    So let me explain what I am wanting to do.
    I have been doing a lot of reading on the internet and have a few ideas, not sure if they will work
    I am wanting to get my wii onto my 19" viewsonic VP191b au.viewsonic.com/support/manuals/download.php?id=68 for specs on monitor


    Now the vp191b only accepts 30+ kHz on the RGB and as I understand the PAL wii outputs RGB in 15khz. I am wanting to boost this 15khz to 30khz so my monitor will be able to display the image. Now there are a few ways of doing this I assume.
    I will be using the composite sync on the SCART cable diagramhttp://members.optusnet.com.au/eviltim/gamescart/gamescart.htm since my monitor accepts c sync
    I am looking to spend very little for this mod I don't want to buy a scan doubler for this. Is there any circuit that I can make to increase the kHz on wii. I found this for the n64 that I assume does what I am wanting but on the n64.

    Can I use the same concept to allow a higher kHz on the wii? Which will allow me to display the image to my monitor.

    I have made a cable that is component to VGA (hd-15) when I hook it up I get a picture but all in green....I assume its becasue the monitor is in Sync on Green. So I am trying to get my wii to output the RGB to my monitor. Any help on this would be greatly appreciated...

    I am wanting to make a new cable that is wii SCART to VGA using these pins.

    wii pins VGA pins hd-15

    7 -------> 1
    9 ------------> 2
    11----------------> 3
    5----------------> 5
    6------------------> 6 and 7
    12------------------> 8
    5----------------> 10
    3-----------------> 13

    I will then add my (hopefully do-able) RGB kHz amp/booster to pins 1,2,3 on my VGA connector. I assume I will have to pull 5v out of the cable to power it.

    I also found some info on a Japanese RGB amp circuit on the net..and I can't find the circuit diagram now...not sure if this would help my situation.

    Some sites I used for information

    Anyone that can give me a hand figuring this out would just make my day....and probably someone else as well.

    Anyone

    Is there anyone out there with knowledge to make this type of circuit with an ICs. There has to be a way to boost this frequency a little bit. Someone please give me a hand here I just need the know-how.:(

    Thats not doing anything to the frequency (kHz) of the RGB signals. It is purely a single transistor RGB booster... that is it just amplifies the signal a small amount.

    have you even just tried plugging the Wii into the monitor to see what happens ?? does it produce a viewable pic ?


    cheers

    Yes I do understand that, now. I am wondering if there is a way to use sometype of IC and a few components to increase the 15khz to a little over 30khz with sometype of circuit I can make. I just need to knowhow.

    where did you get the idea that the Wii was 15kHz ? is that written in the manual or on the unit ?

    I read it on a website...I would give you the link right now, but it is down. Someone figured it out that it only outputs at this frequency. Just like all the older gaming systems..unlike the 360 that outputs at 31khz. I will search for another site that says it.

    Well what it boils down to is that only the PAL wii will output the RGB signal with a composite sync. However I will need a way to get this frequency higher than 15khz. I wish I had a multisync monitor to test and see if it will display on them at that frequency. I know that on the gamecube there was a hack to output it higher than 15khz with a DAC chip mod.
