      I wasn’t sure what to look up for this issue. I’ve worked on the settings for both a Turbo Duo connected via RGB SCART and a Famicom connected through a Retrotink/HDMI to Component adapter

      Both of them show the same sort of discoloration when there are bright objects over a dark background

      I took this higher angle shots since you can see the effect more clearly when not facing head on

      Does this look like a TV thing? OSSC settings thing? something else?

      Thanks

        Hard to say, have you done any kind of TV calibration, make sure you’re not running it over bright?

          Are you running the standard Generic 4:3?

          Have you verified that the same TV input and HDMI cable (plugged into a known-good HDMI source) doesn’t produce the issue?

            Maybe it is a TV settings thing. I’ve never messed with brightness or contrast much. It’s a new smallish 1080p tv. Vizio

            Brightness/contrast were set right in the middle so maybe toying with those will help

            I see the same issue with a Genesis through OSSC.

            the picture with a PS4 on the same hdmi input looks good as far as I can tell. I’m not sure if that’s the best comparison?

              On the OSSC settings, I’m using

              320×240 on genesis
              256×240 on PCE

              I can’t remember on famicom- i hadn’t saved those settings yet, but I think it may have been 256×240 also

              All three of these were at Line5x, but you can see the issue across all the modes

                  But the issue is also present if you go to Generic 4:3?

                    yes unfortunately so. i adjusted the TV to a much lower brightness then the contrast a lot higher and got most of it to disappear. i can still see it mainly on the Famicom connection. Maybe it’s just the TV itself, I can’t really tell

                      Recently tested this as well with a super Famicom using 5x
                      Link to the past and mega man x both have the dark bands

                      It will appear across the screen where text appears for example

                            This is on another TV – a 1080 Samsung maybe 5 years old?

                              This banding does not show up when using a cheapie scart upscaler I bought on Amazon

                              But I cannot figure out what setting or combo of settings on the OSSC May clean thus up

                              Do I have a bad OSSC?

                                My reply with my photos from an HDMI computer monitor disappeared

                                But it showed the banding in the same general location
