Dreamcast Scanlines - Big Problem
Hi Guys,
I'm using a modded Jap DC on a Sony Monitor, and much to my dispair the video signal shows what look to be very pronounced scan lines. I've tried running it through both AV and S-Video, but to no success.
So does anybody know whether this is a common problem or if its resolvable through a VGA box?
My Jap PS2 on the same monitor outputs fantastic RGB through a SCART lead.
I'm mystified.
Thanks

This is perfectly normal if the game in question is outputing a non-interlaced 15khz signal. Almost all PS2 games output an interlaced picture, where scanlines are flickered between fields so they are not as noticeable on 15khz displays (except in vertical shmups where fast moving objects still display noticable scanlines, especially on a tated monitor).
Anyway, if your monitor can support 31khz, get a DC-VGA box and you won't have the scanline problem anymore.

Tried the monitor from many different electricity outlet, but to no avail.JigsawMan wrote:try a different mains electricity outlet just for the TV and dreamcast.
Must be the non-interlaced signal. I think that I'll just have to buy a 21" PC monitor and run it through a DC VGA box. Real shame though.

I supect that the console is outputing PAL signal in stead of NTSC. This might due to the mod.Halloween Jack wrote:I'm using a modded Jap DC on a Sony Monitor, and much to my dispair the video signal shows what look to be very pronounced scan lines.

It would be no use, since the AV and S-Video is a stright pass thorugh of the VGA box.Halloween Jack wrote:So does anybody know whether this is a common problem or if its resolvable through a VGA box?

Well I'm not quite sure where to start with this, but determined to get Under Defeat up and running, I decided to skip any further investigative work in to understanding why the Sony monitor wouldn't output an S-Video or composite signal.
So, I popped in to Comet and paid £139 for a Sony KV-21CL10U (down from £259 as it was a demo). Got the new TV home, dusted it down and ordered a DC SCART lead. It arrived today, so I immediately tried it with the new TV - just fabulous!
Out of curiosity I also tried it with the Sony monitor that I'd been experiencing problems with - yep, you guessed it - perfect too!
So I now have a new TV, surplus to requirement, and a Sony monitor which accepts DC RGB, but not DC S-Video or composite input.
Totally confused, totally skint, but soothed by the splendour of G-Rev's latest.
