The OSD menu produced for the 990's component output is a 480i signal that takes the place of the selected video source (assuming the video source is a component input). In most cases, that's not a problem - it's the same resolution produced by older interlaced DVD players, for example, as well as many PS2 games. Some displays, however, will only accept 480p, 720p, or 1080i. It's pretty rare.
