    I am trying to connect my laptop to my Panasonic PW7 plasma component board,
    I can connect my laptop to my pw7 via VGA with no problems what so ever,
    The problem arises when i try to connect my laptop to the PW7 via a (VGA to component cable) ( i suspect it a RGB issue)

    I get a picture but the colours are contorted, Before you say i have the cables in the wrong holes, I dont because i put my xbox in and the picture is fine (which rules out the component card)
    I have tried with different cable just to rule them out.

    I have a picture to show what i mean, Top is plasma bottom is laptop.

    What i want to do is put the computer through a denon amp and have the capability to play stuff to the plasma or projector without switching wires.

    So what type of convertor would i need?

    Computer VGA > denon 1909 > plasma/projector

    Regards

    Do you have a RGBHV board or just Component/RGsB?

    Have you changed the component board setting to RGB in the menu?

    I used to use a JS Technologies converter but can't find it on their website any more. There are other good companies such as Gefen that offer such converters as well.

    The laptop is outputting RGBHV which is red, green, blue, horizontal sync, vertical sync.

    Component video is green, red and blue coloured cables but are not RGB, they are YPbPr which is a mathematically lossless conversion from RGB where the sync is going down the green coloured cable but it is not carrying just the green component of the image it is carrying the luminance portion.

    Your cable can only be used with a device which is using a D-Sub connector, to send something using component colourspace (such as the Xbox). Your laptop is in RGBHV colourpsace so is never going to work into your component board.

    That changed the colour a little for the better.

    So what do i need to get my computer to go through an amp and onto the projector/plasma,
    Would a change of graphics card with a different connections make any difference?

    A GFX card with HDMI or DVI-D or a transcoder

    I thought it was a laptop? Most cards can do both outputs.

    Sorry was testing on a laptop the VGA to Component lead to see if it would work ( if it worked on the laptop, it would work on the PC )
    It is a PC i am doing it for just that the laptop was handy to do the cable test and it failed.

    I have had to extend my screen to show on both (which is fine to be honest)
    I think i have this sussed now the way i want to go.

    GRaphics card with DVI/HDMI if the receiver has that, or a graphics card which can do component colourspace so that you can use your d-sub to 3 RCA cable.
