Gauntlet Legends Monitor doesnt Sync

[lastyle]

Hi all,

i bought a Gauntlet Legends Arcade Cabinet with Wells Gardner crt (which works fine with the original Gauntlet circuit Board) but as i want to connect a PC with Hyperspin to the Cabinet i bought and Installed:

ArcadeVGA500 and Jpac (tried Jpac with all possible Jumper setting)

Drivers are installed properly but i cant get the Monitor working properly and Displaying a clean Picture. I can see that there is something but the Pic is scrambled and it seems there are 3 Screens on one. Thy Sync Led on the jpc is on which makes me think there is a relieable Video Signal at the Jamma connecotr.

No available resolution seems to work with the supplied Resolution change tool.

I also tried crt_emudriver and have the same result.

Trisync has been setup for 15-31 khz and Sandart crt for testing.

I currently dont have any Idea what to check and or change in my Config to get this Babe running fine.

anybody with a suggestion ?

Thanks in Advance....

that would have been a medium resolution monitor

that would have been a medium resolution monitor

yep it is a med res . do i need to connect that different ? or use different drivers `?

meanwhile i read that somebody here at this forum was struggling with nearly the same problem and solved it by switching the monitor to 15 khz.
sadly my main circuit doesnt match this solution.
