Upon further inspection I think I found a part number and some other info:
JS270104-2192 Sony-R JS Dual Scan Also seems to be a cable labeled "15k / 25k switchable connector"
does this help at all?
There is nothing else visible and I dont want to start messing with the boards as I know nothing about monitor safety.
I am assuming that it is set for medium res right now and that with my ArcadeVGA I am better off changing it to 15k?? Just very intimidated by the prospect of messing in that area.
