Well, that doesn't make much sense, the pass-through is supposed to be just a pass through after all. Then again it added Jailbars to my image so must do something.Standard VGA mode on my HDTV looks whack yo. Blurry image with very slightly dark, wide lines going up and down the screen. It's just barely passable. But when I connect it through the XRGB-3's bypass it gives me a sharper picture.
Incidentally, if you've modded your Dreamcast VGA box it might be sensible to pass the DC through the XRGB3, in B1 the standard VGA should simply be passed through, where 15khz will be upscaled of course, though I've not tried this to confirm.
The SLG just adds scanlines, doesn't do anything else to the signal. The reason a lot of games don't work is due to the weird sync the XRGB3 puts out. Adding an Extron RGB interface helps in some circumstances, but if you're an NTSC gamer you really should be looking to the Frame Meister.Dammit. Looks like I got wrong information then. We had reason to believe the reason why a lot of the games didn't work was it had something to do with the voltage.
