It displays the same resolution for 480p content as well. I’m getting the impression the OSSC isn’t outputting a traditional hdmi signal and is somehow “hacking” it to get the desired result. Either that or I just haven’t set it up right. I’m using it for a snes. All of the line doubling options seem to work fine, it upscales the output as necessary. It’s just the pass through that seems to be acting odd.
