      Hello,
      I have a problem with my Atari Jaguar PAL.
      By plugging it directly onto the OSSC V1.6 it shifts the image to me up.
      The video signal is in RGBs 312p 15.62kHz 50.08Hz
      The offset is random. When it is strong, the top of the image appears at the bottom of the screen separated by a black bar.
      The offset is fixed, it changes only when I reset the OSSC.

      Bonjour,
      j’ai un problème avec mon Atari Jaguar PAL.
      En la branchant directement sur l’OSSC V1.6 il me décale l’image vers le haut.
      Le signal vidéo est en RGBs 312p 15,62kHz 50,08Hz
      Le décalage est aléatoire. Lorsqu’il est fort, le haut de l’image apparait en bas de l’écran séparé par une barre noir.
      Le décalage est fixe, il ne change que lorsque je reset l’OSSC.

        What type of SCART cable are you using?

          I use the original RGB cable

            Do you know if that uses composite video for sync or the Jaguar’s clean sync output?

              I do not know, sorry. I am waiting for a friend who has a PAL modified 60hz jaguar and who could plug it into my OSSC.

              Otherwise the image seems better centered now, but I still miss a lot of line at the top of the screen.

                You can try to adjust V.Backporch in advanced timings, reducing that should move the image down (in theory).

                  I don’t remember having such problems last time I used my PAL Jaguar and a clean sync cable. Have you tried adjusting vertical backporch or won’t your display tolerate this?

                    If you press info button, what is the value of VSM? Jaguar 288p is listed as a problematic source on the wikipage due to its field signalling.

                      Hello, my apologies, I solved the problem. I had stuck on the problem, without thinking of checking with the other mode. My jaguar is just incompatible with the X5, it works in X4 X3 and X2 without problem.

                      Thank you

                        Remember line 5 mode will always crop some of the picture on a 1080p TV.
