I’m gonna post this here instead of PM, since it’s helpful to many.
The cable I listed above will not work well with most display since the monitor I tested on years ago (SONY GVM-2020*)* has ‘video amp’ and ‘sync-on-green’ buttons on the back panel which almost all monitors don’t have, allowing me to make it work. The cheapest and best route is to buy a ps2/ps3 RGB scart cable and a scart to vga adpter off of eBay because, the cable I was gonna give you produces a picture that’s too dark and blurry because it doesn’t have 220uf caps on the RGB lines and a sync stripper like a proper scart cable.
Proof that the scart to vga concept works are theses images I took today…
It’s a standard ps2 scart cable (plastic cover removed to help me figure out what line is what) and a female scart connector that I wired up to a vga connector (homemade scart to vga). The monitor is a Sony GDM FW900.
I’m also throwing a few of my consoles into my arcade cabinet.
