Advertisements Whether de-interlacing is hard to achieve or not, an LCD screen must do this in order to display an interlaced source. In other words, when you feed your TV 1080i, it must de-interlace in order to display that signal on your 1080p panel. So the only question is whether your TV or your TiVo convert from other resolutions to 1080p better. In the three setups I currently have running on different models of TV that are all 1080p, I can see no visual improvement by running native and letting the TV convert the signal on its own vs. setting the TiVo to 1080i and letting the TV de-interlace that to 1080p. On other equipment this may not be the case. But if you can't tell the difference, then why go through the pain of having the screen constantly blank out when it switches resolutions?
