well, i hooked it up to my tv via hdmi, and set it to 480i, still doesn't work. i would try to hook it up to another monitor... but the other monitors in my house aren't widescreen, and i heard it only works with widescreen... or i wonder if they meant that you should only use widescreen or else the stretch would be terrible.. maybe it still displays though
EDIT: so i tried hooking my ps3 to the other 2 monitors in the house, one of them had the same problem as my widescreen monitor; detected a signal, but had a lit up but black screen. the other monitor didn't detect a signal
