I am looking at using a honda oddyssey lcd navigation screen that has a red, green, and blue signal but has a single horizontal/vertical sync signal.· Any ideas on which driver it would use and how to set it·up?·

    There are some nice suggestions in this comprehensiv article www.tkk.fi/Misc/Electronics/faq/vga2rgb/interfacing.html how to electrically "add" the sync signals; however there exist different kinds of combined sync signals, including inverted ones....


    Edit: I just had a look into some VGA drivers... they set the sync signals explicitely. There is no "configuration" but you could easily modify their HSYNV/VSYNC/BLANK routine - when you have some idea how exactly your combined sync signal shall look like.
