    First off, make a new profile and reset settings and just check what the default (generic mode) image looks like. You shouldn’t have to fine tune for “some hours” just to get a decent basic image.

    If you started out from the FirebrandX profiles, you should try to enable max video LPF again, as his profiles usually changes the filter setting.

    Another possibility is you need to adjust the RGB gain or offset levels, if your video signal is too “hot”.

    If that still does not resolve it, you may have a hardware problem, or a cabling issue.
