      I have almost exactly the same problem with my Yamaha RX379. I’m able to only get an intermittent image from the Dreamcast in VGA mode. 480i content is so far a non starter and subsequently so is 240p. What confuses me though is that I thought 480i content was line doubled to a progressive output, so why would the Dreamcast work with a 480p output but not the line doubled output of 480i content from a PS2? I wonder if a line x2 mode for 480/576i content would solve the problem. My TV does seem to accept the 480px2 mode when connected directly.

      Linex3 mode for 240p content might work for you; definitely worth a shot if you haven’t tried so already.

        Thanks for getting in touch! My monitor does 1:1 but the results are different. In ALTERNATING SCANLINE mode I get VERTICAL banding in addition to the alternating scanline effect, which makes no sense at all. Furthermore, at 50hz there is noticeable strobing with alternating scanlines that disappears at 60hz. Regular horizontal scanlines work perfectly on both the monitor and TV using its exact integer mode (4x480p with black bars). Disabling scanlines altogether also works fine. Here’s an image of 1:1 using alternating scanlines:

        Again, it could very well just be bad scaling, but these seem like odd results for 1:1 mode…

          480p LineX2 works.

            Appreciate that, thank you. Definitely possible! Unfortunately I don’t have any native NTSC consoles to test. Although it isn’t strictly speaking NTSC, it’s still present in PAL 60hz mode on PS2 via RGB scart and Gamecube games via component on the Wii.
