You have it a bit backwards.  Unless you are REALLY into some form of authenticity, save yourself the trouble and use a PC monitor instead.  You can get a 21 or 22 inch flat screen CRT for nothing, and they work really well.  If you need something bigger just find a TV.  Really, you won't notice the difference, but they are much nicer than an Arcade monitor.  And get rid of the X-Arcade controls.....

Since the cab is JAMMA, I was presuming that he had controls from X-Arcade (e.g. parts), not a preassembled panel (which obviously won't interface with JAMMA).

As for arcade monitor vs PC or TV ... it really does make a difference.

Umgar:

I tried a new higher quality SVGA cable last night. This made a huge difference on picture quality, but unfortunately still experiencing the constant scroll of the screen. I can stop the roll by playing with the v-hold knob but it's very tough to get it in the right spot (sometimes I get it stopped but not in the right spot, the screen is chopped through the middle). I think tonight I am going to shoot a short video to show exactly how I have everything set up and what I'm experiencing.

Quite frustrated so far as with both the JPAC AND an ArcadeVGA card from Ultimarc I expected this would essentially be "plug and play" plus a little tweaking to get the image "just right." Instead it's completely unusable out of the box, and a lot with a lot of tweaking I can get it "almost playable." Not what I was expecting:-/

Make sure that the "sync" line (the white wire) coming from the jamma harness
is connected to either a "composite sync" pin, or both the "positive sync" and "negative sync" pins.

Yeah that sounds exactly like the problem I had with my monitor when I first got started. Turns out I failed to actually connect the v sync pin. And then when I did, I hooked it to the wrong pin. Felt a special kind of stupid when I realized my mistake.  So double check continuity on those sync pins!

I see one white wire coming off the monitor plug (the one that plugs into the monitor board). If I follow it all the way back to the JAMMA interface and compare to the pinout diagram here http://www.ultimarc.com/jpac2.html it is wired into "P" (composite sync)

Some background - I got this cabinet off of Craig's List and the guy had already purchased the X-arcade controls (a pre-assembled two-player setup like the one here:http://www.xgaming.com/store/arcade-joysticks-and-game-controllers/product/x-arcade-dual-joystick/ , not parts) because the original controls had been vandalized and he was planning on converting the cabinet to MAME but lost interest. So the x-arcade set sits where the original controls used to be. Since I'm doing a MAME cabinet I don't see what I would gain from custom controls over x-arcade... if I was building a new cab from scratch I would definitely go that route but I specifically chose this cabinet because it was an MKII cab which I have some nostalgia for. I know I don't get a trackball with this set but... meh.
