/vr/ - Retro Games

apple monitor anon here, I'm trying to make a scart to da15 adapter to connect consoles to this thing but I can't get any video from it. Looking at the manual it says it wants 4 volts on the sync signal; can someone confirm does that mean I'll have to boost all my console sync signals? I suppose that's why it took my h/v sync from my graphics card so well...
