I use the DVI because I have 2 sources with DVI out. The lack of OSD on DVI really bugged me. So I went to the storeroom and got out an old unused TV, bought a $25 box which connected the 990 S-video out to the composite input of the TV and viola, I have a 13" color OSD. It's really cool because I can have the picture appear normally and I can see the menu. No switching required. It's overkill, but the TV was gathering dust anyway.
