    Witam.
    Mam problem z ww monitorem a mianowicie po podlaczeniu monitora przez dvi obraz nie jest wyswietlany podczas uruchamiania komputera(niewidac opcji bios i loga windows podczas wczytywnia).
    Monitor pokazuje obraz dopiero w momencie gdy pojawia sie obraz "zapraszamy" i dalej w systemie jest dobrze.
    Na analogu jest wszystko w porzadku.
    Gdy musze zmienic cos w biosie przelaczam z dvi na analog co jest troche klopotliwe.
    Jak rozwiazac ten problem?

    Spec od monitorów

    Na moje doświadczenie .straciłes:
    - wsad(lub jego czesc) w scalaku-pamieci odpowiadającym za info. DDC po wej.DVI
    http://en.wikipedia.org/wiki/Extended_display_identification_data
    - potrzebny jest (JIG) + wsad(dump)
    *stosują kod ASCII
    troche mozna poczytac na
    TUTAJ
    ....
    zostaje Serwis Samsunga

    *b.czesto spotykane w samsung 193P (model 193PS )
    model code DI1PSQAQ/EDC
    Type № GH11GS


    mozna sczytac na programatorze zawartosc scalaka > ten zazwyczaj najblizej złacza DVI , (pierwsze dwie strony- moga byc same zera > tj.własnie utracona zawartosc.. wczasniej były zapisane dane.........)

    lub

    moze byc zawartosc w procku gł. np. (PLCC44) bowiem imp.SDA i SCL ida ze złacza DVI na procek
    *jesli nie ma żadnych kosci pamieci typu np.24C16/ 08..

    tak wygląda przykładowy......
