Dreamcast flickering on BVM 2011p

[Docktor J]

Hello all, lurking on this forum inspired me to get a Sony BVM 2011p which I'm chuffed with. Megadrive and Saturn look great over RGB SCART but the Dreamcast picture has a very slight flicker to it, looking closely at the screen I can see the scanlines rolling down the screen which seems to be causing the image to appear to flicker. The Megadrive and Saturn have static scanlines and don't flicker. All consoles are connected through a SCART to BNC cable. External sync is on and the BNC outputs have 75ohm terminators. Anyone else had this issue with the Dreamcast and know how to stop it? By no means is it game-breaking but now I've noticed it it's hard to un-notice! Thanks.

This happened to me too. Despite the dreamcast having csync I still needed a lm1881.

Did that fix the problem for you? Funnily enough I have just noticed it on Panzer Dragoon Zwei and Panzer Dragoon Saga on the Saturn so maybe it's a software issue of some kind..

I would say that you see INTERLACED video (480i) on the DC, while you see PROGRESSIVE video (240p) on the Saturn and MD. Some Saturn in-game title screens are in 480i as well and a handful of DC games are 240p (Bangaioh).

Ah so that's what it is. Brilliant, thanks for your help.

Ah I though he had a weird sync wobble like I did when he mentioned rolling down the screen.
