    Hi all. I’ve had my OSSC for almost a year now and I really like it, it saves me having to use a CRT to play my retro games. I know a fair bit about how they work, though I just want to ask about 480p. I recall 480p looking fairly decent on my old set and 480px2 looking amazing on another TV I tried it on, but it just seems to look a little off to me on my LG B8. 240p content upscaled looks amazing, but 480p content seems to have a similar effect to an optimised mode which has the H Samplerate set incorrectly.

    I’m just wondering does this happen to anyone else on their TV’s and if so, does anyone know how to fix it? I do remember the PS2 looking bad on my old set, but the Xbox and Dreamcast looked nice. Because of what’s happening, it makes some edges look blurred with a flicker-like effect. It’s very noticeable in Splinter Cell and also on Rayman 2 for Dreamcast using the Toro box.

    I’m using component cables on the Xbox. They’re ones I made myself, but the picture was nice on the other TV, so I’m assuming it’s not the cables. I’ve played around with the settings on the OSSC, but I probably won’t get too far without being able to use a test pattern of some sort.

    I have a similar tv (LG B7) and believe I’m experiencing similar issues with my PS2 in 480p mode (SoG, RGB SCART). It looks like some sort of edge enhancement or haloing effect, but slightly blurred. It’s like there’re two layers, a full colored layer and a transparent which are not completely alligned. It’s not as visible with component cables, probably because component is less sharp.

    I haven’t done any testing with my Xbox, but will try a few games tonight and report back my findings.

    Interesting that it seems to be the OLED sets it’s happening on. Although it will be hard to tell from an image, here’s an example of what mine is doing from the menu on Splinter Cell. You can see that while it’s supposed to be a checkerboard like type of pattern, it alternates between that pattern and horizontal lines.

    Splinter Cell Menu

    You can even see it on the font in “Create” over the letters where the lines are just horizontal. It’s even more noticeable here if you click “load full resolution”.

    Do you have your OLED’s in GAME mode with de-judder/de-blur turned off?

    Update:

    I see this checkerboard pattern too in the Splinter Cell menu. I managed to get rid of the vertical lines by increasing sampling phase to 303 (from 180). It’s in the sampling menu. With 303 I only see the thin horizontal lines which is how it’s supposed to look IIRC.

    TBH I don’t see any difference between 180 and 303 in-game, but that’s probably just my old eyes 🙂

    Let me know if this works for you.

    Update 2:

    I managed to establish that the OSSC is NOT responsible for this phenomenon. It looks exactly the same when using a component to HDMI transcoder.

    Bottom line:
    This horizontal blur is either caused by the Xbox component output or the LG OLED television’s handling of this output.
