    Hi all,

    i have an NEC VT-440 Projector and want to make my own component->vga adaptor.
    The adaptor will have 3 female rca plugs at one end ( to connect from dvd,xbox,ps2,gc) and the vga connector at the othe end which plugs into the projector.

    looking at the pinout of the HD-15(VGA) connector:
    Pin 1 is Red Video
    Pin 6 is Red Ground
    Pin 2 is Green Video
    Pin 7 is Green Ground
    Pin 3 is Blue Video
    Pin 8 is Blue Ground

    is it just a simple case of soldering the rca plugs to relevent pins, or am i missing something, do i need to use any of the other pins in the VGA connector e.g sync or other ground?

    cheers

    If the PJ can take YUV type component video on it's VGA port, then I think the above should be OK (from a component video ouput on the back of a DVD player, you've nothing else you can connect anyway :) )
    Composite sync is embedded in the Green (Y) signal for component video.

    If the PJ can take this signal, then there will no doubt be a menu setting to set the VGA port for component (YUV/YPbPr etc) input!

    Brilliant :clap:
    yes the PJ can take component video on it's vga port, the manual recommends connecting a dvd player this way (i.e YUV to VGA), and there is an option to select RGB or Component.

    cheers
