      Hello everyone,
      Update:

      (Thanks Harrumph!)
      I’ve tracked down some of the issues and now I got a pretty good picture with FireBrandX profiles.
      However, the artifacts still persist, I will order new cables for my MD and MVS and I will try to clean the signal on my MD board by disabling composite video (some small jailbars still appear)
      I will soon put a Saturn on this setup and it seems that using the original RGB cable now 20 years old the picture is great (I’ve tested previously) so I really think this is a cabling issue.
      Thanks!

        Hi Harrumph,

        Thanks for your reply.
        I followed your tips but unfortunatelty the issue still persists.
        Using FirebrandX profiles I get a ton of jitter in the image that only goes away when reverting back to the generic 4:3 option. Changing the phase is not helping I guess.
        Yesterday I’ve lowered the brightness of my TV 3 levels to hide the noise and I was pretty much successfull on the MD, but I still see some in the MVS. Today I’ve lowered the gains like you said and I could increase one level of brightness to compensate without increasing the noise. (woo-hoo!)

        I hope to test the OSSC with a Saturn in the upcoming days via RGB with an official cable to rule out a OSSC problem and start to think it may be a cabling issue. The RGB for the MD is a regular RGB cable from Retrogamingcables.uk (not the packapunch model)
        If the issue goes away with the Saturn, I will invest in new cables.
        If someone has more tips, all of them are welcome.
        Thanks!
