HD signal through a computer or a HD signal, or any other signals for that matter, that comes OUT of a computer will be de-interlaced? I have this thought that computers only display in whole screens non-interlaced, so what ever signals that come out of the computer will be effectively de-interlaced for you. That means, the picture quality will be dependent on what software you use to play your video. Reason i ask is this whole HD thing. About how the 1080 format is interlaced... does that mean if you get a HDTV card on the computer you'll output a better picture to the projektor than if you buy a set-top hdtv receiver which will output an interlaced picture and leave the projektor to de-interlace it for you. For the 720p format, it shouldnt matter cos the signal is prog scanned anyway, and presumed to be de-interlaced already.
