Disconnect all the wire on the DC VGA cable leaving only:
R/G/B/H/V and ground.
Do you ground all of them? Which one do I ground?
Do I need a Chip in order for this to work (LM1881)?

I have no idea what you are asking here? The only wire you snip in the VGAbox av cable is the one that leads to the 31khz pin. You do not need an LM1881.

I replied to you in the gamesx forum (maybe you didn't see). I didn't know you asked it again here. Post again if you are still having problems.

Ok, I've cut the 31khz wire (leading to pin 6) and I have a computer VGA cable ready.
My question is:
It seems I am getting out of the VGA box:
R, G, B, horizontal sync, and vertical sync (and ground).
BUT - the arcade monitor is accepting R, G, B, composite sync, and ground.
Is on of the wires coming from the VGA cable composite sync?
or Do I twist vertical and horizontal sync together to get composite sync?
Please make it clear - I'm a newbie.
and thanks for helping us newbies out.

If you're using a J-Pac, just plug the vga cable into it.
If you're not using a J-Pac then twist H and V sync together, just like if you were doing a PC to arcade monitor.

YES!
I have successfully hooked up my dreamcast to my arcade monitor!
Thanks to everyone who posted with all your good information.
Now on to the very tedious task of wiring in the controls....
