there is a ps3 vga cable?
Its a wii/ps3 3rd party one that doesn't work with the wii! Basically converts component to vga so it very well could be an issue with the cable itself. I bought it on a whim expecting to use it for MGS4, decided against buying MGS4 last month, then bought MGS4 today
oh, i was hoping it's official.
btw does your monitor have dvi? why not try hdmi to dvi if so?
as for your question, no idea but try messing with your monitor settings.
