    That's not how component and VGA work at all. You'll need something like GCVideo to get VGA working on the Wii.

    @Shank said that gcvideo doesn't work with the wii.

    Nope, its not that it "doesnt work on the wii," it requires modification to work on the wii, and nobody stocks a wii ready board as of writing this post.

    on bitbuilt.net, @stitches said,"The firmware isn't Wii compatible yet. Even if you wired it correctly, I've seen mention here that it won't work."

    what modifications would you need to do to get gcvideo working on the wii

    The needed modifications are not public yet, but with basic skills of FPGAs anyone could do them

    Why wouldn't that work? The listing sounded like it was converting from YPbPr to RGBHV or at least RGBC, which are both useful for Dalian.

    It's just an adapter. It's only good for a device that accepts YPbPr through a VGA connector, which Dalian screens do not.

    Ah.

    Well, one *should* be able to convert them fairly easily with passive components and maybe op amps. Probably need some diodes in there too. But if one's asking then it's probably out of their scope.

    @Fiskers1208 Some screens that accept component use the same pins as vga, since they are electrical similar, and it reduces cost because they do not have to have 2 ports. A similar example would be how some modern tvs have composite and Y (of ypbpr) use the same plug. This adapter has no electrical components, and just connects the pins of Pr to R, Y to G, and Pb to B. Using this would be the same as soldering your component wires to a vga port.

    1: This is not the topic
    2: its specifically stated in the files I released, the ones you bugged me several times to release.
    3: I already told you that your laser wont work, and even fi it did, you need a sealed cutter because ABS emits small amounts of cyanide gas, which is dangerous unless your laser is sealed and has an exhaust system. You also probably need a CO2 laser so it doesn't burst into flames

    I highly recommend you or anyone else not trying to laser cut a case unless you are very experienced with a laser to begin with, especially ABS because of how hard it is to work with with a laser.

    The Dalian displays accept electrical signals that directly correlate to the level of red, green, and blue on the screen. YPbPr, used in component cables, is a separate standard: the Y wire has an electrical signal that correlates to a black and white signal. This is created by mixing approximately 30% of the red signal, 60% of the green signal, and 10% of the blue signal. The Pb wire has an electrical signal that correlates to how much brighter the blue signal should be than the Y signal. Pr is the same, with red. Using analog electric math, you can use these results to determine how strong red, green, and blue should be on the screen.

    This is from the early days of color TV. Composite carries the equivalent of Y, plus a low-resolution radio-encoded PbPr signal. This way, color TV broadcasts would play on monochromatic TVs, and they wouldn't need to reassign TV channels to account for additional bandwith for excessive color information. While Europe had SCART, America (and Japan, IIRC) never had standard ports for carrying RGB until the days of VGA, which is almost always used for 480p60 or higher resolutions. The best we got was component with YPbPr, which is theoretically just as good. For this reason, the Wii doesn't put out RGB on its own, only YPbPr.

    Thanks for the help. Is there a way to use VGA on the wii, other than GCVIDEO?
