    Alvin Gold refers to four-wire RGB in his review of the Arcm AVR 300. I'm probably being very dense but what is this? What are its advantages?
    Thanks for any help.

    Im not totally sure, think some players/tvs use the fourth wire to sync the RGB on scarts.

    the good news is the arcam can handle it, should you need it.


    DL the manuel from acrams site, it explains it better

    The best quality picture signal carried via a scart socket is normally RGBcvS (RGB with sync on composite). The sync signal means that the connection uses 4 cables. The more common in the USA RGsB (sync on Green) is not compatable without hardware conversion.
    To do the RGBcvS video switching via the Arcam AVR-300 you need to get a scart to 4 phono lead such as This. Plug the RGB cables into the Component input and the Yellow sync cable into the composite input. Setup the receiver to use RGB switchin in the menu and then connect another lead to the component & composite outputs to the Scart input of your TV. AFAIK the Arcam receiver will not convert the RGBcvS input to component, but only do video switching outputting RGBcvS.

    The advantage of this is that you can use the receiver to do video switching of higher quality RGB scart STB's, rather than needing to use lower quality outputs such as S-Video, or worse, composite. If your TV does not have a component input then you can get the best possible connection of say DVD, Sky, Freeview etc without needing to swap cables around when changing sources as many/most TV's only have 1 RGB capable scart socket.

    Hi,

    Does anyone know if this method also supports auto widescreen switching from SKY digital?
