Hi, this is my first post in the new forum

I just installed my new JPAC into my CAB, Im using an HANTAREX MTC9000 21" arcade monitor and a CREATIVE GEFORCE DDR (Annhilator PRO).
When I use the cab with my game-boards the image is perfect but when I connect it with my PC, using the Fraggals CD and ARCADEOS, the image quality and color is very good, but the image blinks 1 time per second more or less.
I cant fix it adjusting monitor options, the image dont roll but the blinking problem is dissapointing me

If anyone can help me with this problem... I can try anything
