    Trying to pre wire for front projection. The Optoma H76 finally shipping I think, Will get projector for 5 to 6 months anyway so maybe it will be easier to get by then.
    Can't find a picutre of the inputs that would help.

    The Projector states the

    Inputs are:
    DVI
    BNC
    YcbCr/YpbPr
    RCA- type jack
    S-Video
    dual IR receivers

    Outputs are:
    Dual +12V relay
    RS-232

    I know I need one DVI

    I know I need one S-Video

    These are the one's I have questions about:

    BNC ? What would this be for?

    YcbCr/YpbPr --I think this is One componet cable right?

    RCA - Type Jack -- dont know what this is for- do I need one composite cable for this?

    Outputs

    I assume the dual ir receivers are to relocate the ir pickup for the projector can't figure out why there are two lol?

    RS-232 ? I have no idea what this is


    If anyone could give me a hand it would be greatly appreciated

    What sources will be input to the projector?
    DVD, VCR, Cable/Sat.......

    Does your DVD player have DVI out, component out? You may not need to run S-video if your other sources have component outputs (unless you run out of inputs on your projector).

    YcbCr/YpbPr is the component input.

    There 'may' be 3 x BNC connectors for component input, however, I am not familiar with the unit you refer to so it/they may be for something else.

    BNC is a insert/twist/lock type connector (useful in a situation like a remotely mounted projector where you don't want to worry about a cable coming loose).

    Here is a component cable with RCA to BNC:

    Hey paul thanks for the reply

    I feel kind of stupid, I finally found optoma's web site and got to look at a pic of the connections.

    I also did more research and figured out all the lingo I think lol
    The BNC connections are for r,y,b,vsync,hsync

    do you know anything about bluejean cables?
    any good ? much cheaper than cobalt cable or cables to go.

    is there really any big difference in these companys cables?

    Thanks again

    I don't have experience with bluejeans, but they seem to have a good reputation on this forum.

    I'm not a believer in high end cables (and their costs) but would spend more of my money on a good quality video cable (I have not been able to tell the difference in audio cables or speaker wire for that matter).

    Some other cable builders would be:

    One more quick question please. And I think I will be all set LOL


    DVI Cables?

    Projector says DVI-I (HDCP)

    Most of the cables I have found are DVI-D and some are DVI-I

    What is the difference? Will DVI-D work for me?

    Thanks again for putting up with a Noobie

    Many longer DVI cables have not been ranked all that "great". IMO, the real benefit to DVI is copy protection. So, it's more a studio connection than a pure improvement. Not having DVI experience myself, I can't say there are never gains. Perhaps they are. But the reality of it is, component video is pretty darn good. I have 2 displays with DVI and one output device, and really, no desire to use them.

    As far as the 5 connector BNC, you will likely only want that if you use a scaler/line doubler. Not being familiar with your projector, I don't know if it's digital, LCD, or CRT. CRT stands to benefit the most from the 5 coax BNC connection using the external doubler. Most of the newer digital/LCD are HDTV grade already, no doubling required. I don't personally know of a DVD player using the 5 coax setup. But I suppose it's possible they exist. But if you were to need one, I have a 5 coax bundle on hand that would be really sweet for them with pro-BNC connectors. One HTF member purchased one already, and he positively loved it.
