I got my xrgb-3 a few days ago, been fooling with it. One problem I can't seem to get rid of is this continuous ripple effect that shows up pretty badly in non-3D games any time you have a lot of one color. It's always there, just you can see it better when the circumstances are right. I managed to get rid of it on my xbox by forcing my xbox to display in 520p all the time, in this case it looks as good as any system with native VGA.
Can anyone give me any hints as to what needs to be adjusted to get a nice smooth picture out of this thing?
