The 990's on-screen menu works with every input except DVI. The OSD "pop-up" (one or two lines of text reporting volume level or input) is overlayed on the source video only for composite and s-video. Component inputs do not get that OSD "pop-up," but they do get the setup menu (it is shown on a blue background, completely replacing the source video). Since the OSD is overlayed onto the composite or s-video sources before they are transcoded to component, the OSD still shows up for those inputs even if the output from the 990 is component.
