    Am I wasting my time? I bought a suitable cable to connect my panny DVD player, which has component out, to the VGA socket on the TV.

    I get a nice sharp picture alright but there are problems. The colour is all wrong. The basics seem to be there. If I remove and replace the colours in turn I can see each colour contributes to the overall colour. It's just all wrong with basically a green tint to it.

    I can provide a picture if you think it may help. Hopefully you will just saymit will never work or it needs so and so to work!

    What's your thoughts?

    I just changed my old vga box to a VD-Z3 and after some fiddling get a perfect picture. Im using progressive scan on a PAL dvd of Enterprise as i type this and it looks fantastic.

    I think there may be some issues with using a cable for this instead as you can't adjust the settings. Where as vga boxes have a bank of dip switches to adjust the settings to be suitable. As you have a green tint it could be caused by using a straight cable rather then electronics. Considering the difference I have found between using "generic" component-->>vga box and a "branded" one, I'm not sure a cable alone is suitable enough for this screen.

    :oops:

    I dismissed it in the past because I thought it was a games adapter :confused:

    I've now done a search and I see it's much more than that!

    Where's the cheapest place to get one?

    (sorry if you've already told me in a previous thread!)

    Thanks

    Dave

    @DaveP, the reason for the green tint is that YUV component to VGA cables connect the signal as follows: Y->G, Pb->B, Pr->R (based on the Toshiba xxWL56 manual). The Y signal is the luminance (or brightness, without any colour information), which is being (mis)interpreted by the TV as green instead. It seems the TV can do sync-on-green on the VGA input, not all VGA monitors can do that, so you get a picture but the colours are wrong.

    The separate box converts the YUV colour space into RGB. A TV that can really do component over VGA will perform the same function internally (the Toshiba has a separate YUV mode when cycling through the inputs).
