need soft15khz help

Post by jonny5 »

ive got it working and displaying on the cabs monitor but no matter how much i adjust the vertical and horizontal hold i cant get it to stop vertically scrolling.....

i can get it to almost stop but it still scrolls upwards slowly

and the colors seem a bit off

the JPAC light says its got sync

any ideas?

its an old GeForce 5500fx in a 2.4 ghz dell pc of shit

it seems to support the resolutions and i can switch to them....but the scrolling and colors arent right

i can take pics or video if necessary....

Sounds like the monitor is only getting one sync. You need to find out if A) the jpac is combining Hor and Vert syncs for you or not, and B) if you are then wiring those syncs separately (or not) to the monitor out of the jpac. Most arcade monitors accept cync on the horizontal input, otherwise you'll need to hookup both hor and vert sync lines to the monitor.
