    Can somebody help me. I want to take a signal from the RGB SCART socket on the DVD and put it to the VGA input of a projector. Is it possible and if so how?

    So do I.........my previous projector had RGB in via scart which obviously worked great, but my new projector only has RGB in via 15pin HD connectors although the manual seems to indicate the socket is wired for RGB, I tried making up a lead but nothing came through, are there other connections to be made as well as the RGB and ground pins?

    Guys,

    The other pins required are for "sync". I'll see if I can find a drawing of the wiring configuration in the shop and post the answer here tomorrow.

    Hi Gordon, I looked at the wiring and guessed it may need a sync signal so tried the H sync, but still no joy. So I await your input with anticipation! LOL

    I just got to get that RGB working.........

    Thanks Gordon,
    I did get in touch with KEENE electronics last week and they reckon they have had many requests for this type of connector lead, and they are presently working on it. Seems odd that no one has come up with one before, maybe theres a catch? What ever, we will soon find out! LOL

    I got in touch with Keene last year and they said it wasn't possible because the rgb signal from the dvd player is interlaced.I told them I thought my projector could cope with it but they basicly told me I was wrong and would be wasting my money.

    "Seems odd that no one has come up with one before, maybe theres a catch?"

    The catch is probably that most (but not all) projectors with a 15 pin VGA input expect to see at least a line doubled 32kHz or VGA 640x480 signal via this socket. They may not recognise an ordinary 15kHz signal from your Sky box/DVD player.

    Some manufacturers clearly state the input frequency range of their VGA sockets e.g. 15~72kHz or 32~105kHz, some don't. So you are left with trial and error.

    Best of luck to all those trying.

    Regards

    pin6=red ground
    pin7=green ground
    pin8=blue gound

    pin13= Horiz Sync

    Hi Gordon,
    Thanks for that info, I had them all connected except pin 14 Vert Sync, I know I can get the Horiz Sync signal from the normal comp signal at pin 19 on the scart, but do I also use this as the Vert Sync source?
    As to the scanning rates all the manual tells me about the RGB input signal is Hor and Vert are at TTL level (positive/negative polarity)........

    Ok got it......the rates are

    V sync = max. 56-120 Hz
    H sync = max. 25-80 kHz

    I guess this means no video RGB input eh?

    The Sanyo PLV-30 has H Sync 15kHz to 80kHz and V Sync 50Hz to 100Hz - does this mean it will accept an RGB signal from a digibox? Has anyone tried it? If so where could I get a suitable cable from, or would I have to make one myself?
