Making a composit splitter

[ZAPPER]

Any techies out there? Here is the deal. I have 9 DOT-X TV video monitors (7 on hand and 2 on loan) and want to make a video wall of sorts. I have posted on this a time back But have not found a suitable (cheap enough) solution yet. Can I build a device that will split a composite cable into 9 outputs? I mean split it so as each of the outputs is 1/9th of the picture and arranged in a 3X3 grid. Could someone give the details and a list of parts. But wait there's more! The back of the monitors have several input output options. A regular coax, a coax looking type with twist lock lugs on the sides and a RCA type. The only one that I can get to work is the RCA. They were set up at the place I got them from with the twist lock connection but I wasn't allowed the guts of the system. I made a cable with a regular coax on one end and a twist lock on the other and it doesn't work. Maybe it's for differnt signal?. I took the back off the set thinking that there might be a jumper setting and there was. I moved the jumper to all possible options and a text box on the screen changes wording but I still can only get the RCA jack to work. Just wondering if I needed to use maybe 2 jumpers or somthing? Anyhow I have put off contacting DOT-X because I suspect that they are more into selling systems than wasting their time with a non-custermer. Iv'e done a half hearted search on the subject and found that multi monitor systems ain't cheap and or don't meet my wants. I also read that multi graphic cards can be buggy as hell. Any ideas or links will be great! Thanks

Not in the way you are explaining.
Must be done "internally" ie in a dedicated 'box' (the electronic magic of which eludes me) and have each monitor fed its respective signal. Think PIP (picture in picture) 9 times.

The Matrox Parhelia offers 3 outputs. 3 of them will make a 3*3 video wall.
(assuming your TV monitors will accept their inputs.)

I know what a paragraph is I just don't how to make one.(product of public education and that was 20 years ago)
Does BNC indicate a differnt type of signal? Or is there some reason that my home made cable dosen't work?

I can't afford to even look at the Matrox site!(If I were to build a ground up computer I do like their card/software bundle)

Thanks for your reply.

i believe the bnc connection has a signal wire, and a ground wire. i may be wrong though
