    nvm i just checked my cable. it was a rgb cable with a bunch of converters on it. only the rgb to dvi seems to fit and the dvi to hdmi isnt fitting for some reason. i thought it did :rolleyes:

    seems like you cant convert rgb to hdmi as rgb is analog and hdmi is digital. basically you cant convert with a cable >>. there is a way but its not really a viable option.

    time to edit my other post

    You can do HDMI to DVI, but not to RGB. It has to do with some kind of encoding of the HDMI signal.
    There are adaptors that will be able to do this, but will cost you a small fortune (over $100).

    This is due to HDCP compliancy. Both ends of the HDMI cable require a "handshake" to confirm a digital signal and connection. As RGB is analog, it won't work.

    Edit*

    HDMI-to-DVI will work fine as well as DVI is HDCP compliant.

    well you could always take the risk. its only 4 bucks. if it doesnt work its not a big financial loss. when i saw a hdmi to rgb converter cable there was a big black box in the middle of the cable

    something like this

    --------------------------|----------|
    HDMI Connection ---------| ----------|---------------RGB connection
    --------------------------|_________|


    its not the best illustration but thats the best i can do it :(

    that cable was around $100 too

    i don't understand how that could possibly work (the 4 dollar cable i mean). but by all means, give it a shot :D

    Basically it won't work... as it was statted by the AW rep, there's some compliance problem and you won't be able to output your HDMI into analog.

    The only solution I found (and I don't know if it works) is using a some kind of signal converter, that will authenticate your RGB device as an HDMI compliant one.

    " Why do I need a HDCP compliant display ?
    HDMI is a new standard that comes with hardware protection called HDCP.
    If your display doesn't have a HDMI input you won't be able to display 720p/1080p signal on it (from HDMI sources)
    Prior to exchange Data Video, HDMI source is exchanging keys with HDMI display.
    Both have a special HDCP chip embedded. If your display doesn't have it, even if it's technically able to display 720p or 1080p signal, it will display a BLACK SCREEN.
    On Playstation3 for example: 1080p mode is only available through HDMI output
    Read about the HDCP display's nightmare and find out if your display is affected."

    Anyway... have a look at this website and the "HDfury":

    Hope it helps.
