Setup is
Atari Vindicators with Sharp 19" display. Manual says pin 6 is "Negative Composite Sync"
http://www.arcade-museum.com/manuals-monitors/Atari%20Monitor%20TM-304%201st%20Printing%20Sharp%2019in%20Color%20Raster.pdfI have tried to connect an ArcadeVGA (2nd gen) to the arcade using the breakout cable / amp from Ultramarc. The video looks perfect from the botton to about the last 10% of the top. The top 10% of the screen is skewed to the right or sortof looks rolled over. I have tried all sorts of adjustments on the monitor with no luck. Am I connecting the syn wire correct to the vga amp? I connected the pin 6 wire from the monitor to the syn connection on the amp.
