If you are referring to those square dotted lines in the screenshots above then as far as I am aware it isn’t anything to do with the Dreamcast’s dithering. The dithering lines are straight and vertical where-as those in your sreeenshot are dotted and scattered. If they are always located at the same place when you use your Dreamcast I’d likely think it’s related to the Dreamcast’s hardware than the cable. However trying another cable would be first and cheapest option to rule out…

Damn! I thought something like that. Thanks for the tipps.
So I need to get another cable…. but there are tons out there. Before I buy one after another and spend lots of money do you have any recommendations?

This is incompatible with OSSC and also doesn’t allow the fine adjustments that OSSC allows, so you will always have the squashed aspect ratio with this box.December 17, 2017 at 3:02 PM #18045
Another standard VGA cable, like you already have, with the separate RCA connectors would be fine. I’ve picked a few up on eBay and they have all worked okay for me.
Between the OSSC and Akura I’d stick with the OSSC. I have my Dreamcast hooked up directly to the OSSC with a custom VGA cable that has a built in 15/31khz selector switch. I have the Akura and it does not output 240p and 480i games. It also does not support line doubling that the OSSC supports for multiple resolutions. I also find the Akura shifts the image to the far right of the screen. If you do want to get a VGA box to accompany the OSSC (for 15/31khz switching), though it’s probably a little overkill for your needs, I would certainly recommend the Toro…

Thank you. May you tell me, which cable you are using? Maybe you have a link as well?December 21, 2017 at 12:18 AM #18082
I have a custom VGA cable, it is essentially similar to a standard VGA cable only with a 15/31KHZ selector switch in the middle. I’ve got standard VGA cables bought off eBay and they have all worked fine with the OSSC…

Not to derail the discussion, but what is this even? An inline upscaler or linedoubler?December 22, 2017 at 10:49 AM #18107
It’s so you can play 15khz and 31khz (VGA) Dreamcast games using the same cable. On the stock Dreamcast VGA boxes you have to swap back to your SCART lead if your game doesn’t support VGA.January 24, 2018 at 4:17 PM #18703
I bought on sunday a new TV (LG 42LF450-ZA) and connected the Dreamcast as first into the OSSC to VGA and then directly into the new TV. It didn’t solved the problem and it still had these horizontal, wavy square lines.
As you can see here:
When I put the VGA into my previous Toshiba LCD this issue didn’t appear. It only happened through the OSSC with VGA.
However, I could rid of the problem after I connected the audio phone connector to the OSSC <-> TV.
Weird somehow… maybe it has something to do with the shielding…
Everything is fine now and it works
