I don't have a 1070 to test with, but it sounds like the 1070 behaves almost exactly the same as the 990 except for one difference. While the 990 will replace a component video input with a blue screen to display the OSD menu with a component input, the 1070 does not add any OSD data (either status info or the menu) to a component input. The s-video and composite video inputs would get both status info and menu superimposed on the input video signal, and those sources would then be converted to component video for the monitor output. That means that you should be able to use an s-video or composite video input (or a video input with nothing connected at all, such as the front input) to get the setup menu while using the component output.
