      I know it’s a long time after the last post – but just in case anyone else has this issue, the problem was traced to bad connections between the OSSC and the Koryuu.

        “I guess you want to try composite for proper blending of faux transparencies?”

        Correct – I know of no other solution for this problem.

          Region is PAL. Clock frequency is unchanged from stock and Koryuu firmware hasn’t ben changed and thus is v1.1.

            Examples of what I mean:

              Panasonic hack = on = no picture on the Panasonic!

              The effect is least pronounced at a H samplerate of 854. Going below 856 requires setting an HDMI VIC of 10! What a puzzler. I would love to test VIC > 31 but this does not seem allowed by OSSC firmware – which is a shame.

              I am coming to the conclusion that while this TV is very good for Film content it is terrible for gaming (not least because the motion blurring is severe). I ran some tests using my Anybeam laser projector and I think that its laser scanning raster system seems to more closer emulate a CRT and this may be the real answer.

                Thanks for that. I could do with some more technical advice, but I’m not sure you can help to be honest.

                I am using the OSSC in Line 2x (Generic 4:3) mode with a PAL 288p linecount 50hz source and an unusual artefact is visible on the TV (Panasonic TX58DX902B) screen. Essentially there is some kind of vertical banding visible on the screen which I have determined is not caused by brightness variations in the panel itself. I have also ruled out the panel’s FALD feature as a cause.

                This evidently has something to do with the samplerate as the frequency of artefact changes as I alter it. Do you have any advice? See screenshots.

                    I tried the settings you mentioned and couldn’t get an image on the TV. Thanks for your suggestions though – is appreciated.
