ArcadeVGA Vertical Roll
« on: August 08, 2004, 06:47:35 pm »
I have just connected a JPAC and ArcadeVGA to my cab. The cab works perfectly with Jamma boards / MVS / CPS systems. With The PC connected through the JPAC and ArcadeVGA, I get constant vertical roll. It can't be stabilised with the V-Hold pot, and the screen also has the jitters.

Any idea what this could be?

Thx

I believe you need to combine both the H and V neg- sync's going from the vid card onto the monitor. had the same issue
