Adjust the Universal Video Converter (UVC)
The Universal Video Converter (UVC) is designed to work with most EGA and CGA arcade
monitors. When you power the cabinet up for the first time, you may need to adjust the
settings on the UVC board to match the monitor. To correctly set up the UVC, you must
know the resolution and Horizontal and Vertical Sync setup of the monitor.
Depending on your cabinet, the J7 video output of the UVC can be connected directly to the
video input on the monitor, or to J4 on the Jamma Conversion Board to route the signals
through the Jamma harness to the monitor.
