jpac+avga+polo25

[Talon]

Help . I have searched all day
I have connected my arcade vga +jpac to the polo25 arcade monitor. When the bios screen appears the picture is rock solid but when WinXP boots the picture is terrible (fuzzy and jumpy) I have tried loads of different resolutions. some of the lower resolution the picture is fine but way too big and the H and V controls do not make the screen any smaller. When i start Gameex with the Avga set to on ,the Gameex screen is the same but when i start any game the picture is fine.
The JPAC has the 15 and 31 jumpers on.
please help
kind regards

Ok...
Looks like i can not go any bigger the 640X288. Is this normal? Are there any ways to get round this

cheers
